About TPO Test (Thyroid Peroxidase Antibody) in Keystone
The TPO antibody test detects and quantifies antibodies directed against thyroid peroxidase, an enzyme involved in the production of thyroid hormones.
Thyroid peroxidase, or TPO, is an enzyme located in the thyroid gland that plays a central role in generating the hormones thyroxine and triiodothyronine. When the immune system mistakenly identifies TPO as a threat, it can produce antibodies against it. These antibodies may interfere with normal thyroid function and are often associated with autoimmune thyroid conditions.
A TPO antibody test is typically ordered alongside other thyroid tests, such as thyroid-stimulating hormone and free thyroxine, to help clarify the underlying cause of abnormal thyroid function. Elevated TPO antibodies are commonly seen in Hashimoto's thyroiditis, an autoimmune condition that can lead to hypothyroidism, and in other forms of autoimmune thyroid disease. Results are interpreted in the context of a person's symptoms, medical history, and other laboratory findings.
Because TPO antibodies can be present in people with normal thyroid function, the test alone does not diagnose a specific condition. It is one piece of a broader clinical picture. Healthcare providers use the result to guide further evaluation and to monitor thyroid status over time. Sample collection involves a routine blood draw, and no special preparation beyond following the laboratory's instructions is generally required.
