Thyroid Peroxidase Test Index

Featured: Thyroid Peroxidase Test Main Article

The thyroid peroxidase test measures the level of an antibody that is directed against thyroid peroxidase (TPO). A presence of TPOAb in the blood reflects a prior attack by the body's immune system on thyroid tissue. A positive thyroid peroxidase test may signal chronic thyroiditis. Other autoimmune disorders, however, may have a positive TPOAb test.
