The thyroid antibody test is a diagnostic tool used to assess thyroid function and detect autoimmune thyroid disorders. By measuring the presence of specific antibodies in the blood, such as thyroid peroxidase antibodies (TPO) and thyroglobulin antibodies (TG), this test helps identify conditions like Hashimoto's thyroiditis and Graves' disease. Understand your thyroid health and get an accurate diagnosis with the thyroid antibody test, guiding appropriate treatment and management options.
