What is a Thyroid Peroxidase Ab?

An antithyroid microsomal antibody test is also called a thyroid peroxidase antibody test. It measures antithyroid microsomal antibodies in your blood. Your body produces these antibodies when cells in your thyroid become damaged. Your thyroid is a gland in your neck that makes hormones. These hormones help regulate your metabolism. Your doctor may order this test along with other tests to help diagnose thyroid problems or other autoimmune conditions.
