Anti-thyroglobulin antibody

Antithyroglobulin antibody is a test to measure antibodies to a protein called thyroglobulin. This protein is found in thyroid cells.

This test helps detect 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 thyroglobulin antibody levels after treatment for thyroid cancer can help your provider decide what the best test is to monitor you for a recurrence of the cancer.
