Thyroid Peroxidase AB (TPO)
What's Included?

A Thyroid Peroxidase (TPO) Antibody detects antibodies against TPO in the blood. Thyroid peroxidase is an enzyme normally found in the thyroid gland, which plays an important role in the production of thyroid hormones.

The presence of thyroid peroxidase antibodies suggests that the cause of thyroid disease is due to an autoimmune disorder such as Hashimoto's thyroiditis.

The immune system normally makes antibodies to detect and destroy bacteria or viruses. In autoimmune disorders, your immune system makes antibodies that mistakenly attack normal tissue such as thyroid peroxidase. Antibodies that attack the thyroid gland cause inflammation and impaired function of the thyroid.

Thyroid peroxidase antibodies can also be present in other thyroid diseases. Also, some people who have normal thyroid function may have TPO antibodies. However, the presence of thyroid peroxidase antibodies may increase the risk of future thyroid disorders.
