Anti-Thyroxine Peroxidase
The Anti-Thyroxine Peroxidase (Anti-TPO) Test measures the level of antibodies against thyroid peroxidase, an enzyme crucial for the production of thyroid hormones. This test is primarily used to diagnose autoimmune thyroid conditions, such as Hashimoto's thyroiditis and Graves' disease, where the immune system erroneously attacks the thyroid gland. Elevated levels of anti-TPO antibodies can indicate thyroid inflammation or dysfunction. The test involves taking a blood sample, which is then analyzed in a laboratory to detect and quantify these antibodies.
Monitoring anti-TPO levels is important for guiding diagnosis and treatment for autoimmune thyroid disorders, with testing recommended as needed based on symptoms or clinical diagnosis.
