Thyroglobulin antibodies are one of the main thyroid antibodies measured in a thyroid antibody test.

Why it matters: A positive thyroglobulin antibody result may mean Hashimoto's disease. After thyroid surgery and radioactive iodine therapy for thyroid cancer, the presence of these antibodies, and especially rising levels, may mean the cancer has come back.
