Can Thyroid Peroxidase Antibody Test Diagnose Thyroid Disease?


What is a thyroid peroxidase antibody test? Can this test diagnose thyroid disease?


Thyroid peroxidase (TPO) is an enzyme existing in the thyroid gland. It plays an essential part in the production of thyroid hormones. In a TPO test, antibodies against TPO in the blood can be detected. If a person is diagnosed with thyroid disease, the doctor may recommend him a TPO antibody test along with some other tests to find out what the causes is.

Once the presence of TPO antibodies in your blood is confirmed, the doctor will tell you that the cause of your thyroid problem is an autoimmune disorder. It could be Grave’s disease or Hashimoto’s disease. If you are pregnant with an autoimmune disorder involving the thyroid gland, your doctor will also order the test.

Some people have TPO antibodies, but they are not affected by thyroid disease. Unfortunately, the presence of it may increase their risk of thyroid disorders. They should have periodic medical checkups to prevent thyroid issues.
