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 are a marker of autoimmune thyroid activity, the test is often used alongside other thyroid function studies to clarify what is driving an abnormal thyroid result.
About TPO Test (Thyroid Peroxidase Antibody) in Maricopa
Thyroid peroxidase antibodies are autoantibodies directed against thyroid peroxidase, an enzyme the thyroid gland uses to attach iodine to thyroglobulin during hormone synthesis.
When the immune system mistakenly identifies thyroid peroxidase as a threat, it can produce antibodies that interfere with normal hormone production and contribute to gradual gland damage. Elevated levels are commonly associated with autoimmune thyroid conditions, including Hashimoto's thyroiditis and Graves' disease.
The TPO test is typically ordered when a person has symptoms or laboratory findings suggesting an underactive or inflamed thyroid, such as fatigue, weight changes, or an elevated thyroid-stimulating hormone level. It helps distinguish autoimmune causes from other explanations for thyroid dysfunction.
Results are interpreted alongside other thyroid tests, including TSH, free T4, and sometimes thyroglobulin antibodies. A positive result does not by itself confirm a diagnosis, and a negative result does not rule out thyroid disease, so the full clinical picture matters.
