THYROGLOBULIN ANTIBODIES

THYROGLOBULIN ANTIBODIES

Thyroglobulin (Tg) is a protein produced uniquely by your thyroid gland. This test measures the amount of thyroglobulin in the blood.

The thyroid gland produces hormones (thyroxine or T4 and triiodothyronine or T3) that help to regulate the rate at which the body uses energy. It is a small, butterfly-shaped organ that lies flat against the windpipe at the base of the throat and is composed primarily of very small, ball-shaped structures called follicles that produce and store thyroglobulin.

Antithyroglobulin antibodies can be a sign of thyroid gland damage caused by the immune system. They may be measured if thyroiditis is suspected.

A thyroglobulin antibodies (TgAb) test is used to check blood levels of antibodies the body has made against the compound thyroglobulin.
