Order TPO Test (Thyroid Peroxidase Antibody)The TPO test measures thyroid peroxidase antibodies, proteins produced by the immune system that target an enzyme involved in thyroid hormone production. Because these antibodies can be present before symptoms appear, the test is often used to clarify the underlying cause of thyroid dysfunction rather than to diagnose it on its own.
About TPO Test (Thyroid Peroxidase Antibody) in Pullman
Thyroid peroxidase antibodies are a marker of autoimmune activity directed at the thyroid gland.
Thyroid peroxidase is an enzyme normally found in the thyroid, where it helps attach iodine to thyroid hormone precursors. In some people, the immune system mistakenly recognizes this enzyme as foreign and creates antibodies against it. The TPO test detects and, in some cases, quantifies those antibodies in a blood sample.
Elevated TPO antibodies are commonly associated with autoimmune thyroid conditions, including Hashimoto's thyroiditis and Graves' disease. They can also appear in individuals with no obvious thyroid symptoms, which is why results are interpreted alongside thyroid function tests such as TSH, free T4, and free T3, as well as clinical history.
The test itself requires a standard blood draw, and results are typically reported as either negative or positive, or as a numeric titer with a reference range. Because antibody levels can fluctuate and do not always correlate directly with symptom severity, the TPO test is best understood as one piece of a broader thyroid evaluation.
