Thyroid peroxidase (TPO) is an enzyme primarily found in the thyroid gland, where it plays a crucial role in thyroid hormone production. Anti-TPO antibodies are autoantibodies produced by the immune system that mistakenly target this enzyme. The presence of Anti-TPO antibodies indicates an autoimmune response directed against the thyroid. Measuring Anti-TPO antibodies helps assess for autoimmune thyroid conditions.
