TSH follows a circadian rhythm—it's highest overnight and in the early morning, then drops during the day.

The timing relative to your dose makes minimal difference to TSH or Free T4 results. However, if you take liothyronine (T3) or desiccated thyroid extract (DTE\/NDT), collect your sample before taking your morning dose. T3 peaks in the blood within hours of taking it, so testing shortly after a dose shows the peak rather than your average level.\u003c\/p\u003e\n \u003cp\u003e\u003cstrong\u003eBiotin Supplements:\u003c\/strong\u003e Stop biotin (vitamin B7) supplements for 2 days before testing. Biotin is found in many hair, skin, and nail supplements—often at high doses—and interferes with thyroid hormone assays, potentially giving falsely high or low results.

It tells your thyroid how much hormone to produce. The clever thing about TSH is that it works in reverse—when thyroid hormones are low, TSH rises to stimulate more production; when thyroid hormones are high, TSH drops because the pituitary senses there's already enough. This makes TSH the most sensitive single marker for thyroid dysfunction. High TSH (typically above 4-4.5 mIU\/L) indicates hypothyroidism—your pituitary is calling for more hormone because levels are low. Low TSH (below 0.4-0.5 mIU\/L) indicates hyperthyroidism—there's so much thyroid hormone that the pituitary has stopped asking for more. TSH can be abnormal while T4 and T3 are still in the normal range (subclinical thyroid disease), making it an early warning sign.

'Free' means it's not bound to proteins and is available to your tissues. Most T3 isn't made directly by your thyroid; instead, your body converts the more abundant T4 into T3 as needed in tissues throughout your body. This conversion happens via deiodinase enzymes and requires adequate selenium, zinc, and iron. Low Free T3 can occur with hypothyroidism, but also with 'low T3 syndrome' where conversion is impaired—this happens with calorie restriction, chronic illness, stress, and certain nutrient deficiencies. Some people on levothyroxine have normal T4 but low-normal T3 and still feel unwell, suggesting a conversion issue. Free T3 gives insight into what's actually happening at the cellular level.

T4 acts as a reservoir or prohormone that circulates in your blood and gets converted to the more active T3 when your body needs it. 'Free' T4 is more clinically useful than total T4 because it's not affected by changes in binding proteins (which can fluctuate with pregnancy, oestrogen, liver disease, and certain medications). In hypothyroidism, Free T4 is low; in hyperthyroidism, it's high. If you're taking levothyroxine treatment, Free T4 shows how well your replacement therapy is working. Measuring both Free T4 and Free T3 together gives a fuller picture than either alone—especially for identifying conversion problems where T4 is adequate but T3 is low.

Elevated TPO antibodies are the hallmark of autoimmune thyroid disease, present in about 90% of people with Hashimoto's thyroiditis (the most common cause of hypothyroidism) and many with Graves' disease. However, positive antibodies don't always mean you have or will develop thyroid disease—about 10-15% of the general population have elevated TPO antibodies with normal thyroid function. What elevated antibodies do tell you is that there's autoimmune activity against your thyroid, and you're at increased risk of developing thyroid dysfunction in the future.

Like TPO antibodies, elevated thyroglobulin antibodies indicate autoimmune thyroid disease. They're found in about 70-80% of Hashimoto's patients and about 50-70% of Graves' disease patients. Some people have elevated thyroglobulin antibodies but negative TPO antibodies, so testing both gives a more complete picture of autoimmune involvement. In thyroid cancer follow-up, thyroglobulin antibodies are important because they can interfere with thyroglobulin measurements used to monitor for recurrence. In the general population, positive thyroglobulin antibodies (like TPO antibodies) indicate increased risk of developing thyroid dysfunction over time, even if current thyroid function is normal. Results outside the normal range may need a follow-up with your GP.\u003c\/p\u003e\n \u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003c\/div\u003e\n \u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003c!-- Vitamins Category --\u003e\n \u003cinput type=\"checkbox\" id=\"meditest-cat-vitamins-advthyroid\"\u003e\n \u003cdiv class=\"category-section\"\u003e\n \u003clabel for=\"meditest-cat-vitamins-advthyroid\" class=\"category-header\"\u003e\n \u003cspan class=\"category-title\"\u003eVitamins (3)\u003c\/span\u003e\n \u003cspan class=\"category-dropdown-icon\"\u003e▼\u003c\/span\u003e\n \u003c\/label\u003e\n \u003cdiv class=\"category-content\"\u003e\n \u003cdiv class=\"category-biomarkers\"\u003e\n \n \u003cinput type=\"checkbox\" id=\"meditest-bio-vitd-advthyroid\"\u003e\n \u003cdiv class=\"biomarker-item\"\u003e\n \u003clabel for=\"meditest-bio-vitd-advthyroid\" class=\"biomarker-header\"\u003e\n \u003cspan class=\"biomarker-name\"\u003eVitamin D (25-OH)\u003c\/span\u003e\n \u003cspan class=\"dropdown-icon\"\u003e▼\u003c\/span\u003e\n \u003c\/label\u003e\n \u003cdiv class=\"biomarker-content\"\u003e\n \u003cp\u003eVitamin D is measured as 25-hydroxyvitamin D (25-OH D), which reflects your body's vitamin D status from both sun exposure and dietary\/supplement intake. Vitamin D is increasingly recognised as important for thyroid health—not just for symptoms that overlap with hypothyroidism (fatigue, muscle weakness, mood changes) but for thyroid function itself. Low vitamin D is associated with higher rates of autoimmune thyroid disease, and people with Hashimoto's thyroiditis are more likely to be vitamin D deficient than the general population. Vitamin D plays a role in immune regulation, and adequate levels may help modulate autoimmune activity. In the UK, vitamin D deficiency is common, especially in winter. Levels above 50 nmol\/L are generally considered adequate; above 75 nmol\/L may be optimal, particularly if you have autoimmune thyroid disease.

B12 is essential for red blood cell formation, neurological function, and DNA synthesis. B12 deficiency causes symptoms that closely mimic hypothyroidism—fatigue, brain fog, depression, weakness, and tingling in hands and feet—which is why it's important to check alongside thyroid function. There's also a specific connection: autoimmune thyroid disease (Hashimoto's) often coexists with pernicious anaemia (autoimmune destruction of cells needed to absorb B12). People with one autoimmune condition are more likely to develop others. Low B12 can also occur with metformin use, vegetarian\/vegan diets, and age-related absorption decline.

It works closely with vitamin B12—deficiency in either causes similar symptoms including fatigue, weakness, and anaemia. Low folate causes macrocytic anaemia (large, immature red blood cells) and can contribute to elevated homocysteine, which is associated with cardiovascular risk. Folate deficiency can occur with poor dietary intake (it's found in leafy greens, legumes, and fortified foods), malabsorption conditions, alcohol excess, and certain medications. In the context of thyroid health, folate deficiency can worsen fatigue and cognitive symptoms, and optimal folate status supports overall wellbeing. Serum folate reflects recent intake (days to weeks) rather than long-term stores. Note that folate testing from finger-prick samples can be unreliable, which is why this test uses venous collection.

Iron is directly involved in thyroid hormone production—thyroid peroxidase (the enzyme that makes thyroid hormones) requires iron to function. Low ferritin is associated with impaired thyroid function and can worsen hypothyroid symptoms even when thyroid hormones are technically in range. Symptoms of low ferritin—fatigue, weakness, cold intolerance, hair loss, difficulty concentrating—overlap substantially with hypothyroidism, so it's important to check both. Women of reproductive age are particularly prone to low ferritin due to menstrual blood loss. Many thyroid specialists suggest optimal ferritin is 70-90 µg\/L for people with thyroid conditions, though the standard reference range starts much lower. However, ferritin is also an acute phase reactant—it rises with inflammation—so hs-CRP is included in this panel to help interpret ferritin accurately.

CRP is produced by your liver in response to inflammatory signals from anywhere in the body. The 'high-sensitivity' test detects the subtle elevations relevant to chronic inflammation and cardiovascular risk, not just the dramatic elevations seen with acute infection. In the context of thyroid health, hs-CRP serves several purposes. First, it helps interpret ferritin—if CRP is elevated, ferritin may be artificially raised by inflammation rather than reflecting true iron stores. Second, autoimmune thyroid conditions can be associated with chronic low-grade inflammation. Third, both hypo- and hyperthyroidism can affect inflammatory markers. Finally, hs-CRP is a useful general health marker—persistent elevation is associated with increased cardiovascular risk and warrants investigation into the cause.

TSH tells the thyroid gland how much hormone to produce. The pituitary constantly monitors thyroid hormone levels in the blood and adjusts TSH output accordingly: when thyroid hormones are low, TSH rises to stimulate the thyroid to produce more; when thyroid hormones are high, TSH falls to slow production. This negative feedback loop makes TSH the most sensitive early indicator of thyroid dysfunction—often the first marker to become abnormal, sometimes before the thyroid hormones themselves move outside normal range.\u003c\/p\u003e\n \u003cp\u003eAn elevated TSH indicates that the thyroid is underperforming (hypothyroidism). The pituitary is working harder to stimulate a sluggish thyroid. Hypothyroidism is common, affecting approximately 2% of the UK population, with higher rates in women and with increasing age. Symptoms include fatigue, weight gain, feeling cold, dry skin, constipation, hair loss, depression, and difficulty concentrating. A low or suppressed TSH indicates that the thyroid is overactive (hyperthyroidism). The pituitary is backing off because thyroid hormone levels are already too high. Symptoms include weight loss, anxiety, tremor, palpitations, heat intolerance, diarrhoea, and difficulty sleeping.\u003c\/p\u003e\n \u003cp\u003eNormal TSH is typically 0.4-4.0 mU\/L, though some guidelines suggest 0.4-2.5 mU\/L may be more appropriate. TSH between 4-10 mU\/L with normal Free T4 is termed \"subclinical hypothyroidism\"—this may or may not require treatment depending on symptoms, antibody status, and other factors. TSH below 0.1 mU\/L with elevated Free T4\/T3 indicates overt hyperthyroidism. Results outside the normal range may need a follow-up with your GP.\u003c\/p\u003e\n \u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003cinput type=\"checkbox\" id=\"meditest-bio-ft4-thyroidfn\"\u003e\n \u003cdiv class=\"biomarker-item\"\u003e\n \u003clabel for=\"meditest-bio-ft4-thyroidfn\" class=\"biomarker-header\"\u003e\n \u003cspan class=\"biomarker-name\"\u003eFree T4 (Free Thyroxine)\u003c\/span\u003e\n \u003cspan class=\"dropdown-icon\"\u003e▼\u003c\/span\u003e\n \u003c\/label\u003e\n \u003cdiv class=\"biomarker-content\"\u003e\n \u003cp\u003eFree T4 measures the unbound, biologically active fraction of thyroxine circulating in your blood. Thyroxine (T4) is the main hormone produced by the thyroid gland, accounting for about 80% of its hormonal output. Most T4 in blood is bound to carrier proteins (primarily thyroxine-binding globulin, or TBG) and is inactive; only the free fraction (approximately 0.03%) is available to enter cells. This \"free\" T4 is what we measure because it reflects the hormone actually available to your tissues, unaffected by variations in binding protein levels.\u003c\/p\u003e\n \u003cp\u003eT4 is sometimes called a \"storage\" or \"prohormone\" because it must be converted to the more active T3 (triiodothyronine) to exert its full effects on cells. This conversion happens in peripheral tissues (liver, kidney, muscles, brain) by enzymes called deiodinases. Free T4 provides a good overall measure of thyroid hormone production. Combined with TSH, it allows classification of thyroid status: high TSH with low Free T4 confirms primary hypothyroidism; low TSH with high Free T4 confirms hyperthyroidism; high TSH with normal Free T4 indicates subclinical hypothyroidism.\u003c\/p\u003e\n \u003cp\u003eNormal Free T4 is typically 9-25 pmol\/L, though optimal may be in the upper half of this range for many people. When interpreting Free T4, always consider it alongside TSH—the combination tells a clearer story than either alone. Some people feel well with Free T4 at the lower end of normal; others need it in the upper range. Individual variation exists, and clinical symptoms matter as much as laboratory numbers. Results outside the normal range may need a follow-up with your GP.\u003c\/p\u003e\n \u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003cinput type=\"checkbox\" id=\"meditest-bio-ft3-thyroidfn\"\u003e\n \u003cdiv class=\"biomarker-item\"\u003e\n \u003clabel for=\"meditest-bio-ft3-thyroidfn\" class=\"biomarker-header\"\u003e\n \u003cspan class=\"biomarker-name\"\u003eFree T3 (Free Triiodothyronine)\u003c\/span\u003e\n \u003cspan class=\"dropdown-icon\"\u003e▼\u003c\/span\u003e\n \u003c\/label\u003e\n \u003cdiv class=\"biomarker-content\"\u003e\n \u003cp\u003eFree T3 measures the unbound, active fraction of triiodothyronine. T3 is the most metabolically active thyroid hormone—approximately 3-4 times more potent than T4 at the cellular level. T3 is the hormone that actually enters cell nuclei and switches on thyroid-responsive genes, affecting metabolism, energy production, protein synthesis, and countless other cellular functions. Only about 20% of T3 is produced directly by the thyroid gland; the majority (approximately 80%) is produced by conversion of T4 to T3 in peripheral tissues.\u003c\/p\u003e\n \u003cp\u003eIncluding Free T3 in a thyroid panel provides additional information beyond TSH and Free T4 alone. It's particularly useful for detecting hyperthyroidism (where Free T3 may be elevated earlier or more prominently than Free T4, especially in \"T3 toxicosis\"), assessing T4-to-T3 conversion efficiency (some people convert poorly, leading to low T3 despite adequate T4), and evaluating symptoms in patients on thyroid replacement therapy who feel unwell despite \"normal\" TSH and Free T4. Some patients feel their T3 levels are important for their wellbeing, though this remains somewhat debated in mainstream endocrinology.\u003c\/p\u003e\n \u003cp\u003eNormal Free T3 is typically 3.5-6.5 pmol\/L. Low Free T3 with normal TSH and Free T4 often indicates non-thyroidal illness rather than a primary thyroid problem—the body downregulates T3 production during illness, starvation, or severe stress as a protective mechanism. Elevated Free T3 with suppressed TSH is a key finding in hyperthyroidism. In hypothyroid patients on levothyroxine, Free T3 usually remains normal even if Free T4 is at the higher end, due to peripheral regulation of conversion.

A single measurement provides a useful snapshot of your thyroid status at one point in time. If results are borderline or unexpected, your GP may recommend repeat testing to confirm the findings. For those monitoring a thyroid condition, consistent timing of tests (same time of day, same relationship to medication doses) helps make results comparable over time.\u003c\/p\u003e\n \u003cp\u003eThis test measures thyroid function (how well your thyroid is working) but does not include thyroid antibodies (which would indicate autoimmune thyroid disease).

In women, FSH stimulates the growth and development of ovarian follicles—the fluid-filled sacs that contain eggs. As follicles develop, they produce oestrogen. FSH levels vary throughout the menstrual cycle: they're highest at the beginning of the cycle (follicular phase) to recruit follicles, drop mid-cycle as the dominant follicle takes over, and remain low in the second half (luteal phase).\u003c\/p\u003e\n \u003cp\u003eFSH is a key marker for assessing ovarian reserve and menopausal status. As ovarian reserve declines with age, the pituitary produces more FSH in an attempt to stimulate the ovaries—so rising baseline FSH (measured on days 2-5 of the cycle) indicates diminishing ovarian reserve. Very high FSH (typically above 25-40 IU\/L) with low oestradiol indicates menopause or premature ovarian insufficiency. In PCOS, FSH is often normal or low relative to LH.

LH levels remain relatively low during most of the cycle but surge dramatically mid-cycle—this LH surge triggers ovulation, causing the mature follicle to rupture and release the egg. After ovulation, LH stimulates the empty follicle to become the corpus luteum, which produces progesterone.\u003c\/p\u003e\n \u003cp\u003eThe ratio of LH to FSH is clinically useful. In a normal cycle, the LH:FSH ratio is approximately 1:1. In PCOS, this ratio is often elevated (2:1 or higher), with LH disproportionately high compared to FSH. This elevated LH contributes to excess androgen production by the ovaries, causing symptoms like acne, hirsutism (excess hair growth), and irregular periods. Like FSH, LH rises after menopause due to loss of negative feedback from the ovaries.

Oestradiol also has significant effects on mood and cognitive function.\u003c\/p\u003e\n \u003cp\u003eOestradiol levels fluctuate significantly throughout the menstrual cycle.

Baseline oestradiol (days 2-5) should be relatively low; an elevated baseline can indicate diminished ovarian reserve or ovarian cysts. After menopause, oestradiol falls dramatically to very low levels. Low oestradiol causes menopausal symptoms including hot flushes, night sweats, vaginal dryness, and contributes to bone loss.

Conversely, insulin resistance, obesity, and androgens suppress SHBG production. In PCOS, low SHBG is common—this means more testosterone is free and bioavailable, contributing to hyperandrogenic symptoms even if total testosterone isn't dramatically elevated. Low SHBG is also associated with metabolic syndrome and increased cardiovascular risk. High SHBG can cause symptoms of hormone deficiency despite normal total hormone levels.

A high FAI helps confirm biochemical hyperandrogenism, one of the diagnostic criteria for PCOS. Normal FAI in women is typically below 5-8% (varies by laboratory). An elevated FAI helps explain symptoms like acne, hirsutism, and scalp hair loss even when total testosterone appears normal.

TSH stimulates the thyroid to produce thyroid hormones (T4 and T3). It works through a negative feedback loop: when thyroid hormone levels are low, TSH rises to stimulate more production; when thyroid hormones are adequate, TSH falls.\u003c\/p\u003e\n \u003cp\u003eTSH is the most sensitive initial test for thyroid dysfunction. An elevated TSH indicates hypothyroidism (underactive thyroid)—the pituitary is working harder to stimulate an underperforming thyroid. A suppressed TSH indicates hyperthyroidism (overactive thyroid). Thyroid disorders are much more common in women and significantly affect reproductive health: hypothyroidism can cause heavy or irregular periods, anovulation, fertility problems, and increased miscarriage risk; hyperthyroidism can cause light or absent periods. Even subclinical hypothyroidism (elevated TSH with normal T4) may affect fertility and pregnancy outcomes. Thyroid dysfunction can also cause symptoms that mimic other conditions—fatigue, weight changes, mood changes, and hair loss.

Most T4 in the blood is bound to carrier proteins and inactive; only the small 'free' fraction can enter cells and exert effects. T4 is the primary hormone produced by the thyroid gland and serves as a reservoir that's converted to the more active T3 in tissues as needed.\u003c\/p\u003e\n \u003cp\u003eFree T4 is measured alongside TSH to confirm and characterise thyroid dysfunction. In primary hypothyroidism, TSH is elevated and Free T4 is low (the thyroid isn't producing enough hormone). In primary hyperthyroidism, TSH is suppressed and Free T4 is elevated (the thyroid is overproducing). Subclinical hypothyroidism shows elevated TSH with normal Free T4—the pituitary is working harder to maintain normal thyroid hormone levels. Free T4 is preferred over total T4 because it's not affected by changes in binding proteins (which can occur with oestrogen, pregnancy, or certain medications). Normal Free T4 with abnormal TSH suggests early or subclinical thyroid dysfunction.

TSH tells the thyroid how much hormone to produce. The pituitary constantly monitors thyroid hormone levels in the blood and adjusts TSH accordingly: when thyroid hormones are low, TSH rises to stimulate more production; when thyroid hormones are high, TSH falls to slow production. This feedback loop makes TSH the most sensitive early indicator of thyroid dysfunction.\u003c\/p\u003e\n \u003cp\u003eAn elevated TSH indicates that the thyroid is underperforming (hypothyroidism)—the pituitary is working harder to stimulate a sluggish thyroid. This is the most common thyroid disorder, affecting approximately 2% of the UK population and more common in women and with increasing age. A low or suppressed TSH indicates that the thyroid is overactive (hyperthyroidism)—the pituitary is backing off because thyroid hormones are already too high.\u003c\/p\u003e\n \u003cp\u003eNormal TSH is typically 0.4-4.0 mU\/L. TSH in the range 4-10 mU\/L with normal Free T4 is termed \"subclinical hypothyroidism\" and may progress to overt hypothyroidism, especially if thyroid antibodies are positive.

T4 is the main hormone produced by the thyroid gland (about 80% of thyroid hormone output). Most T4 in blood is bound to carrier proteins (mainly thyroxine-binding globulin, TBG) and is inactive; only the free fraction (about 0.03%) is available to enter cells. T4 is sometimes called a \"storage\" hormone because it must be converted to the more active T3 to have its full effect on metabolism.\u003c\/p\u003e\n \u003cp\u003eFree T4 gives a more accurate picture of thyroid status than total T4 because it's not affected by changes in binding protein levels (which can vary with pregnancy, oestrogen therapy, liver disease, and other conditions). Free T4 combined with TSH allows classification of thyroid status: high TSH with low Free T4 = primary hypothyroidism; low TSH with high Free T4 = hyperthyroidism; high TSH with normal Free T4 = subclinical hypothyroidism.\u003c\/p\u003e\n \u003cp\u003eNormal Free T4 is typically 9-25 pmol\/L. When interpreting results, consider both Free T4 and TSH together rather than in isolation.

T3 is the most metabolically active thyroid hormone—about 3-4 times more potent than T4. Most T3 in the body (approximately 80%) is produced by conversion of T4 to T3 in peripheral tissues (liver, kidney, muscles, brain) by deiodinase enzymes, rather than being directly secreted by the thyroid. T3 is the hormone that actually enters cells and exerts thyroid effects on metabolism.\u003c\/p\u003e\n \u003cp\u003eFree T3 provides additional information beyond TSH and Free T4. It can be particularly useful in hyperthyroidism (where Free T3 may be elevated earlier or more prominently than Free T4), in assessing T4-to-T3 conversion (some people convert poorly), and in monitoring patients on T3-containing thyroid preparations. In hypothyroidism, Free T3 often remains normal until the condition is quite advanced because the body prioritises T3 production.\u003c\/p\u003e\n \u003cp\u003eNormal Free T3 is typically 3.5-6.5 pmol\/L. Low Free T3 with normal TSH and Free T4 can occur in non-thyroidal illness (\"sick euthyroid syndrome\"), starvation, or certain medications—this is usually not a primary thyroid problem. Elevated Free T3 with suppressed TSH is seen in hyperthyroidism. Some patients feel T3 levels are important for their wellbeing, though this is debated in medical literature.

Anti-TPO antibodies are autoantibodies that attack this enzyme, causing inflammation and gradual destruction of thyroid tissue. This autoimmune attack is the underlying mechanism in Hashimoto's thyroiditis, the most common cause of hypothyroidism in the UK and other iodine-sufficient countries.\u003c\/p\u003e\n \u003cp\u003eAnti-TPO antibodies are found in approximately 90% of people with Hashimoto's thyroiditis and about 70% of people with Graves' disease (autoimmune hyperthyroidism). However, approximately 10-15% of the general population have detectable anti-TPO antibodies without currently having thyroid dysfunction—this is called \"thyroid autoimmunity\" or \"positive antibodies with euthyroidism.\" People with positive anti-TPO antibodies and normal thyroid function have an increased risk (about 2-4% per year) of developing thyroid dysfunction over time, particularly hypothyroidism.\u003c\/p\u003e\n \u003cp\u003eNormal is typically \u0026lt;35 IU\/mL (or \u0026lt;60 kU\/L depending on the assay), with significant elevation usually above 100-500 IU\/mL.

Iodine is attached to thyroglobulin to produce T4 and T3, which are then released from the thyroglobulin molecule. Anti-thyroglobulin antibodies (anti-Tg or TgAb) are autoantibodies that target this protein. Like anti-TPO antibodies, they indicate autoimmune thyroid disease.\u003c\/p\u003e\n \u003cp\u003eAnti-Tg antibodies are found in approximately 60-85% of people with Hashimoto's thyroiditis and 30-60% of people with Graves' disease. They are generally considered less sensitive and specific than anti-TPO antibodies for diagnosing autoimmune thyroid disease. However, about 3-5% of people with autoimmune thyroiditis have only anti-Tg antibodies without anti-TPO antibodies, so testing both increases diagnostic sensitivity. Anti-Tg antibodies are also important in thyroid cancer follow-up, where they can interfere with thyroglobulin tumour marker measurements.\u003c\/p\u003e\n \u003cp\u003eNormal is typically \u0026lt;40 IU\/mL (or \u0026lt;115 kU\/L depending on the assay).

If both antibody tests are positive, this strongly suggests autoimmune thyroid disease.

It's a key component of haemoglobin (the protein in red blood cells that carries oxygen from the lungs to tissues) and myoglobin (which stores oxygen in muscle cells). Iron is also involved in energy production, DNA synthesis, and immune function. The body cannot make iron, so it must be obtained from food—either as haem iron from animal sources (readily absorbed) or non-haem iron from plant sources (less readily absorbed).\u003c\/p\u003e\n \u003cp\u003eSerum iron measures the amount of iron circulating in your blood, bound to the transport protein transferrin. It's important to understand that serum iron is just a snapshot of iron in transit—it fluctuates significantly throughout the day and is heavily influenced by recent dietary intake, making it the least reliable marker when viewed in isolation. A single serum iron reading can vary by 30-40% within the same person on the same day.\u003c\/p\u003e\n \u003cp\u003eLow serum iron can indicate iron deficiency, but it can also occur in chronic disease and inflammation (where iron is redistributed into storage rather than circulation). High serum iron may indicate iron overload conditions such as haemochromatosis, or can occur after recent iron supplementation or iron-rich meals. Because of its variability, serum iron should always be interpreted alongside ferritin, TIBC, and transferrin saturation for a complete picture. Results outside the normal range may need a follow-up with your GP.\u003c\/p\u003e\n \u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003cinput type=\"checkbox\" id=\"meditest-bio-ferritin\"\u003e\n \u003cdiv class=\"biomarker-item\"\u003e\n \u003clabel for=\"meditest-bio-ferritin\" class=\"biomarker-header\"\u003e\n \u003cspan class=\"biomarker-name\"\u003eFerritin\u003c\/span\u003e\n \u003cspan class=\"dropdown-icon\"\u003e▼\u003c\/span\u003e\n \u003c\/label\u003e\n \u003cdiv class=\"biomarker-content\"\u003e\n \u003cp\u003eFerritin is a protein that stores iron within cells, particularly in the liver, spleen, and bone marrow. When your body has more iron than it immediately needs, it stores the excess in ferritin for future use. When iron is needed (for example, to make new red blood cells), it's released from ferritin stores. A small amount of ferritin is released into the blood, and measuring this serum ferritin gives a reliable indication of your total body iron stores—it's the single most useful marker for assessing iron status in most situations.\u003c\/p\u003e\n \u003cp\u003eLow ferritin is the earliest and most sensitive indicator of iron depletion. Ferritin falls before serum iron drops and before anaemia develops, making it valuable for detecting iron deficiency at an early stage when it's easiest to correct. A ferritin level below 30 µg\/L is widely considered to indicate depleted iron stores, even if haemoglobin is still normal. Some experts consider levels below 50 µg\/L as suboptimal, particularly for certain groups like athletes or those with symptoms of iron deficiency.\u003c\/p\u003e\n \u003cp\u003eHowever, ferritin is also an \"acute phase reactant,\" meaning it rises in response to inflammation, infection, liver disease, chronic alcohol consumption, and some malignancies—even when actual iron stores are low. This can mask true iron deficiency. If ferritin appears normal or elevated but you have symptoms of iron deficiency and other markers (like transferrin saturation) suggest deficiency, inflammation may be masking the picture. This is why hs-CRP is included in this panel—if both ferritin and hs-CRP are elevated, inflammation is likely contributing to the ferritin result. Very high ferritin (above 300-500 µg\/L in the absence of inflammation) may indicate iron overload and warrants further investigation.

Think of transferrin as a delivery truck and TIBC as measuring the total carrying capacity of all the trucks. TIBC essentially reflects how much transferrin is available in your blood and thus your body's capacity to transport iron.\u003c\/p\u003e\n \u003cp\u003eTIBC responds inversely to iron status: when iron stores are low, your body compensates by producing more transferrin to capture and transport whatever iron is available—so TIBC increases. When iron stores are adequate or excessive, less transferrin is needed, and TIBC decreases. This makes TIBC a useful marker for distinguishing different types of iron problems.\u003c\/p\u003e\n \u003cp\u003eIn iron deficiency, TIBC is typically elevated (above 70 µmol\/L)—your body is producing more transferrin to try to capture more iron. In iron overload conditions like haemochromatosis, TIBC is typically low or normal because less transport capacity is needed. In the anaemia of chronic disease (where iron is \"trapped\" in storage by inflammation), TIBC is typically low or normal, which helps distinguish it from true iron deficiency anaemia where TIBC would be high. TIBC is less affected by day-to-day variation than serum iron, making it a more stable marker.

It's calculated by dividing serum iron by TIBC and multiplying by 100. If TIBC represents the total carrying capacity of your iron \"delivery trucks,\" transferrin saturation tells you what percentage of that capacity is currently being used.\u003c\/p\u003e\n \u003cp\u003eNormal transferrin saturation is typically between 20-45%. In iron deficiency, transferrin saturation falls below 20%—there's plenty of transport capacity available (high TIBC) but not enough iron to fill it. A transferrin saturation below 16-20% is a strong indicator of iron deficiency, and even if ferritin is normal (perhaps due to concurrent inflammation), a low transferrin saturation suggests that iron delivery to tissues is inadequate.\u003c\/p\u003e\n \u003cp\u003eConversely, transferrin saturation above 45% suggests iron overload—more iron is being transported than normal. Persistently elevated transferrin saturation (especially above 45-50%) is often the first abnormality detected in hereditary haemochromatosis, sometimes before ferritin becomes elevated. If your transferrin saturation is consistently high, testing for haemochromatosis (HFE gene mutation) may be recommended. Transferrin saturation combines information from serum iron and TIBC, making it a more informative single number than either alone.

The \"high-sensitivity\" assay can detect the low levels of chronic, smouldering inflammation that standard CRP tests would miss.\u003c\/p\u003e\n \u003cp\u003eThe reason hs-CRP is included here relates to ferritin's dual nature: ferritin is both an iron storage protein AND an acute phase reactant that rises with inflammation. This creates a diagnostic challenge—a person with true iron deficiency but concurrent inflammation (from infection, autoimmune disease, chronic illness, or even obesity) might have a \"normal\" or even elevated ferritin, masking their iron-depleted state. By measuring hs-CRP alongside ferritin, we can identify when inflammation might be artificially elevating ferritin.\u003c\/p\u003e\n \u003cp\u003eIf ferritin appears normal but hs-CRP is elevated, this suggests inflammation is present and ferritin may not accurately reflect iron stores—true iron deficiency could still exist.

Progesterone is a steroid hormone produced by the corpus luteum—the structure that forms in the ovary after an egg is released.

In the first half of the menstrual cycle (follicular phase), progesterone levels are very low, typically below 5 nmol\/L. After ovulation, progesterone rises dramatically as the corpus luteum develops and begins secreting it in large quantities. This post-ovulatory rise is what makes progesterone useful for confirming that ovulation has occurred.\u003c\/p\u003e\n \u003cp\u003eProgesterone's primary function is to prepare the uterus for pregnancy and support early pregnancy if conception occurs. It causes the uterine lining (endometrium) to become secretory—developing the blood supply and glandular structures necessary for implantation and nourishment of an embryo. Progesterone also raises basal body temperature slightly (which is why temperature tracking can indicate ovulation), causes cervical mucus to thicken (preventing further sperm entry after fertilisation), and has calming effects on the brain that can cause the typical luteal phase symptoms of tiredness and mood changes.\u003c\/p\u003e\n \u003cp\u003eIn the mid-luteal phase (around day 21 of a 28-day cycle, or 7 days after ovulation), progesterone should be at or near its peak. Levels above 30 nmol\/L generally confirm ovulation and indicate adequate luteal function. Levels between 16-30 nmol\/L suggest ovulation occurred but luteal phase support may be borderline. Levels below 16 nmol\/L (and particularly below 10 nmol\/L) suggest either ovulation did not occur (anovulatory cycle) or luteal phase defect where the corpus luteum is not producing sufficient progesterone.\u003c\/p\u003e\n \u003cp\u003eIt's important to note that progesterone levels fluctuate significantly even within the same day and across the luteal phase—a single low result doesn't definitively diagnose a problem. If your result is low, it's worth checking the timing was correct (truly 7 days before your period) and potentially repeating the test in a subsequent cycle. Consistently low mid-luteal progesterone across multiple cycles is more significant. If you're trying to conceive and have low progesterone with suspected luteal phase defect, your doctor may discuss progesterone supplementation. Results outside the normal range may need a follow-up with your GP or fertility specialist.\u003c\/p\u003e\n \u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003c\/div\u003e\n \u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003c\/div\u003e\n \u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003c!-- Section 7: Medical Disclaimer --\u003e\n \u003cdiv class=\"disclaimer-section\"\u003e\n \u003ch3\u003eMedical Disclaimer\u003c\/h3\u003e\n \u003cp\u003eProgesterone testing provides useful information about ovulation, but a single progesterone result has limitations. Progesterone levels naturally fluctuate—even within the same day—so a single low result doesn't definitively confirm anovulation or luteal phase defect. Timing is critical: if your cycle length varies from 28 days and you tested on day 21 regardless, you may have missed the true mid-luteal peak. For the most reliable assessment, test 7 days before your expected period, which may require cycle tracking.\u003c\/p\u003e\n \u003cp\u003eA mid-luteal progesterone above 30 nmol\/L confirms ovulation occurred but doesn't guarantee fertility—many other factors affect conception. Conversely, a lower-than-expected result in one cycle doesn't mean you never ovulate. If you're concerned about fertility, a comprehensive assessment including partner evaluation, fallopian tube assessment, and serial hormone monitoring provides a fuller picture. This test is a useful starting point but should be interpreted as part of a broader fertility investigation when concerns exist.\u003c\/p\u003e\n \u003cp\u003eIf you're experiencing difficulty conceiving, recurrent pregnancy loss, or very irregular cycles, please discuss your results with your GP or a fertility specialist who can interpret them in the context of your full history and recommend appropriate next steps.\u003c\/p\u003e\n \u003c\/div\u003e\n \n\u003c\/div\u003e","brand":"Medi Test Direct","offers":[{"title":"Default Title","offer_id":51607859822922,"sku":"PROG","price":38.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0944\/5926\/5354\/files\/Ovulation_Progesterone_Blood_Test_Kit.png?v=1773302945"},{"product_id":"anti-mullerian-hormone-amh-blood-test-kit","title":"Anti-Müllerian Hormone (AMH) Blood Test Kit","description":"\u003c!-- \nProduct: Anti-Müllerian Hormone (AMH) Blood Test (Home Test Kit)\nCollection: Female Hormones\nCategory: Medical Tests\nWebsite: Meditest\n--\u003e\n\n\u003cdiv class=\"product-listing-container\"\u003e\n \u003cstyle\u003e\n .product-listing-container { font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Helvetica, Arial, sans-serif;

AMH is a hormone produced by the granulosa cells in the small follicles where your eggs develop. Women are born with all the eggs they will ever have (around 1-2 million), and this number naturally declines with age through ovulation and natural loss. As the number of follicles decreases, so does your AMH level, making AMH a reliable marker of your remaining egg supply. This simple finger-prick blood test provides valuable insight into your reproductive health and fertility potential.\u003c\/p\u003e\n \n \u003cp\u003eThis test is ideal for women thinking about starting a family now or in the future, those considering fertility treatments such as IVF or egg freezing, women with a family history of early menopause, anyone experiencing irregular periods who wants to understand their ovarian function, or those simply curious about their egg count. AMH testing is commonly used by fertility specialists to predict response to ovarian stimulation during IVF and to guide treatment decisions. Unlike other reproductive hormones, AMH levels remain relatively stable throughout your menstrual cycle, so this test can be taken at any time.

Each follicle contains an immature egg, and as these follicles grow larger, AMH production stops. Women are born with approximately 1-2 million eggs, and this reserve declines naturally throughout life. By puberty, around 300,000-400,000 eggs remain; by age 30, approximately 25,000; and by menopause, effectively none. Because AMH is produced only by these small ovarian follicles, measuring AMH provides an indirect estimate of your remaining egg supply (ovarian reserve). Higher AMH generally indicates more remaining eggs; lower AMH suggests fewer eggs. AMH levels decline with age, so results must be interpreted relative to your age group. AMH becomes very low or undetectable approximately 5 years before menopause.\u003c\/p\u003e\n \u003cp\u003eAMH testing is particularly valuable in fertility medicine. For women considering IVF or egg freezing, AMH helps predict how well the ovaries will respond to stimulation medications and how many eggs might be retrieved. Women with higher AMH typically respond well to lower medication doses and retrieve more eggs; women with lower AMH may need higher doses and may retrieve fewer eggs. However, AMH measures egg quantity, not egg quality—egg quality is primarily determined by age. A woman with low AMH can still conceive if her remaining eggs are good quality; conversely, normal AMH doesn't guarantee successful pregnancy. Very high AMH levels may indicate polycystic ovary syndrome (PCOS), where multiple small follicles produce elevated AMH. AMH can also help predict timing of menopause—research suggests AMH becomes undetectable approximately 5 years before menopause occurs.

DHEAS (dehydroepiandrosterone sulphate) is the most abundant steroid hormone in the human body and is produced almost exclusively by the adrenal glands. Unlike many hormones that fluctuate throughout the day, DHEAS has a long half-life and relatively stable blood levels, making it an excellent marker of adrenal androgen production. This test provides valuable insight into your adrenal function and can help investigate conditions involving excess or insufficient androgen production.\u003c\/p\u003e\n \n \u003cp\u003eThis test is ideal for women experiencing symptoms of androgen excess such as acne, excess facial or body hair (hirsutism), hair thinning, or irregular periods—where PCOS or adrenal causes need to be investigated. It's also suitable for anyone experiencing symptoms that might suggest adrenal insufficiency (fatigue, weakness, low mood), people interested in monitoring their DHEAS levels as part of an age-related health assessment (since DHEAS naturally declines from around age 30), and those wanting to understand their overall hormonal balance. In clinical practice, DHEAS is often measured alongside other androgens and hormones to build a complete picture.

It's the most abundant circulating steroid hormone in the body and serves as a reservoir or precursor that can be converted into more potent sex hormones including testosterone, dihydrotestosterone (DHT), and oestrogens in various tissues throughout the body. DHEAS is the sulphated (and therefore more stable and longer-lasting) form of DHEA. Because DHEAS comes almost entirely from the adrenal glands (unlike testosterone, which in women comes from both the adrenals and ovaries), it's a useful marker specifically of adrenal androgen production.\u003c\/p\u003e\n \u003cp\u003eDHEAS levels follow a characteristic pattern across the lifespan. Levels are high at birth (due to fetal adrenal activity), fall rapidly in infancy, remain low during childhood, then rise sharply during adrenarche (the maturation of adrenal androgen production, typically around age 6-8, before puberty). DHEAS peaks in early adulthood (around age 20-25) and then gradually declines—by age 70-80, levels are typically only 10-20% of peak values. This age-related decline has led to interest in DHEAS as a marker of biological ageing and 'adrenal reserve,' though the clinical significance of this decline remains debated.\u003c\/p\u003e\n \u003cp\u003eElevated DHEAS can indicate several conditions. In women, elevated DHEAS alongside symptoms like acne, hirsutism (excess hair growth), or irregular periods may suggest Polycystic Ovary Syndrome (PCOS)—though in PCOS the elevation is typically mild to moderate, and very high DHEAS levels should prompt investigation for adrenal tumours or congenital adrenal hyperplasia. In children, elevated DHEAS can indicate premature adrenarche. Low DHEAS may indicate adrenal insufficiency (Addison's disease), hypopituitarism (since the pituitary hormone ACTH stimulates adrenal DHEAS production), or simply reflect the natural decline of ageing. DHEAS is typically interpreted alongside other hormones and clinical context. Results outside the normal range may need a follow-up with your GP or endocrinologist.\u003c\/p\u003e\n \u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003c\/div\u003e\n \u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003c\/div\u003e\n \u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003c!-- Section 7: Medical Disclaimer --\u003e\n \u003cdiv class=\"disclaimer-section\"\u003e\n \u003ch3\u003eMedical Disclaimer\u003c\/h3\u003e\n \u003cp\u003eThis test is for screening and information only—it is not a medical diagnosis or professional advice.

Outside of pregnancy and breastfeeding, prolactin should be present at relatively low levels.

Its name derives from its best-known function—promoting lactation (breast milk production)—but prolactin has over 300 identified functions in the body, affecting reproduction, metabolism, immune function, and behaviour. Prolactin secretion is unique among pituitary hormones: while most are stimulated by hypothalamic releasing hormones, prolactin is under tonic inhibition by dopamine. When dopamine signalling is blocked (by certain medications) or when the pituitary escapes dopamine control (prolactinoma), prolactin rises.\u003c\/p\u003e\n \u003cp\u003eIn non-pregnant, non-breastfeeding women, normal prolactin is typically below 500 mU\/L (or approximately 25 ng\/mL—units vary between laboratories). In men, normal prolactin is typically below 400 mU\/L (approximately 20 ng\/mL). During pregnancy, prolactin rises progressively, reaching 10-20 times normal levels by term. During breastfeeding, each suckling episode triggers a prolactin surge. Levels return to normal within weeks to months after breastfeeding stops.\u003c\/p\u003e\n \u003cp\u003eElevated prolactin (hyperprolactinaemia) has many causes. Physiological causes include pregnancy, breastfeeding, stress, exercise, sleep, nipple stimulation, and high-protein meals. Medications are a very common cause—particularly antipsychotics, which block dopamine receptors (dopamine normally inhibits prolactin). Pathological causes include prolactinoma (a benign pituitary tumour that secretes prolactin, the most common pituitary tumour), other pituitary tumours compressing the stalk (disrupting dopamine delivery), hypothyroidism (high TRH stimulates prolactin), PCOS, chronic kidney disease, and cirrhosis.\u003c\/p\u003e\n \u003cp\u003eThe effects of elevated prolactin relate to its suppression of reproductive hormones. In women, high prolactin inhibits GnRH, reducing FSH and LH, which disrupts ovulation—causing irregular or absent periods, infertility, and low oestrogen (with potential bone loss). It can also cause galactorrhoea (milk discharge) and reduced libido. In men, elevated prolactin suppresses testosterone production, causing erectile dysfunction, reduced libido, infertility, and sometimes gynaecomastia. Both sexes may experience symptoms from a pituitary tumour if present: headaches and visual field defects (particularly loss of peripheral vision from the tumour pressing on the optic chiasm).\u003c\/p\u003e\n \u003cp\u003eThe degree of prolactin elevation helps determine the cause. Mild elevation (500-1000 mU\/L) is often due to medications, stress, or sampling issues—repeat testing is often appropriate. Moderate elevation (1000-5000 mU\/L) warrants investigation for hypothyroidism, medications, or small prolactinomas (microprolactinomas). Very high levels (\u0026gt;5000 mU\/L) are typical of larger prolactinomas (macroprolactinomas) and usually require pituitary MRI imaging. Results outside the normal range may need a follow-up with your GP.\u003c\/p\u003e\n \u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003c\/div\u003e\n \u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003c\/div\u003e\n \u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003c!-- Section 7: Medical Disclaimer --\u003e\n \u003cdiv class=\"disclaimer-section\"\u003e\n \u003ch3\u003eMedical Disclaimer\u003c\/h3\u003e\n \u003cp\u003eProlactin levels fluctuate significantly, and a single elevated result doesn't confirm pathological hyperprolactinaemia. Stress from the blood collection itself can raise prolactin (sometimes called \"stress hyperprolactinaemia\"). If your result is mildly elevated, your doctor may recommend repeat testing under optimal conditions (rested, fasted, relaxed, avoiding all factors that raise prolactin) before proceeding with further investigation. Two or more elevated results are more meaningful than a single reading.\u003c\/p\u003e\n \u003cp\u003eVery rarely, extremely high prolactin from large tumours can cause a laboratory artefact called the \"hook effect,\" where the result appears falsely normal or only mildly elevated. If you have significant symptoms (visual problems, severe headaches, galactorrhoea) but your prolactin seems unexpectedly normal, mention this to your doctor.\u003c\/p\u003e\n \u003cp\u003eIf your prolactin is confirmed to be elevated, further investigation typically includes thyroid function tests (to exclude hypothyroidism as the cause), a detailed medication review, and often pituitary MRI imaging to look for a prolactinoma. Treatment depends on the cause: medication changes if drug-induced, thyroid hormone replacement if hypothyroidism, or dopamine agonist medication (cabergoline or bromocriptine) for prolactinomas—these are very effective at reducing prolactin and shrinking most tumours.

This panel includes three reproductive hormones—follicle-stimulating hormone (FSH), luteinising hormone (LH), and oestradiol—which change predictably during perimenopause and menopause, plus two thyroid markers (TSH and Free T4) because thyroid dysfunction is common in midlife women and can cause symptoms that mimic or overlap with menopause.

In premenopausal women, FSH stimulates the development of ovarian follicles (fluid-filled sacs containing eggs) during the first half of the menstrual cycle. As follicles mature, they produce increasing amounts of oestradiol. A \"feedback loop\" exists: when oestradiol rises sufficiently, it signals the pituitary to reduce FSH production. After ovulation, FSH levels fall and remain low during the second half of the cycle.\u003c\/p\u003e\n \u003cp\u003eAs women approach menopause, the ovaries contain fewer remaining follicles and become less responsive to FSH. The pituitary gland responds by producing more and more FSH in an attempt to stimulate the ovaries—like turning up the thermostat when the heating isn't working. This is why FSH levels rise during perimenopause and menopause. Measuring FSH on day 2-5 of the menstrual cycle provides the most reliable assessment; at other times, levels naturally fluctuate.\u003c\/p\u003e\n \u003cp\u003eIn premenopausal women (day 2-5), FSH is typically 3-10 IU\/L. During perimenopause, FSH begins to rise and often fluctuates unpredictably—it may be elevated one month and normal the next. Persistently elevated FSH above 25-40 IU\/L, particularly when combined with low oestradiol and menstrual changes, suggests the menopausal transition is well underway or complete. FSH above 30-40 IU\/L with amenorrhoea (no periods) for 12 months is consistent with menopause. However, a single FSH measurement cannot definitively \"diagnose\" menopause—the perimenopause is characterised by hormonal variability, and repeat testing may be needed.

In premenopausal women, LH levels remain relatively low during most of the cycle but surge dramatically mid-cycle—this \"LH surge\" triggers ovulation (the release of a mature egg from the ovary). After ovulation, LH stimulates the empty follicle to become the corpus luteum, which produces progesterone to prepare the uterine lining for potential pregnancy.\u003c\/p\u003e\n \u003cp\u003eLike FSH, LH levels rise during perimenopause and menopause as the pituitary attempts to stimulate the increasingly unresponsive ovaries. However, LH typically rises later than FSH and to a lesser degree, so FSH is generally considered the more sensitive marker of ovarian reserve and menopausal status. The FSH:LH ratio can provide additional information—in reproductive-age women, FSH and LH are usually similar (ratio ~1:1), while in menopause, FSH typically exceeds LH.\u003c\/p\u003e\n \u003cp\u003eIn premenopausal women (day 2-5), LH is typically 2-10 IU\/L (with a mid-cycle surge to 20-100+ IU\/L during ovulation). During perimenopause and menopause, baseline LH rises, typically to 15-60 IU\/L. The LH:FSH ratio can sometimes help distinguish menopause from other conditions—for example, in polycystic ovary syndrome (PCOS), LH is often elevated relative to FSH (ratio 2:1 or 3:1), whereas in menopause FSH is typically higher than or equal to LH. LH is interpreted alongside FSH and oestradiol for a complete picture.

It's produced primarily by the ovarian follicles and is responsible for the development and maintenance of female reproductive tissues, breast development, bone health, cardiovascular protection, skin health, and cognitive function. Oestradiol also affects mood, sleep, and libido. In premenopausal women, oestradiol levels vary dramatically across the menstrual cycle—lowest at the start of the cycle, rising as follicles develop, peaking just before ovulation, then fluctuating in the second half.\u003c\/p\u003e\n \u003cp\u003eDuring perimenopause, oestradiol levels become erratic. Early perimenopause may actually see higher-than-normal oestradiol levels on some days as the pituitary pumps out FSH and stimulates remaining follicles. Later perimenopause typically sees declining and inconsistent oestradiol. After menopause, the ovaries essentially stop producing oestradiol, and levels drop to very low—typically below 100 pmol\/L (or \u0026lt;30 pg\/mL). This dramatic oestrogen decline is responsible for most menopausal symptoms including hot flushes, night sweats, vaginal dryness, sleep disturbances, and accelerated bone loss.\u003c\/p\u003e\n \u003cp\u003eIn premenopausal women (day 2-5), oestradiol is typically 100-400 pmol\/L (30-120 pg\/mL). It rises mid-cycle to 400-1500 pmol\/L (120-450 pg\/mL) around ovulation. In postmenopausal women not on HRT, oestradiol is typically below 100 pmol\/L (\u0026lt;30 pg\/mL). The combination of high FSH with low oestradiol is the classic hormonal pattern of menopause. If oestradiol is still elevated, it may mask a high FSH reading (because oestradiol suppresses FSH), so both markers together give a more accurate picture than either alone.

TSH works through a feedback mechanism: when thyroid hormone levels drop, the pituitary releases more TSH to stimulate the thyroid; when thyroid hormone levels rise, TSH production decreases. This makes TSH the most sensitive marker of thyroid function—abnormal TSH is usually the first sign of thyroid dysfunction.\u003c\/p\u003e\n \u003cp\u003eThyroid disorders are significantly more common in women than men and often emerge or worsen around the time of menopause. Importantly, hypothyroidism (underactive thyroid) causes symptoms that closely mimic menopause: fatigue, weight gain, cold intolerance, dry skin, hair thinning, constipation, low mood, and brain fog. Hyperthyroidism (overactive thyroid) can cause anxiety, palpitations, heat intolerance, and irregular periods—also potentially confused with perimenopause. This overlap makes checking thyroid function essential when investigating menopausal symptoms.\u003c\/p\u003e\n \u003cp\u003eNormal TSH is typically 0.4-4.0 mIU\/L, though many laboratories use narrower optimal ranges (0.5-2.5 mIU\/L). Elevated TSH (above 4.0-4.5 mIU\/L) suggests hypothyroidism—the thyroid isn't producing enough hormone, so the pituitary makes more TSH trying to stimulate it. Low TSH (below 0.4 mIU\/L) suggests hyperthyroidism—excess thyroid hormone is suppressing TSH production. Subclinical thyroid disease (mildly abnormal TSH with normal free T4) is common and may still cause symptoms. If your TSH is abnormal, further investigation and treatment may significantly improve your symptoms.

Most T4 in the blood is bound to carrier proteins and is inactive; only the small \"free\" fraction (about 0.03% of total T4) is available to enter cells and exert biological effects. T4 itself is relatively inactive—it's converted to the more active T3 (triiodothyronine) in tissues throughout the body as needed.\u003c\/p\u003e\n \u003cp\u003eFree T4 is measured alongside TSH to confirm and characterise thyroid dysfunction. In primary hypothyroidism (thyroid gland failure), TSH is elevated and free T4 is low—the thyroid simply can't produce enough hormone despite being stimulated. In primary hyperthyroidism (overactive thyroid), TSH is suppressed and free T4 is elevated—excess hormone production is shutting down the pituitary's TSH output.

Menopause is clinically defined as 12 consecutive months without a menstrual period in the absence of other causes—it's a retrospective diagnosis based primarily on symptoms and menstrual history, not blood tests. Hormone levels, particularly during perimenopause, can fluctuate dramatically from month to month, so a single measurement provides a snapshot that may not reflect your overall pattern. Results should be interpreted in the context of your age, symptoms, and menstrual history.\u003c\/p\u003e\n \u003cp\u003eThe NICE guidelines state that FSH testing is not required to diagnose menopause in women over 45 with typical symptoms—the diagnosis can be made clinically. However, hormone testing can be useful for women under 45 with suspected premature menopause (premature ovarian insufficiency), women who've had a hysterectomy and can't use menstrual changes as a guide, and those wanting objective confirmation of their menopausal status. If your results suggest a thyroid problem, this is important to address as thyroid conditions are treatable and treatment can significantly improve symptoms. Please discuss your results with your GP or a menopause specialist who can advise on symptom management, HRT options if appropriate, and any further investigations needed.\u003c\/p\u003e\n \u003c\/div\u003e\n \n\u003c\/div\u003e","brand":"Medi Test Direct","offers":[{"title":"Default Title","offer_id":51599520760138,"sku":"Inuvi ( )","price":68.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0944\/5926\/5354\/files\/Menopause_Blood_Test_Kit.png?v=1773260673"},{"product_id":"oestradiol-blood-test-kit","title":"Oestradiol Blood Home Test Kit","description":"\u003c!-- \nProduct: Oestradiol Blood Test (Home Test Kit)\nCollection: Women's Health \/ Men's Health\nCategory: Medical Tests\nWebsite: Meditest\n--\u003e\n\n\u003cdiv class=\"product-listing-container\"\u003e\n \u003cstyle\u003e\n .product-listing-container { font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Helvetica, Arial, sans-serif;

DO NOT collect your finger-prick sample from any finger that has applied these products in the past 4 weeks, even if you've washed your hands thoroughly. Trace hormone residue on fingertips can cause dramatically elevated results that don't reflect your true blood levels.

For a baseline assessment of ovarian function, collect your sample on day 2, 3, 4, or 5 of your cycle (counting the first day of menstrual bleeding as day 1). This \"early follicular phase\" provides the most consistent baseline. If you're investigating ovulation or mid-cycle levels, your doctor may advise testing around day 12-14. If you no longer have periods or have very irregular cycles, you can test at any time—note this on your request form.\u003c\/p\u003e\n \u003cp\u003e\u003cstrong\u003eHormonal Contraception:\u003c\/strong\u003e Hormonal contraceptives (the pill, patch, ring, hormonal IUD, implant, injection) contain synthetic oestrogens and\/or progestins that suppress your natural hormone production. Your oestradiol level while on these contraceptives won't reflect your natural underlying levels. For a true baseline assessment, you'd need to stop hormonal contraception and wait for natural cycles to resume. If you're testing while on contraception, note this clearly on your request form.\u003c\/p\u003e\n \u003cp\u003e\u003cstrong\u003eHRT Monitoring:\u003c\/strong\u003e If you're on hormone replacement therapy and want to check your levels while on treatment, continue your HRT as prescribed and take your sample at a consistent time relative to your last dose.

In premenopausal women, oestradiol is primarily produced by the ovarian follicles, with smaller amounts from the adrenal glands and fat tissue. It's responsible for the development and maintenance of female reproductive organs, breast development, the menstrual cycle, and the preparation of the uterine lining for pregnancy. Oestradiol also has important effects throughout the body—it helps maintain bone density, supports cardiovascular health, influences skin elasticity and collagen, affects mood and cognitive function, and helps regulate body fat distribution.\u003c\/p\u003e\n \u003cp\u003eIn women, oestradiol levels vary dramatically across the menstrual cycle. During the early follicular phase (days 2-5), levels are at their lowest baseline, typically 100-400 pmol\/L. As the dominant follicle matures, oestradiol rises progressively, peaking at 400-1500 pmol\/L (or higher) just before ovulation—this oestradiol surge triggers the LH surge that causes ovulation. After ovulation, oestradiol levels fall briefly then rise again moderately during the luteal phase before declining if pregnancy doesn't occur. This cyclical variation means that a single oestradiol measurement must be interpreted in the context of when in the cycle it was taken.\u003c\/p\u003e\n \u003cp\u003eAs women approach menopause, oestradiol production becomes erratic. The ovaries contain fewer remaining follicles and produce oestradiol less consistently—some cycles may have near-normal oestradiol, while others are much lower. Eventually, after menopause, the ovaries essentially stop producing oestradiol, and levels drop to very low—typically below 100 pmol\/L (often below 50 pmol\/L). This dramatic decline causes the classic menopausal symptoms: hot flushes, night sweats, vaginal dryness, sleep disturbances, mood changes, and accelerated bone loss. Low oestradiol significantly increases the long-term risk of osteoporosis.\u003c\/p\u003e\n \u003cp\u003eIn men, oestradiol is produced by conversion from testosterone via the enzyme aromatase, which is found in fat tissue, liver, brain, and other tissues. Normal oestradiol in men is typically 40-160 pmol\/L—much lower than in premenopausal women but still essential for health. Adequate oestradiol in men supports bone density, libido, brain function, and cardiovascular health. However, excess oestradiol can cause problems: gynaecomastia (breast tissue growth), reduced libido, erectile dysfunction, emotional changes, and water retention. Men on testosterone replacement therapy need to monitor oestradiol because testosterone can convert to oestradiol—if levels become excessive, treatment adjustments or aromatase inhibitors may be considered. Results outside the normal range may need a follow-up with your GP.\u003c\/p\u003e\n \u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003c\/div\u003e\n \u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003c\/div\u003e\n \u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003c!-- Section 7: Medical Disclaimer --\u003e\n \u003cdiv class=\"disclaimer-section\"\u003e\n \u003ch3\u003eMedical Disclaimer\u003c\/h3\u003e\n \u003cp\u003eA single oestradiol measurement provides a snapshot at one point in time. In premenopausal women, oestradiol varies dramatically across the menstrual cycle, so results must be interpreted in the context of when the sample was taken. For fertility assessment, oestradiol is typically measured on day 2-3 alongside FSH—oestradiol alone provides limited information about ovarian reserve. For HRT monitoring, target ranges vary depending on the type of HRT, route of administration, and individual symptoms—your prescribing doctor can advise on your personal targets.\u003c\/p\u003e\n \u003cp\u003eTransdermal hormone contamination is a common cause of falsely elevated oestradiol results—if your result seems unexpectedly high, consider whether contamination might be responsible and repeat the test with extra precautions.

While often thought of as a \"female hormone,\" oestradiol is essential for health in both men and women—it plays crucial roles in reproductive function, bone health, cardiovascular protection, brain function, and skin health. In women, oestradiol is primarily produced by the ovaries and varies dramatically across the menstrual cycle.

For men, this test is valuable for those on testosterone replacement therapy (TRT) wanting to monitor oestradiol levels, men experiencing symptoms of high oestradiol (gynaecomastia, reduced libido, erectile dysfunction, mood changes), and anyone concerned about oestrogen-related issues affecting their health.\u003c\/p\u003e\n \n \u003cp\u003e\u003cstrong\u003eWhat's covered in the price:\u003c\/strong\u003e Your kit contains everything needed to collect a finger-prick blood sample at home.

DO NOT collect your finger-prick sample from any finger that has applied these products in the past 4 weeks, even if you've washed your hands thoroughly. Trace hormone residue on fingertips can cause dramatically elevated results that don't reflect your true blood levels.

For a baseline assessment of ovarian function, collect your sample on day 2, 3, 4, or 5 of your cycle (counting the first day of menstrual bleeding as day 1). This \"early follicular phase\" provides the most consistent baseline. If you're investigating ovulation or mid-cycle levels, your doctor may advise testing around day 12-14. If you no longer have periods or have very irregular cycles, you can test at any time—note this on your request form.\u003c\/p\u003e\n \u003cp\u003e\u003cstrong\u003eHormonal Contraception:\u003c\/strong\u003e Hormonal contraceptives (the pill, patch, ring, hormonal IUD, implant, injection) contain synthetic oestrogens and\/or progestins that suppress your natural hormone production. Your oestradiol level while on these contraceptives won't reflect your natural underlying levels. For a true baseline assessment, you'd need to stop hormonal contraception and wait for natural cycles to resume. If you're testing while on contraception, note this clearly on your request form.\u003c\/p\u003e\n \u003cp\u003e\u003cstrong\u003eHRT Monitoring:\u003c\/strong\u003e If you're on hormone replacement therapy and want to check your levels while on treatment, continue your HRT as prescribed and take your sample at a consistent time relative to your last dose. For transdermal oestrogen, take extreme care to avoid fingertip contamination—wear gloves when applying and never collect from the application hand. Note your HRT type, dose, and timing of last dose on your request form.\u003c\/p\u003e\n \u003cp\u003e\u003cstrong\u003eFor Men on TRT:\u003c\/strong\u003e If you're on testosterone replacement therapy, oestradiol monitoring is important because testosterone can convert to oestradiol via aromatisation.

In premenopausal women, oestradiol is primarily produced by the ovarian follicles, with smaller amounts from the adrenal glands and fat tissue. It's responsible for the development and maintenance of female reproductive organs, breast development, the menstrual cycle, and the preparation of the uterine lining for pregnancy. Oestradiol also has important effects throughout the body—it helps maintain bone density, supports cardiovascular health, influences skin elasticity and collagen, affects mood and cognitive function, and helps regulate body fat distribution.\u003c\/p\u003e\n \u003cp\u003eIn women, oestradiol levels vary dramatically across the menstrual cycle. During the early follicular phase (days 2-5), levels are at their lowest baseline, typically 100-400 pmol\/L. As the dominant follicle matures, oestradiol rises progressively, peaking at 400-1500 pmol\/L (or higher) just before ovulation—this oestradiol surge triggers the LH surge that causes ovulation. After ovulation, oestradiol levels fall briefly then rise again moderately during the luteal phase before declining if pregnancy doesn't occur. This cyclical variation means that a single oestradiol measurement must be interpreted in the context of when in the cycle it was taken.\u003c\/p\u003e\n \u003cp\u003eAs women approach menopause, oestradiol production becomes erratic. The ovaries contain fewer remaining follicles and produce oestradiol less consistently—some cycles may have near-normal oestradiol, while others are much lower. Eventually, after menopause, the ovaries essentially stop producing oestradiol, and levels drop to very low—typically below 100 pmol\/L (often below 50 pmol\/L). This dramatic decline causes the classic menopausal symptoms: hot flushes, night sweats, vaginal dryness, sleep disturbances, mood changes, and accelerated bone loss. Low oestradiol significantly increases the long-term risk of osteoporosis.\u003c\/p\u003e\n \u003cp\u003eIn men, oestradiol is produced by conversion from testosterone via the enzyme aromatase, which is found in fat tissue, liver, brain, and other tissues. Normal oestradiol in men is typically 40-160 pmol\/L—much lower than in premenopausal women but still essential for health. Adequate oestradiol in men supports bone density, libido, brain function, and cardiovascular health. However, excess oestradiol can cause problems: gynaecomastia (breast tissue growth), reduced libido, erectile dysfunction, emotional changes, and water retention. Men on testosterone replacement therapy need to monitor oestradiol because testosterone can convert to oestradiol—if levels become excessive, treatment adjustments or aromatase inhibitors may be considered. Results outside the normal range may need a follow-up with your GP.\u003c\/p\u003e\n \u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003c\/div\u003e\n \u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003c\/div\u003e\n \u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003c!-- Section 7: Medical Disclaimer --\u003e\n \u003cdiv class=\"disclaimer-section\"\u003e\n \u003ch3\u003eMedical Disclaimer\u003c\/h3\u003e\n \u003cp\u003eA single oestradiol measurement provides a snapshot at one point in time. In premenopausal women, oestradiol varies dramatically across the menstrual cycle, so results must be interpreted in the context of when the sample was taken. For fertility assessment, oestradiol is typically measured on day 2-3 alongside FSH—oestradiol alone provides limited information about ovarian reserve. For HRT monitoring, target ranges vary depending on the type of HRT, route of administration, and individual symptoms—your prescribing doctor can advise on your personal targets.\u003c\/p\u003e\n \u003cp\u003eTransdermal hormone contamination is a common cause of falsely elevated oestradiol results—if your result seems unexpectedly high, consider whether contamination might be responsible and repeat the test with extra precautions.

Day 2-5 of your cycle (with day 1 being the first day of your period) is when these hormones are at their baseline levels before the monthly surge that leads to ovulation, making it the optimal time to assess your underlying reproductive function. This timing is standard practice in fertility clinics worldwide and allows meaningful comparison with established reference ranges.\u003c\/p\u003e\n \n \u003cp\u003eThis test is ideal for women who are thinking about starting a family and want to understand their fertility potential, those who have been trying to conceive and want to check whether their hormone levels are optimal, anyone wanting to assess their ovarian reserve before making decisions about family planning timing, women concerned about early menopause or premature ovarian insufficiency, and those who want baseline fertility information before considering egg freezing or other fertility preservation options. The combination of FSH, LH, and oestradiol provides complementary information—FSH reflects ovarian reserve, the LH:FSH ratio can indicate conditions like PCOS, and oestradiol helps validate that testing was done at the correct cycle stage.

In women, FSH stimulates the growth and maturation of ovarian follicles—the fluid-filled sacs in the ovaries that each contain an egg. During the early follicular phase of your menstrual cycle (days 1-5), FSH levels rise to recruit a cohort of follicles, one of which will become dominant and eventually release a mature egg at ovulation. As the follicles grow, they produce oestradiol, which provides negative feedback to the pituitary to reduce FSH secretion—this is how one dominant follicle is selected while others regress.\u003c\/p\u003e\n \u003cp\u003eDay 3 FSH is one of the most important markers of ovarian reserve—the quantity and quality of eggs remaining in your ovaries. The key principle is that if your ovaries have good reserve (plenty of responsive follicles), relatively little FSH is needed to stimulate follicle growth, so baseline FSH remains low. If ovarian reserve is diminished (fewer remaining follicles or less responsive ovaries), the pituitary must produce more FSH to achieve the same effect, resulting in elevated day 3 FSH. Higher FSH levels on day 3 therefore suggest reduced ovarian reserve. However, FSH alone doesn't tell the whole story—oestradiol levels on the same day help validate the result, and AMH (Anti-Müllerian Hormone, tested separately) provides additional complementary information about ovarian reserve. FSH levels naturally rise as women approach menopause. Results outside the normal range may need a follow-up with your GP or fertility specialist.\u003c\/p\u003e\n \u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003cinput type=\"checkbox\" id=\"meditest-bio-lh-day3\"\u003e\n \u003cdiv class=\"biomarker-item\"\u003e\n \u003clabel for=\"meditest-bio-lh-day3\" class=\"biomarker-header\"\u003e\n \u003cspan class=\"biomarker-name\"\u003eLH (Luteinising Hormone)\u003c\/span\u003e\n \u003cspan class=\"dropdown-icon\"\u003e▼\u003c\/span\u003e\n \u003c\/label\u003e\n \u003cdiv class=\"biomarker-content\"\u003e\n \u003cp\u003eLuteinising Hormone (LH) is produced by the pituitary gland alongside FSH and works in concert with FSH to regulate the menstrual cycle and ovulation. During the early follicular phase, LH levels are relatively low and stable. As oestradiol rises from the growing dominant follicle, it eventually triggers a dramatic surge in LH (the 'LH surge') which causes the mature follicle to rupture and release its egg—this is ovulation. After ovulation, LH helps support the corpus luteum (the remnant of the follicle) to produce progesterone during the luteal phase.\u003c\/p\u003e\n \u003cp\u003eOn day 3 of your cycle, LH should be at its baseline level. The relationship between LH and FSH on day 3 provides additional diagnostic information. In most women, FSH is slightly higher than LH in the early follicular phase, giving an LH:FSH ratio below 1. An elevated LH:FSH ratio (LH higher than FSH, or ratio above 2-3) on day 3 is one of the hormonal features of Polycystic Ovary Syndrome (PCOS), a common condition affecting ovulation and fertility. Women with PCOS often have tonically elevated LH which contributes to the hormonal imbalances and ovulatory dysfunction characteristic of the condition. However, not all women with PCOS show this pattern, and an abnormal ratio alone isn't sufficient for diagnosis—PCOS diagnosis requires additional criteria. Results outside the normal range may need a follow-up with your GP or fertility specialist.\u003c\/p\u003e\n \u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003cinput type=\"checkbox\" id=\"meditest-bio-oestradiol-day3\"\u003e\n \u003cdiv class=\"biomarker-item\"\u003e\n \u003clabel for=\"meditest-bio-oestradiol-day3\" class=\"biomarker-header\"\u003e\n \u003cspan class=\"biomarker-name\"\u003eOestradiol (E2)\u003c\/span\u003e\n \u003cspan class=\"dropdown-icon\"\u003e▼\u003c\/span\u003e\n \u003c\/label\u003e\n \u003cdiv class=\"biomarker-content\"\u003e\n \u003cp\u003eOestradiol (also spelled estradiol, abbreviated E2) is the most potent and abundant form of oestrogen in premenopausal women. It's primarily produced by the growing follicles in the ovaries, with small amounts also produced by the adrenal glands and fat tissue. Oestradiol has wide-ranging effects throughout the body: it maintains the uterine lining, supports bone health, influences cholesterol metabolism, affects mood and cognition, and maintains vaginal and skin health. During the menstrual cycle, oestradiol levels are low at the start, rise steadily as follicles grow (peaking just before ovulation), drop briefly after ovulation, then rise again during the luteal phase before falling if pregnancy doesn't occur.\u003c\/p\u003e\n \u003cp\u003eOn day 3, oestradiol should be at a relatively low baseline level (typically below 200 pmol\/L or 50 pg\/mL). Day 3 oestradiol serves an important role in validating your FSH result. If oestradiol is elevated on day 3 (suggesting you may have tested at the wrong time, or that a follicle has already started growing early), it can suppress FSH through negative feedback—giving a falsely reassuring low FSH even if ovarian reserve is actually reduced. This is why interpreting FSH in isolation can be misleading; the oestradiol provides a quality check. An elevated day 3 oestradiol with a 'normal' FSH should be interpreted with caution. Low day 3 oestradiol combined with high FSH is consistent with diminished ovarian reserve or approaching menopause. Results outside the normal range may need a follow-up with your GP or fertility specialist.\u003c\/p\u003e\n \u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003c\/div\u003e\n \u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003c\/div\u003e\n \u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003c!-- Section 7: Medical Disclaimer --\u003e\n \u003cdiv class=\"disclaimer-section\"\u003e\n \u003ch3\u003eMedical Disclaimer\u003c\/h3\u003e\n \u003cp\u003eThis test is for screening and information only—it is not a medical diagnosis or professional advice.

Before menopause, it's produced primarily by the ovaries and plays essential roles in the menstrual cycle, bone health, cardiovascular protection, brain function, skin health, and vaginal\/urinary tract maintenance. Oestradiol levels fluctuate throughout the menstrual cycle, peaking just before ovulation, and decline significantly during perimenopause and menopause as ovarian function wanes.\u003c\/p\u003e\n \u003cp\u003eLow oestradiol levels are responsible for most menopausal symptoms: hot flushes, night sweats, sleep disturbances, mood changes, vaginal dryness and discomfort, reduced libido, and brain fog. Long-term oestrogen deficiency also increases the risk of osteoporosis (bone thinning) and may affect cardiovascular health. The goal of oestrogen replacement in HRT is to restore oestradiol to levels that relieve symptoms and protect bone health without being excessively high.\u003c\/p\u003e\n \u003cp\u003eWhen monitoring HRT, oestradiol levels help assess whether you're achieving adequate replacement. While there's no single \"optimal\" level (treatment is guided primarily by symptoms), many specialists aim for oestradiol levels in the range of 200-600 pmol\/L for symptom relief and bone protection, though this varies by individual and HRT type. Levels that are persistently low despite HRT may indicate a need for dose adjustment or a different delivery method. If you're using transdermal oestrogen (gels, patches, sprays), sample contamination can cause falsely elevated readings—always wear gloves when applying and avoid using fingers that have touched the product. Results should be discussed with your HRT prescriber who can interpret them in the context of your symptoms and treatment goals.\u003c\/p\u003e\n \u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003cinput type=\"checkbox\" id=\"meditest-bio-progesterone-hrt\"\u003e\n \u003cdiv class=\"biomarker-item\"\u003e\n \u003clabel for=\"meditest-bio-progesterone-hrt\" class=\"biomarker-header\"\u003e\n \u003cspan class=\"biomarker-name\"\u003eProgesterone\u003c\/span\u003e\n \u003cspan class=\"dropdown-icon\"\u003e▼\u003c\/span\u003e\n \u003c\/label\u003e\n \u003cdiv class=\"biomarker-content\"\u003e\n \u003cp\u003eProgesterone is a steroid hormone produced by the corpus luteum (the remnant of the ovarian follicle after ovulation) during the second half of the menstrual cycle, and by the placenta during pregnancy. It prepares and maintains the uterine lining (endometrium) for potential pregnancy. After menopause, when ovulation no longer occurs, progesterone production drops to very low levels.\u003c\/p\u003e\n \u003cp\u003eIn HRT, progesterone (or a synthetic progestogen) is an essential component for any woman who still has her uterus. Oestrogen alone causes the endometrial lining to thicken continuously, which over time significantly increases the risk of endometrial hyperplasia and endometrial cancer. Progesterone opposes this effect, causing regular shedding (in cyclical regimens) or keeping the lining thin (in continuous combined regimens), thereby protecting against endometrial cancer. Women who have had a hysterectomy do not need progesterone with their HRT.\u003c\/p\u003e\n \u003cp\u003eWhen monitoring HRT, progesterone levels help confirm that adequate endometrial protection is being achieved. The interpretation depends on your HRT regimen—cyclical (where progesterone is taken for part of the month) or continuous combined (where progesterone is taken every day). For those on micronised progesterone (body-identical progesterone such as Utrogestan), blood levels can be measured to confirm absorption and adequate dosing. Synthetic progestogens may not be accurately reflected in a progesterone blood test. Note on your request form what type of progesterone\/progestogen you're taking and when you last took it. Results should be discussed with your HRT prescriber.\u003c\/p\u003e\n \u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003cinput type=\"checkbox\" id=\"meditest-bio-fsh-hrt\"\u003e\n \u003cdiv class=\"biomarker-item\"\u003e\n \u003clabel for=\"meditest-bio-fsh-hrt\" class=\"biomarker-header\"\u003e\n \u003cspan class=\"biomarker-name\"\u003eFSH (Follicle Stimulating Hormone)\u003c\/span\u003e\n \u003cspan class=\"dropdown-icon\"\u003e▼\u003c\/span\u003e\n \u003c\/label\u003e\n \u003cdiv class=\"biomarker-content\"\u003e\n \u003cp\u003eFollicle Stimulating Hormone (FSH) is produced by the pituitary gland in the brain and plays a crucial role in the reproductive system. In women, FSH stimulates the growth and development of ovarian follicles, each of which contains an egg. FSH levels vary throughout the menstrual cycle, rising in the first half to stimulate follicle development and then dropping after ovulation.\u003c\/p\u003e\n \u003cp\u003eAs women approach and enter menopause, FSH levels rise progressively. This occurs because the ovaries become less responsive to FSH stimulation, so the pituitary gland produces more FSH in an attempt to stimulate the ovaries—a classic negative feedback loop. Persistently elevated FSH (typically above 25-40 IU\/L) combined with low oestradiol and absent periods is consistent with menopause. During perimenopause, FSH levels fluctuate considerably and may not always be elevated.\u003c\/p\u003e\n \u003cp\u003eWhen taking HRT, FSH levels can provide useful information but require careful interpretation. Oestrogen replacement typically causes FSH to fall (as the pituitary senses adequate oestrogen and reduces its stimulation signal), though it may not return to premenopausal levels. A persistently very high FSH despite HRT could suggest inadequate oestrogen replacement, though the clinical picture (symptoms) is more important than targeting a specific FSH number. FSH is most useful as part of the overall picture alongside oestradiol levels and your symptom response.

This makes it useful for detecting chronic low-grade inflammation that might not show up on a standard CRP test.\u003c\/p\u003e\n \u003cp\u003eChronic inflammation is increasingly recognised as a contributor to fatigue. Inflammatory cytokines (the signalling molecules that trigger CRP production) directly affect the brain, causing symptoms that collectively resemble fatigue: low energy, reduced motivation, poor concentration, disturbed sleep, and mood changes. This \"sickness behaviour\" is an evolved response to infection but can become problematic when inflammation persists without an acute infection. Conditions associated with chronic low-grade inflammation include obesity, poor metabolic health, autoimmune conditions, chronic infections, and some mood disorders.\u003c\/p\u003e\n \u003cp\u003eNormal hs-CRP is generally below 3 mg\/L, with lower levels (\u0026lt;1 mg\/L) being optimal.

Iron is essential for making haemoglobin (the oxygen-carrying protein in red blood cells) and myoglobin (the equivalent protein in muscles), as well as for numerous enzymes involved in energy production, DNA synthesis, and other vital functions. Without adequate iron, cells cannot produce energy efficiently, leading to fatigue.\u003c\/p\u003e\n \u003cp\u003eSerum iron on its own is difficult to interpret because it fluctuates significantly throughout the day, in response to recent meals (particularly iron-rich foods), and due to many other factors. A single low serum iron reading doesn't necessarily mean iron deficiency, and a normal reading doesn't rule it out. This is why serum iron is always interpreted alongside other iron markers (TIBC, transferrin saturation, and ferritin) to get a complete picture of iron status.\u003c\/p\u003e\n \u003cp\u003eNormal serum iron is typically 10-30 µmol\/L, though ranges vary between laboratories. Low serum iron with high TIBC, low transferrin saturation, and low ferritin indicates iron deficiency.

TIBC is an indirect measure of transferrin levels: the more transferrin available, the higher the iron-binding capacity.\u003c\/p\u003e\n \u003cp\u003eYour body regulates transferrin production based on iron status. When iron stores are low, the liver produces more transferrin to maximise iron capture and transport from the diet—so TIBC increases.

This makes TIBC a useful indicator of iron stores when interpreted alongside serum iron and ferritin.\u003c\/p\u003e\n \u003cp\u003eNormal TIBC is typically 45-80 µmol\/L. High TIBC (with low serum iron and low ferritin) strongly suggests iron deficiency—the body is ramping up its iron transport capacity because stores are depleted. Low TIBC may be seen in iron overload (haemochromatosis), chronic inflammation, liver disease, or malnutrition.

It's calculated by dividing serum iron by TIBC and multiplying by 100. This ratio provides a snapshot of how much iron is actually being transported relative to the maximum capacity available.\u003c\/p\u003e\n \u003cp\u003eNormal transferrin saturation is typically 20-50%. Low transferrin saturation (below 20%) indicates that less iron is being transported than the body's capacity allows—this is typical of iron deficiency. Very low transferrin saturation (\u0026lt;15-16%) strongly suggests iron deficiency and correlates with impaired iron delivery to tissues, even before anaemia develops. High transferrin saturation (above 45-50%) suggests iron overload—more iron is being transported than is healthy. Very high saturation (\u0026gt;60%) is concerning for haemochromatosis and warrants further investigation.\u003c\/p\u003e\n \u003cp\u003eTransferrin saturation is particularly useful because it can detect both iron deficiency and iron overload.

It holds iron in a soluble, non-toxic form in cells throughout the body (particularly the liver, spleen, and bone marrow) and releases it when needed.

Even ferritin levels that are technically \"within range\" but at the lower end (e.g., 15-30 µg\/L) may be associated with fatigue symptoms, particularly in menstruating women. Many practitioners now aim for ferritin levels of at least 50 µg\/L in patients with fatigue symptoms, as this is associated with better energy and exercise tolerance, particularly in athletes and those with heavy periods.\u003c\/p\u003e\n \u003cp\u003eNormal ferritin ranges are typically 15-300 µg\/L for men and 15-200 µg\/L for women, but optimal levels for wellbeing may be higher. However, ferritin is an acute phase reactant—it rises during inflammation, infection, and liver disease—so a \"normal\" ferritin in the context of illness doesn't rule out underlying iron deficiency.

TSH levels reflect the body's assessment of thyroid hormone status: when thyroid hormones are low, TSH rises to stimulate more production; when thyroid hormones are high, TSH falls to slow production. This feedback loop makes TSH the most sensitive initial marker for thyroid dysfunction.\u003c\/p\u003e\n \u003cp\u003eAn elevated TSH indicates that the thyroid is underperforming (hypothyroidism)—the pituitary is working harder to stimulate a sluggish thyroid. Hypothyroidism is a very common cause of fatigue, affecting around 2% of the UK population (more common in women and with increasing age). Other symptoms include weight gain, feeling cold, constipation, dry skin, hair loss, and depression. A low TSH indicates that the thyroid is overactive (hyperthyroidism)—the pituitary is backing off because thyroid hormones are already high. Hyperthyroidism can also cause fatigue, along with weight loss, anxiety, tremor, palpitations, and heat intolerance.\u003c\/p\u003e\n \u003cp\u003eNormal TSH is typically 0.4-4.0 mU\/L, though \"optimal\" may be narrower (0.5-2.5 mU\/L). Mildly elevated TSH (4-10 mU\/L) is termed \"subclinical hypothyroidism\" and may or may not require treatment depending on symptoms and other factors. TSH should be interpreted alongside Free T4 for a complete picture. Results outside the normal range may need a follow-up with your GP.\u003c\/p\u003e\n \u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003cinput type=\"checkbox\" id=\"meditest-bio-ft4-fatigue\"\u003e\n \u003cdiv class=\"biomarker-item\"\u003e\n \u003clabel for=\"meditest-bio-ft4-fatigue\" class=\"biomarker-header\"\u003e\n \u003cspan class=\"biomarker-name\"\u003eFree T4 (Free Thyroxine)\u003c\/span\u003e\n \u003cspan class=\"dropdown-icon\"\u003e▼\u003c\/span\u003e\n \u003c\/label\u003e\n \u003cdiv class=\"biomarker-content\"\u003e\n \u003cp\u003eFree T4 (free thyroxine) measures the unbound, biologically active portion of the thyroid hormone thyroxine. Most T4 in blood is bound to proteins and inactive; only the \"free\" fraction (about 0.03%) is available to enter cells and exert effects. T4 is the main hormone produced by the thyroid gland, though it must be converted to the more active T3 (triiodothyronine) within cells to have its full effect.\u003c\/p\u003e\n \u003cp\u003eT4 is the body's main metabolic regulator—it affects virtually every tissue and increases overall metabolic rate, heat production, heart rate, protein synthesis, and energy levels. Low Free T4 (with high TSH) confirms hypothyroidism and explains fatigue through reduced cellular metabolism. High Free T4 (with low TSH) confirms hyperthyroidism. In central hypothyroidism (rare), both TSH and Free T4 are low due to pituitary or hypothalamic problems.\u003c\/p\u003e\n \u003cp\u003eNormal Free T4 is typically 9-25 pmol\/L. Interpreting Free T4 requires considering TSH alongside it: a low-normal Free T4 with a high TSH suggests early or subclinical hypothyroidism. Free T4 in the \"normal\" range doesn't necessarily mean thyroid function is optimal—some individuals feel better with Free T4 in the upper half of the reference range.

The liver converts this to 25-hydroxyvitamin D (25-OH vitamin D), which is the main circulating form and the best indicator of overall vitamin D status. This is the form measured in blood tests. Vitamin D plays crucial roles beyond bone health: it affects muscle function, immune regulation, mood, and energy metabolism.\u003c\/p\u003e\n \u003cp\u003eVitamin D deficiency is extremely common in the UK due to limited sunlight exposure, particularly from October to March when UVB radiation is insufficient for vitamin D synthesis regardless of time spent outdoors. People with darker skin, those who cover their skin for cultural or religious reasons, and people who spend little time outdoors are at particular risk. Symptoms of deficiency include fatigue, muscle weakness, muscle aches, bone pain, frequent infections, and low mood. Many people have no obvious symptoms despite significant deficiency.\u003c\/p\u003e\n \u003cp\u003eVitamin D status is classified as: deficient (\u0026lt;25 nmol\/L), insufficient (25-50 nmol\/L), adequate (50-75 nmol\/L), and optimal (\u0026gt;75 nmol\/L). For those with fatigue, aiming for levels above 75 nmol\/L may be beneficial. UK guidelines recommend that everyone consider taking a vitamin D supplement (10 µg\/400 IU daily) during autumn and winter; those at risk of deficiency should supplement year-round.

It's the hormone that drives your menstrual cycle—stimulating the growth of the uterine lining, triggering the release of LH that causes ovulation, and supporting egg development in the follicles. Oestradiol levels fluctuate dramatically throughout your cycle: they're low during your period, rise as follicles develop, peak just before ovulation, then rise again in the luteal phase. When measured on days 2-5 of your cycle (the follicular phase), oestradiol should be relatively low. Higher-than-expected levels at this time might suggest a cyst, early follicle development, or diminishing ovarian reserve where remaining follicles are working harder. Low levels might indicate ovarian dysfunction or perimenopause.

Early in your cycle, FSH rises to recruit follicles; as the dominant follicle produces oestradiol, this feeds back to reduce FSH. When measured on days 2-5, FSH gives insight into your ovarian reserve. If your ovaries have fewer eggs remaining, they produce less inhibin B (a hormone that suppresses FSH), so FSH levels rise—your pituitary is working harder to stimulate follicle growth. Elevated FSH suggests diminished ovarian reserve or approaching menopause. Very low FSH might indicate pituitary problems or that something is suppressing your hypothalamic-pituitary axis.

Throughout most of your cycle, LH stays relatively low, but when oestradiol from the dominant follicle reaches a threshold, it triggers a massive LH surge—this causes the follicle to rupture and release the egg within 24-36 hours. After ovulation, LH supports the corpus luteum (the remains of the follicle) in producing progesterone. When measured on days 2-5, LH should be similar to or slightly lower than FSH. An elevated LH:FSH ratio (often 2:1 or 3:1) is a characteristic finding in polycystic ovary syndrome (PCOS), where multiple small follicles produce excess LH-stimulating signals.

In women, most testosterone is bound to proteins and inactive; only a small 'free' fraction is biologically active. Elevated testosterone in women is one of the hallmark findings in PCOS and can cause symptoms like acne, excess facial or body hair (hirsutism), and irregular periods. Very high testosterone might indicate an androgen-producing tumour. Low testosterone can contribute to low libido, fatigue, and reduced wellbeing, though it's less commonly tested for in women.

Elevated DHEA-S points specifically to adrenal androgen excess rather than ovarian, which helps distinguish between different causes of high testosterone. It can be elevated in PCOS (though ovarian androgens are usually more prominent), congenital adrenal hyperplasia, and adrenal tumours. DHEA-S naturally peaks in your 20s and gradually declines with age. Low levels are generally less concerning but can contribute to fatigue.

Elevated prolactin (hyperprolactinaemia) suppresses the release of GnRH from the hypothalamus, which in turn reduces FSH and LH, disrupting ovulation and causing irregular or absent periods. This is why breastfeeding can act as a natural contraceptive. Outside of pregnancy and breastfeeding, elevated prolactin can be caused by pituitary adenomas (usually benign), certain medications (especially antipsychotics and some antidepressants), hypothyroidism, and stress. Prolactin is highly sensitive to stress, sleep, nipple stimulation, and even the stress of blood collection—which is why it's important to test in the morning, at least an hour after waking, in a relaxed state.

Even subclinical hypothyroidism—where TSH is elevated but thyroid hormones are still normal—has been associated with difficulty conceiving and increased miscarriage risk. Most fertility specialists aim for TSH below 2.5 mIU\/L when trying to conceive, which is tighter than the general population reference range.

Low Free T4 with high TSH confirms hypothyroidism; high Free T4 with low TSH confirms hyperthyroidism.

Higher AMH suggests a larger ovarian reserve; lower AMH indicates fewer remaining eggs. AMH naturally declines with age as your follicle pool diminishes. Very low AMH doesn't mean you can't conceive naturally—it means your window may be shorter and you may have fewer eggs available for IVF if needed. Very high AMH (often with high antral follicle count) can indicate PCOS.

If you're feeling exhausted despite getting enough sleep, there may be an underlying reason that's easy to identify and treat. This test checks three key areas: thyroid function (an underactive thyroid is one of the most common causes of fatigue), vitamin B12 (essential for energy production and nerve function), and vitamin D (deficiency is extremely common in the UK and frequently causes tiredness and low mood).\u003c\/p\u003e\n \n \u003cp\u003eThis test is ideal for anyone experiencing persistent fatigue that doesn't improve with rest, people who feel tired all the time despite adequate sleep, those who want a quick and affordable check of the most common treatable causes of low energy, and anyone who suspects their tiredness might have a medical cause rather than just being 'run down.' All three conditions tested for—hypothyroidism, B12 deficiency, and vitamin D deficiency—are common, often missed, and readily treatable once identified.

It works as part of a feedback loop: when thyroid hormone levels are low, the pituitary releases more TSH to stimulate the thyroid to produce more; when thyroid levels are adequate, TSH production decreases. TSH is therefore the most sensitive initial marker of thyroid dysfunction—it often becomes abnormal before the thyroid hormones themselves move out of range, making it an excellent screening test.\u003c\/p\u003e\n \u003cp\u003eHigh TSH indicates the pituitary is working harder because thyroid hormone levels are low (hypothyroidism, or underactive thyroid). Hypothyroidism is one of the most common causes of persistent fatigue, affecting about 2% of the UK population and being more common in women and with increasing age. Other symptoms include weight gain, feeling cold, constipation, dry skin, hair loss, and mental sluggishness or 'brain fog.' The good news is that hypothyroidism is easily treatable with thyroid hormone replacement (levothyroxine), and most people feel significantly better once their levels are optimised. Low TSH suggests thyroid hormone levels are too high (hyperthyroidism), which causes different symptoms including anxiety, tremor, and weight loss.

Vitamin B12 is essential for energy production at the cellular level, red blood cell formation, DNA synthesis, and proper nerve function. It's one of the most common vitamin deficiencies and is frequently under-diagnosed because symptoms develop gradually.\u003c\/p\u003e\n \u003cp\u003eB12 deficiency causes fatigue that can be profound—along with other symptoms including weakness, breathlessness, pins and needles or numbness in hands and feet, balance problems, cognitive difficulties ('brain fog'), mood changes, and a sore tongue. If left untreated, B12 deficiency can cause permanent nerve damage, so early identification is important. Risk factors include vegetarian\/vegan diet (B12 is found almost exclusively in animal products), older age (reduced absorption), pernicious anaemia (an autoimmune condition), metformin use, and certain gastrointestinal conditions. The good news is that B12 deficiency is easily treated with supplements or injections, and most people notice improvement in energy levels within weeks of starting treatment.

Despite being called a vitamin, it functions as a hormone and the body produces it when skin is exposed to UVB sunlight. However, in the UK, sun exposure is insufficient during autumn and winter months (October to March) to produce adequate vitamin D, making deficiency extremely common—some estimates suggest up to 1 in 5 UK adults are deficient.\u003c\/p\u003e\n \u003cp\u003eVitamin D deficiency commonly causes fatigue, muscle weakness and aches, bone pain, and low mood—symptoms that are often attributed to 'just being tired' or 'feeling run down' when there's actually a treatable cause. People at higher risk include those with limited sun exposure (office workers, those who cover their skin, housebound individuals), people with darker skin (more melanin reduces vitamin D production), older adults, and those who are overweight. Levels below 25 nmol\/L indicate deficiency; 25-50 nmol\/L is insufficient; above 50 nmol\/L is adequate; and above 75 nmol\/L is considered optimal by many experts.

HDL below 1.0 mmol\/L in men or 1.2 mmol\/L in women is considered a cardiovascular risk factor. Regular aerobic exercise is one of the most effective ways to raise HDL, along with maintaining a healthy weight, moderate alcohol consumption, and eating healthy fats (olive oil, nuts, oily fish). Smoking lowers HDL, providing another reason to quit.

When you eat, your body converts calories it doesn't need immediately into triglycerides, which are stored in fat cells and released between meals for energy. Triglycerides are transported in the blood within VLDL particles produced by the liver.\u003c\/p\u003e\n \u003cp\u003eElevated triglycerides are associated with increased cardiovascular risk and are a component of metabolic syndrome. High levels often indicate excessive calorie intake (particularly from refined carbohydrates, sugars, and alcohol), insulin resistance, or diabetes. They're also elevated in hypothyroidism, kidney disease, and with certain medications. Very high triglycerides (above 10 mmol\/L) can cause pancreatitis.

Vitamin D is unique—it functions more like a hormone than a vitamin and affects nearly every tissue in the body. It's essential for calcium absorption and bone health, but also plays important roles in immune function, muscle function, mood regulation, and cardiovascular health. The body produces vitamin D when skin is exposed to UVB sunlight, with dietary sources (oily fish, fortified foods, egg yolks) providing smaller amounts.\u003c\/p\u003e\n \u003cp\u003eVitamin D deficiency is extremely common in the UK due to limited sunlight, particularly from October to March when UVB levels are insufficient for vitamin D synthesis. Public Health England recommends everyone consider supplementing during autumn and winter. Levels below 25 nmol\/L indicate deficiency, 25-50 nmol\/L indicates insufficiency, and above 50 nmol\/L is considered adequate by most guidelines, though many experts suggest optimal levels are 75-100 nmol\/L. Risk factors for deficiency include limited sun exposure, darker skin, older age, obesity, and covering the skin for cultural or religious reasons. Severe deficiency causes rickets in children and osteomalacia in adults.

Each month, FSH stimulates a cohort of follicles to grow, with usually one becoming dominant and releasing an egg at ovulation. In PCOS, FSH levels are typically normal or slightly low—it's the relationship between FSH and LH that's abnormal. The classic PCOS pattern shows an elevated LH:FSH ratio (often greater than 2:1 or 3:1), reflecting disrupted signalling between the brain and ovaries. This hormonal imbalance contributes to the failure of follicles to develop properly and ovulate, leading to irregular periods and fertility difficulties. FSH alone isn't diagnostic but helps complete the hormonal picture.

LH also stimulates the theca cells in your ovaries to produce androgens (male hormones like testosterone). In PCOS, LH is often elevated, particularly relative to FSH. This elevated LH drives excess androgen production by the ovaries, contributing to symptoms like acne, hirsutism (excess hair growth), and disrupted ovulation. The elevated LH:FSH ratio (typically \u0026gt;2:1) is a characteristic finding in PCOS, though not all women with PCOS show this pattern.

It regulates the menstrual cycle, develops the uterine lining for potential pregnancy, and maintains bone density, skin health, and cardiovascular function. In a normal cycle, oestradiol rises as follicles develop, peaks just before ovulation, and has a secondary rise in the luteal phase. In PCOS, oestradiol levels are often relatively stable rather than showing normal cyclical variation—this reflects the lack of proper follicle development and ovulation. Chronic oestrogen exposure without the balancing effect of progesterone (which requires ovulation) can increase the risk of endometrial hyperplasia.

It's commonly used as a marker of ovarian reserve (how many eggs you have left), but in PCOS, it has a different significance. Women with PCOS typically have elevated AMH—often 2-4 times normal levels—because they have an increased number of small antral follicles in their ovaries (the 'polycystic' appearance on ultrasound). These follicles produce AMH but fail to develop into mature, ovulating follicles. AMH above 35 pmol\/L is increasingly being used as a diagnostic criterion for PCOS in some guidelines. Unlike other hormones, AMH is relatively stable throughout the menstrual cycle and can be measured on any day. Very high AMH can also indicate how severely affected ovarian function is.

The excess testosterone comes mainly from the ovaries, driven by elevated LH, but the adrenal glands can also contribute.

Iron is essential for making haemoglobin (which carries oxygen to your tissues), producing energy in mitochondria, and supporting immune function and brain chemistry. Low iron directly causes fatigue by reducing oxygen delivery and impairing cellular energy production. Serum iron fluctuates throughout the day (highest in the morning) and is affected by recent meals, so it's best interpreted alongside ferritin, TIBC, and transferrin saturation for the complete picture. Low iron with high TIBC and low ferritin confirms iron deficiency. Low iron can occur even when haemoglobin is still normal—you don't have to be anaemic to have symptomatic iron deficiency.

When your iron stores are low, your body produces more transferrin to maximise iron capture from your diet, so TIBC rises. When iron stores are adequate or high, less transferrin is needed and TIBC is normal or low. High TIBC is a hallmark of iron deficiency—your body is ramping up transport capacity to compensate for low stores. Low TIBC can occur with iron overload, chronic disease, or malnutrition.

Low transferrin saturation (below 20%) is a sensitive marker of iron deficiency—there isn't enough iron to fill the available transport. This can cause fatigue even before haemoglobin drops into the anaemic range.

Normal haematocrit is roughly 40-50% in men and 36-44% in women. Low haematocrit, like low haemoglobin, indicates anaemia—your blood has fewer oxygen-carrying cells relative to its volume. Haematocrit can also be affected by hydration status: dehydration concentrates the blood and raises haematocrit artificially, while overhydration dilutes it. Very high haematocrit increases blood viscosity and cardiovascular risk. Haematocrit and haemoglobin generally move together and tell a similar story about your red cell status.

Red cells are produced in your bone marrow and live for about 120 days before being recycled. Low red cell count contributes to anaemia—fewer cells mean less oxygen-carrying capacity. The count, combined with haemoglobin and haematocrit, helps characterise your anaemia. Sometimes red cell count is low while haemoglobin per cell is normal (fewer cells, normal cells); sometimes count is normal but each cell has less haemoglobin than it should. The red cell indices (MCV, MCH, MCHC) help distinguish these patterns and point toward the underlying cause.

Normal MCV is approximately 80-100 fL. This is one of the most important markers for classifying anaemia and determining its cause. Low MCV (microcytic, small cells) typically indicates iron deficiency or thalassaemia—the cells are small because there isn't enough haemoglobin to fill them. High MCV (macrocytic, large cells) suggests vitamin B12 or folate deficiency, alcohol excess, liver disease, hypothyroidism, or certain medications—the cells are larger than normal due to impaired DNA synthesis during production. Normal MCV with low haemoglobin (normocytic anaemia) suggests chronic disease, acute blood loss, or bone marrow problems. MCV is key to directing further investigation.

Normal MCH is approximately 27-32 pg. MCH generally tracks with MCV—small cells (low MCV) have less haemoglobin (low MCH), and large cells (high MCV) have more haemoglobin (high MCH). Low MCH is seen in iron deficiency anaemia and thalassaemia—each cell is carrying less oxygen than it should. High MCH occurs in B12 or folate deficiency where cells are abnormally large.

Low MCHC (hypochromic cells) indicates cells that are pale because they don't have enough haemoglobin relative to their volume—classic in iron deficiency. MCHC is rarely high, but can occur in conditions like hereditary spherocytosis where cells are abnormally shaped and concentrated.

Normal RDW is approximately 11-15%. A high RDW means your cells vary significantly in size (anisocytosis), which typically indicates active production of new cells of different sizes or destruction of cells at different rates. Elevated RDW is common in iron deficiency anaemia (where new cells are smaller than old cells as iron runs out), B12\/folate deficiency, and mixed deficiencies. It can help distinguish between conditions: iron deficiency typically has high RDW, while thalassaemia trait often has normal RDW despite small cells. RDW also has value as a general health marker—elevated RDW is associated with increased cardiovascular risk and mortality, possibly reflecting underlying inflammation or nutritional deficiencies.

It works in a feedback loop—when thyroid hormones are low, TSH rises to stimulate more production; when thyroid hormones are high, TSH drops. This makes TSH the most sensitive single marker for thyroid dysfunction. Hypothyroidism (underactive thyroid) is one of the most common causes of fatigue—it slows your metabolism, leaving you tired, cold, constipated, and mentally foggy. High TSH indicates hypothyroidism; your pituitary is calling for more hormone because levels are low. Low TSH indicates hyperthyroidism, which causes different symptoms including anxiety, tremor, and weight loss, though fatigue can still occur.

T4 circulates in your blood and gets converted to the more active T3 in your tissues as needed. Measuring Free T4 alongside TSH helps confirm and characterise thyroid dysfunction. High TSH with low Free T4 confirms overt hypothyroidism. High TSH with normal Free T4 is subclinical hypothyroidism—your thyroid is struggling but still managing to produce enough hormone for now; this can still cause fatigue and often progresses over time. Low TSH with high Free T4 confirms hyperthyroidism. The combination of TSH and Free T4 together gives a clearer picture than either alone.

It works closely with vitamin B12—deficiency in either causes similar problems. Low folate causes fatigue directly, and can cause macrocytic anaemia (large, immature red blood cells that don't carry oxygen efficiently). Folate deficiency can occur with poor dietary intake (it's found in leafy greens, legumes, and fortified foods), alcohol excess, certain medications (particularly methotrexate and some anti-epileptics), and malabsorption conditions like coeliac disease. Serum folate reflects recent intake over days to weeks.

Deficiency causes fatigue, weakness, neurological symptoms (numbness, tingling, balance problems), cognitive impairment, and macrocytic anaemia. B12 deficiency is common—it affects vegetarians and vegans (B12 is only found naturally in animal products), people over 60 (absorption decreases with age), those with pernicious anaemia (autoimmune destruction of cells needed for B12 absorption), and people taking metformin or proton pump inhibitors long-term.

When there's too much, it can deposit in artery walls, forming plaques that narrow blood vessels over time—this is why it's often called \"bad\" cholesterol.

A lower ratio is better—ideally below 4, with below 3.5 considered optimal. The ratio captures the balance between \"good\" and \"bad\" cholesterol in a single number.

Most uric acid dissolves in blood, passes through the kidneys, and leaves in urine. When levels are too high (hyperuricaemia), crystals can form in joints causing gout—intensely painful inflammatory arthritis, often affecting the big toe. High uric acid also increases kidney stone risk. Purine-rich foods (organ meats, shellfish, beer) and fructose can elevate levels. Some people have genetic tendencies toward high uric acid.

Low platelet counts (thrombocytopenia) increase bleeding risk and can result from viral infections, autoimmune conditions, medications, or bone marrow problems. High counts (thrombocytosis) may be reactive (due to inflammation, infection, or iron deficiency) or indicate a bone marrow disorder. Exercise doesn't significantly affect platelet counts.

Larger platelets are generally younger and more reactive—they contain more granules and are more effective at clotting. High MPV with low platelet count suggests the bone marrow is working hard to replace destroyed platelets (as in immune thrombocytopenia). Low MPV with low platelets suggests bone marrow isn't producing enough. MPV can also be elevated in cardiovascular disease and diabetes.

The detailed breakdown in this panel shows the full picture. Generally, total cholesterol below 5 mmol\/L is considered desirable for most adults.

This process is a major contributor to heart attacks and strokes. Before menopause, women tend to have lower LDL than men due to the protective effects of oestrogen—but after menopause, LDL often rises, and cardiovascular risk increases.

High MCV (macrocytic, large cells) suggests B12 or folate deficiency, alcohol excess, liver disease, or hypothyroidism. Normal MCV with low haemoglobin (normocytic anaemia) can indicate chronic disease, acute blood loss, or bone marrow problems. MCV is one of the most useful markers for directing further investigation when anaemia is found.

Some people have difficulty converting T4 to T3, which can cause persistent hypothyroid symptoms despite normal TSH and T4.

When thyroid hormones in the blood are low, the pituitary releases more TSH to stimulate the thyroid gland to produce more. When thyroid hormone levels are high, the pituitary produces less TSH to slow production. For people taking levothyroxine, TSH is the primary marker used to assess whether the medication dose is correct. A high TSH suggests the dose may be too low (underreplacement), while a suppressed TSH may indicate the dose is too high (overreplacement). Most people on levothyroxine aim for a TSH somewhere between 0.5 and 2.5 mU\/L, though your target may differ based on individual circumstances.

Most T4 in the blood is bound to proteins; only the \"free\" portion is available to enter cells and exert metabolic effects. For people on levothyroxine, FT4 levels help confirm adequate replacement alongside TSH. Ideally, FT4 should sit in the upper half of the reference range when TSH is well-controlled. Low FT4 with high TSH confirms underreplacement; high FT4 with suppressed TSH suggests overreplacement. Some people feel best with FT4 toward the top of the range, while others do well mid-range—optimal levels vary between individuals.

T4 circulates in blood and is converted to the more active T3 in tissues as needed. Measuring Free T4 alongside TSH confirms and characterises thyroid dysfunction. High TSH with low Free T4 confirms overt hypothyroidism—the thyroid isn't producing enough hormone. High TSH with normal Free T4 is subclinical hypothyroidism—the thyroid is struggling but managing to maintain adequate hormone output. Low TSH with high Free T4 confirms hyperthyroidism—the thyroid is overactive. Free T4 is also used to monitor thyroid hormone replacement (levothyroxine) therapy. Thyroid function during pregnancy has particular importance as thyroid hormones are essential for foetal brain development.

Under normal circumstances, thyroglobulin doesn't enter the bloodstream in significant amounts. When the thyroid is inflamed or under autoimmune attack, thyroglobulin can be released and the immune system may produce antibodies against it. Elevated thyroglobulin antibodies indicate autoimmune thyroid disease—either Hashimoto's thyroiditis (which causes hypothyroidism) or Graves' disease (which causes hyperthyroidism). Autoimmune thyroid disease is much more common in women than men. Importantly, elevated thyroid antibodies are associated with an increased risk of miscarriage and pregnancy complications, even when thyroid hormone levels are normal.

TPO antibodies are produced when the immune system mistakenly attacks this enzyme. Elevated TPO antibodies are the most common marker of autoimmune thyroid disease and are found in the majority of people with Hashimoto's thyroiditis and many with Graves' disease. Some people have elevated TPO antibodies but normal thyroid function—they're at increased risk of developing thyroid problems in the future and should have periodic monitoring. Like thyroglobulin antibodies, elevated TPO antibodies are associated with increased miscarriage risk even with normal thyroid hormone levels. Autoimmune thyroid disease often runs in families and is much more common in women.

Deficiency is uncommon but can cause anaemia that doesn't respond to iron supplements, nerve problems, and weakened immunity. It can occur with excessive zinc supplementation (zinc and copper compete for absorption), malabsorption conditions, and very restrictive diets.

As its name suggests, FSH stimulates the growth and development of ovarian follicles—the fluid-filled sacs in the ovaries that contain eggs. Each month, FSH prompts several follicles to begin developing, and as they grow, they produce oestradiol. Eventually, one follicle becomes dominant and releases a mature egg at ovulation.\u003c\/p\u003e\n \u003cp\u003eBaseline FSH levels (measured on day 2-3 of the menstrual cycle) are one of the most commonly used markers of ovarian reserve—an indication of how many eggs remain in your ovaries and how well they may respond to stimulation. The feedback loop works like this: when ovarian reserve is good and follicles respond readily to FSH, the ovaries produce adequate oestradiol, which signals the pituitary to keep FSH production moderate. When ovarian reserve is diminished and follicles respond less well, the pituitary compensates by producing more FSH—essentially \"stepping on the gas\" to try to stimulate the remaining follicles.\u003c\/p\u003e\n \u003cp\u003eNormal day 2-3 FSH levels are typically between 3-10 IU\/L. Levels above 10 IU\/L may suggest reduced ovarian reserve, and levels above 15-20 IU\/L often indicate significantly diminished reserve. However, FSH must be interpreted alongside oestradiol (a high oestradiol can artificially suppress FSH, masking reduced reserve) and in the context of your age—ovarian reserve naturally declines with age, and a given FSH level means different things at 28 versus 42. Persistently elevated FSH above 25-40 IU\/L, combined with absent periods and low oestradiol, is consistent with menopause or premature ovarian insufficiency. Results outside the normal range may need a follow-up with your GP or a fertility specialist.\u003c\/p\u003e\n \u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003cinput type=\"checkbox\" id=\"meditest-bio-lh-fertf\"\u003e\n \u003cdiv class=\"biomarker-item\"\u003e\n \u003clabel for=\"meditest-bio-lh-fertf\" class=\"biomarker-header\"\u003e\n \u003cspan class=\"biomarker-name\"\u003eLH (Luteinising Hormone)\u003c\/span\u003e\n \u003cspan class=\"dropdown-icon\"\u003e▼\u003c\/span\u003e\n \u003c\/label\u003e\n \u003cdiv class=\"biomarker-content\"\u003e\n \u003cp\u003eLuteinising Hormone (LH) is produced by the pituitary gland and works alongside FSH to regulate the menstrual cycle and ovulation. While FSH stimulates follicle growth in the first half of the cycle, LH triggers ovulation—the release of a mature egg from the dominant follicle. The dramatic surge in LH that occurs mid-cycle (the \"LH surge\") is what home ovulation predictor kits detect. After ovulation, LH also stimulates the empty follicle to transform into the corpus luteum, which produces progesterone to support early pregnancy.\u003c\/p\u003e\n \u003cp\u003eBaseline LH levels (measured on day 2-3) are typically similar to or slightly lower than FSH, usually between 2-10 IU\/L. The ratio of LH to FSH provides additional diagnostic information. In healthy women, the LH:FSH ratio is typically around 1:1 or slightly less. An elevated LH:FSH ratio (often 2:1 or 3:1) is characteristic of polycystic ovary syndrome (PCOS), one of the most common causes of anovulatory infertility. In PCOS, tonically elevated LH disrupts the normal hormonal signalling needed for regular ovulation.\u003c\/p\u003e\n \u003cp\u003eVery low LH levels may indicate a problem with the pituitary gland or hypothalamus (hypothalamic amenorrhoea), which can occur with extreme weight loss, excessive exercise, or severe stress. Like FSH, persistently elevated LH combined with absent periods may indicate menopause or premature ovarian insufficiency. Results should be interpreted alongside FSH, oestradiol, and your clinical picture. Results outside the normal range may need a follow-up with your GP or a fertility specialist.\u003c\/p\u003e\n \u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003cinput type=\"checkbox\" id=\"meditest-bio-oestradiol-fertf\"\u003e\n \u003cdiv class=\"biomarker-item\"\u003e\n \u003clabel for=\"meditest-bio-oestradiol-fertf\" class=\"biomarker-header\"\u003e\n \u003cspan class=\"biomarker-name\"\u003eOestradiol (E2)\u003c\/span\u003e\n \u003cspan class=\"dropdown-icon\"\u003e▼\u003c\/span\u003e\n \u003c\/label\u003e\n \u003cdiv class=\"biomarker-content\"\u003e\n \u003cp\u003eOestradiol (also spelled estradiol, abbreviated E2) is the most potent form of oestrogen and the primary oestrogen produced by the ovaries during reproductive years. It's produced by the granulosa cells of developing ovarian follicles in response to FSH stimulation. Oestradiol levels rise as follicles develop during the first half of the menstrual cycle (follicular phase), peak just before ovulation, drop briefly, then rise again during the second half (luteal phase) before falling to trigger menstruation if pregnancy doesn't occur.\u003c\/p\u003e\n \u003cp\u003eBaseline oestradiol (measured on day 2-3) should be relatively low—typically below 200 pmol\/L (or approximately 55 pg\/mL). If oestradiol is elevated early in the cycle, this may indicate an ovarian cyst, early follicle recruitment, or declining ovarian reserve. Importantly, an elevated baseline oestradiol can artificially suppress FSH levels, making FSH appear normal when ovarian reserve is actually diminished. This is why oestradiol and FSH should always be interpreted together.\u003c\/p\u003e\n \u003cp\u003eVery low oestradiol levels combined with elevated FSH indicate ovarian insufficiency or menopause—the ovaries are no longer producing adequate oestrogen despite high FSH stimulation. Low oestradiol with low FSH and LH suggests a problem at the level of the pituitary or hypothalamus (hypogonadotropic hypogonadism). Normal oestradiol with an elevated LH:FSH ratio may be seen in PCOS. Oestradiol is also important beyond fertility—adequate levels are needed for bone health, cardiovascular protection, and general wellbeing.

Its main function is to stimulate breast milk production after childbirth, but it also plays important roles in reproductive function even outside of pregnancy and breastfeeding. In non-pregnant, non-breastfeeding women, prolactin levels should be relatively low—typically below 500-600 mU\/L (or approximately 25 ng\/mL, depending on the assay).\u003c\/p\u003e\n \u003cp\u003eElevated prolactin (hyperprolactinaemia) is an important and treatable cause of infertility. High prolactin suppresses the release of GnRH (gonadotropin-releasing hormone) from the hypothalamus, which in turn reduces FSH and LH secretion from the pituitary. This disrupts the normal hormonal signals needed for follicle development and ovulation. Women with hyperprolactinaemia may experience irregular periods, absent periods (amenorrhoea), milky nipple discharge (galactorrhoea) even without pregnancy, and difficulty conceiving.\u003c\/p\u003e\n \u003cp\u003eThe most common cause of significantly elevated prolactin is a prolactinoma—a benign (non-cancerous) tumour of the pituitary gland that secretes prolactin. Fortunately, prolactinomas are usually easily treated with medication (dopamine agonists like cabergoline or bromocriptine), which can normalise prolactin levels, restore ovulation, and allow conception. Other causes of elevated prolactin include certain medications (particularly some antipsychotics and anti-nausea drugs), hypothyroidism, and sometimes PCOS. Mildly elevated prolactin can also result from stress, recent nipple stimulation, or blood sampling conditions—this is why morning sampling after rest is important. If prolactin is elevated, repeat testing and further investigation (possibly including pituitary imaging) is usually recommended. Results outside the normal range may need a follow-up with your GP or an endocrinologist.\u003c\/p\u003e\n \u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003c\/div\u003e\n \u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003c\/div\u003e\n \u003c\/div\u003e\n \u003c\/div\u003e\n\n \u003c!-- Section 7: Medical Disclaimer --\u003e\n \u003cdiv class=\"disclaimer-section\"\u003e\n \u003ch3\u003eMedical Disclaimer\u003c\/h3\u003e\n \u003cp\u003eThis test provides important information about hormonal factors that may affect fertility, but it is not a complete fertility assessment.
