Thyroid Peroxidase Antibody (TPO)

This test measures Thyroid Peroxidase (TPO) antibodies, which are found in most people with autoimmune hypothyroidism. TPO is an enzyme within the thyroid gland that is essential for producing the hormones your body needs for health. Understanding your TPO antibody level is a key step in evaluating your thyroid health. Although the test is not used alone for diagnosis, high levels may indicate an increased likelihood of developing an autoimmune thyroid disorder. Knowing this vital information helps guide proactive health management.
