Thyroid Function with Antibodies Blood Test Kit

£63.00

Biomarkers (0)

Including thyroid hormones, thyroid peroxidase antibodies, and thyroglobulin antibodies to assess thyroid function and autoimmunity.
    Description

    The Thyroid Function with Antibodies Blood Test measures key thyroid hormones and checks for thyroid antibodies to assess thyroid performance and identify potential autoimmune thyroid conditions.

    Key Features

    • Measures essential thyroid hormones, including TSH, FT4, and FT3.
    • Detects thyroid antibodies that may indicate autoimmune conditions such as Hashimoto’s thyroiditis or Graves’ disease.
    • Provides a comprehensive view of thyroid health and function.
    • Laboratory-tested for accuracy and reliability.

    Product Information

    This test combines standard thyroid function analysis with antibody testing, offering a deeper understanding of thyroid performance and immune system involvement. It can help in identifying both overactive and underactive thyroid conditions, as well as immune-related thyroid issues.

    Note

    Testing should be arranged through a qualified healthcare provider. Results must be interpreted by a medical professional to ensure accurate diagnosis and appropriate follow-up care.

    What's in the test?

    • Autoimmunity

      Thyroglobulin antibodies

      This test looks for antibodies to thyroglobulin, a protein which is specific to the thyroid gland. Under normal circumstances it does not enter the bloodstream, but if your thyroid is inflamed or under attack from the body's own immune system, then thyroglobulin can be secreted and antibodies detected. Most cases of thyroid disease are caused by an autoimmune condition where the thyroid gland is attacked by the body's own immune system. This can cause the thyroid gland to produce more thyroid hormone (as in the case of Graves' disease) or to produce less as the cells in the thyroid gland are gradually destroyed (as in the case of Hashimoto's thyroiditis).

      Thyroid peroxidase antibodies

      Thyroid peroxidase (TPO) is an enzyme important in the production of thyroid hormones. This test looks for antibodies against TPO which are often raised in cases of autoimmune thyroid conditions and occasionally in healthy individuals.

    • Thyroid hormones

      TSH

      Thyroid stimulating hormone (TSH) is produced in the pituitary gland in order to regulate the production of thyroid hormones thyroxine (T4) and triiodothyronine (T3) by the thyroid gland. If thyroid hormones in the blood are low, then more TSH is produced to stimulate the thyroid gland to produce more of them. If thyroid hormone levels are high, then the pituitary produces less TSH to slow the production of thyroid hormones. If TSH is too high or too low, it normally signifies that there is a problem with the thyroid gland which is causing it to under or over produce thyroid hormones. Sometimes a disorder of the pituitary gland can also cause abnormal TSH levels.

      Free T3

      Triiodothyronine (T3) is the more active of the two thyroid hormones produced by the thyroid gland. Most T3 is bound to protein in the blood. Free T3 measures the level of T3 that is free, or unbound to protein, and is available to regulate metabolism.

      Free thyroxine

      Thyroxine (T4) is one of two hormones produced by the thyroid gland. It works to speed up the rate of your metabolism. Most T4 is bound to carrier proteins in the blood - it is only the free, or unbound, T4 that is active in the body, which is measured in this test. Free T4 is the less active of the two main thyroid hormones. To have an impact on your cells it needs to convert to the more active T3 when your body needs it.
