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 marker for thyroid dysfunction. High TSH indicates hypothyroidism (underactive thyroid)—symptoms include fatigue, weight gain, cold intolerance, constipation, low mood, and menstrual irregularities. Low TSH indicates hyperthyroidism (overactive thyroid)—symptoms include anxiety, weight loss, tremor, heat intolerance, and light or absent periods. Thyroid problems are much more common in women than men, and thyroid conditions can significantly affect fertility and menstrual regularity. Hypothyroidism can cause heavy, prolonged periods; hyperthyroidism can cause light or absent periods.

Most T3 is produced by conversion from T4 in your tissues rather than directly by the thyroid. Free T3 measures the unbound, active portion. Some people have difficulty converting T4 to T3, which can cause persistent hypothyroid symptoms despite normal TSH and T4. Low T3 can also occur during illness (sick euthyroid syndrome), with extreme calorie restriction, or with high stress. Free T3 helps complete the picture of thyroid function, particularly when symptoms persist despite treatment or when TSH and T4 don't fully explain symptoms.

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. Testing for thyroid antibodies helps identify autoimmune causes of thyroid dysfunction and can flag increased pregnancy risk.
