Thyroid antibody tests detect antibodies that attack the thyroid gland, which is the hallmark of autoimmune thyroid diseases. This includes TPO antibodies (associated with Hashimoto's thyroiditis) and thyroglobulin antibodies. These tests are important for anyone with abnormal thyroid levels, a family history of thyroid disease, or symptoms of thyroid dysfunction.
Measures TPO antibodies + Thyroglobulin antibodies to diagnose autoimmune thyroid disease (Hashimoto's, Graves'). Confirms etiology when TSH is abnormal.
Anyone with abnormal TSH or Free T4, family history of autoimmune thyroid disease, unexplained miscarriage, postpartum thyroiditis suspicion, or other autoimmune conditions.
