A thyroglobulin antibody test checks for antibodies that target thyroglobulin, a protein made by the thyroid gland. It is ordered to help evaluate autoimmune thyroid conditions and to interpret thyroglobulin levels in people treated for thyroid cancer.

What it measures

  • Thyroglobulin Antibodies — The amount of these autoantibodies in the blood.
  • Thyroglobulin — Often measured alongside; antibodies can interfere with this test.

  • Free Thyroxine (Free T4) — A thyroid hormone that helps assess gland activity.

Who it is for

A healthcare provider may order this test if you have symptoms of a thyroid disorder, abnormal thyroid test results, or are being monitored for thyroid cancer.

Preparation
