About Thyroid antibodies

What are thyroid antibodies?

The thyroid gland is a butterfly-shaped gland in the front of the neck that produces hormones responsible for many functions including metabolism, heart function, digestion and mood. Triiodothyronine (T3) and thyroxine (T4) are the two main hormones produced by the thyroid gland. Thyroid peroxidase is the enzyme responsible for converting T4 to T3.

Antibodies are proteins typically produced by the immune system to target and protect against harmful entities. In some cases, the immune system can malfunction, producing autoantibodies which target and attack the body’s own cells.

Thyroid peroxidase antibodies are produced in Hashimoto’s disease and Graves’ disease. Thyroglobulin (a protein specific to the thyroid gland) antibodies may be produced in thyroid cancer or autoimmune conditions.

Why take the test?

This test measures the level of thyroid antibodies against thyroid peroxidase and thyroglobulin to investigate autoimmune thyroid diseases.
