Anti-thyroid Peroxidase Antibody (TPOAb) Test Description
The Anti-thyroid Peroxidase Antibody (TPOAb) test measures the level of antibodies against thyroid peroxidase, an enzyme important for thyroid hormone production. High levels of these antibodies indicate that the immune system is attacking the thyroid gland, which is common in autoimmune thyroid disorders.
Indications of the Test
This test is mainly ordered to diagnose and monitor autoimmune thyroid conditions such as Hashimoto’s thyroiditis and Graves’ disease. It helps explain causes of thyroid dysfunction, thyroid inflammation, or an enlarged thyroid (goiter) when thyroid hormone tests show abnormalities.
Patient Preparation/Instructions
No special fasting is required before the test. However, it is advised not to take biotin supplements for at least 12 hours before blood sample collection, as biotin may interfere with the test results.
Typical Reference Values
The normal range for TPOAb is typically less than 35 IU/mL, but this can vary slightly by laboratory. Elevated levels suggest an autoimmune thyroid disorder, though final interpretation should be done with other thyroid tests.
Time it takes to get Report
Test results are generally available within 6 to 24 hours after sample collection, depending on the laboratory’s processing speed.
