Thyroid peroxidase autoantibodies (TPOAb) are of pathological importance because they are present in the majority of Hashimoto’s thyroiditis patients and correlate with the active phase of the disease. Unlike thyroglobulin autoantibodies (TgAb), they may damage thyroid cells by complement fixation. The detection of thyroid peroxidase autoantibodies (TPOAb) and thyroglobulin autoantibodies (TgAb), and the measurement of thyroid stimulating hormone, have been used in determining the diagnosis and management of autoimmune thyroid disorders.
