This test is aslo known as Thyroglobulin antibody; Thyroiditis - thyroglobulin antibody; Hypothyroidism - thyroglobulin antibody; Thyroiditis - thyroglobulin antibody; Graves disease - thyroglobulin antibody; Underactive thyroid - thyroglobulin antibody; ATG, Anti TG, Anti Thyroglobulin Antibody.
Your thyroid is a gland located in your neck. It releases hormones that control your metabolism. It produces a number of different proteins, including thyroglobulin. Your thyroid uses thyroglobulin to make the active thyroid hormones.
If you have an autoimmune condition, it can disrupt your production of thyroglobulin. An autoimmune condition happens when your immune system creates antibodies that attack your body’s own healthy cells. When your immune system attacks the thyroid, it often targets thyroglobulin. This causes it to produce antithyroglobulin antibodies. Your doctor can order an antithyroglobulin antibody test to check the level of these antibodies in your bloodstream. A high level may indicate an autoimmune condition
Antithyroglobulin antibodies test aids in detecting the possible thyroid problems.
Antithyroglobulin antibodies can be a sign of thyroid gland damage caused by the immune system. They may be measured if thyroiditis is suspected.
Measuring the levels of thyroglobulin antibody after treatment for thyroid cancer can help your healthcare provider to determine what is the best test to monitor for a recurrence of the cancer.
