Description
Thyroglobulin (Tg) is a protein produced by the thyroid that is used to make the thyroid hormones, T3 and T4. The immune system in some people will manage their own thyroglobulin as a foreign attacker and generate proteins called antibodies that specifically target thyroglobulin. These thyroglobulin antibodies damage the function of thyroglobulin and the whole thyroid gland.
Anti-thyroglobulin antibodies (TgAbs) are mostly associated with Hashimoto`s thyroid disease which is why the thyroglobulin antibody blood test is part of the Hashimoto`s blood test panel. Thyroglobulin antibodies are also at times found in people with hypothyroidism caused by Graves` disease and thyroglobulin antibody testing is sometimes included on with the Graves` disease test panel.
Thyrogloblin antibody lab testing is also occasionally used when screening for recurrent thyroid cancer.
Thyroglobulin Antibodies - Measurement of thyroglobulin antibodies is useful in the diagnosis and management of a variety of thyroid disorders including Hashimoto`s thyroiditis, Graves` disease and certain types of goiter.
This test includes Thyroglobulin Antibody (TAA or TgAb).
