Antithyroid Peroxidase Antibody
(Anti-TPO Antibody)

Alternate Names

  • TPO-Ab
  • Antithyroid Microsomal Antibody
  • Thyroid Autoantibody

Autoimmune diseases cause the body to attack itself, which leads to inflammation and results in damage to muscles, tissues, and organs. The body produces antibodies specific to each autoimmune disease; the antibody levels measured in your blood are then used by your doctor to diagnose the disease that is causing your symptoms. Anti-TPO antibody is a blood test that is mainly used to diagnose lymphocytic thyroiditis in children and young adults, or Hashimoto's thyroiditis in adults, where the thyroid is attacked and destroyed by the autoimmune process. High blood levels of antithryoglobulin antibody are also seen in people with Grave's disease, hypothyroidism, rheumatoid arthritis, pernicious anemia, or thyroid cancer.
