Quick answer
The TPO antibody test measures autoantibodies that target thyroid peroxidase, an enzyme the thyroid uses to make hormones. Their presence points to an autoimmune process affecting the thyroid. The test is usually ordered with other thyroid tests and is interpreted by a qualified healthcare provider.
What this test measures
Thyroid peroxidase is an enzyme in the thyroid gland that plays a key role in producing thyroid hormones. In autoimmune thyroid disease, the immune system produces antibodies against this enzyme and other thyroid proteins. Detecting these antibodies can support the evaluation of conditions such as Hashimoto thyroiditis and other forms of thyroid inflammation.
The test needs a blood sample, drawn from a vein. The laboratory measures thyroid peroxidase antibodies with an immunoassay and reports a level against a reference range. Because these antibodies can appear alongside thyroglobulin antibodies, TPO testing is often combined with other thyroid markers such as TSH and free T4.
A positive result indicates autoimmune activity against the thyroid, but it does not by itself confirm a specific diagnosis or predict how symptoms will progress. Some people with antibodies have normal thyroid function. A qualified healthcare provider interprets the result with hormone levels and clinical findings.
