Clinical Significance

Disorders of the thyroid gland are frequently caused by autoimmune mechanisms with the production of autoantibodies. The determination of TPOAb levels is the most sensitive test for detecting autoimmune thyroid disease. The detection of TPOAb is an aid in the diagnosis of thyroid autoimmune disorders and enables the physician to differentiate thyroid autoimmune disorders from non-autoimmune goiter or hypothyroidism.
