Anti Thyroid Peroxidase Antibody; Anti Tpo (Offer)

The Anti Thyroid Peroxidase Antibody (Anti-TPO) (Offer) test is a blood test that measures antibodies against thyroid peroxidase (TPO), an enzyme essential for the production of thyroid hormones. The presence of Anti-TPO antibodies indicates that the immune system is attacking the thyroid gland, making this test one of the most sensitive investigations for detecting autoimmune thyroid disorders. It is particularly useful in diagnosing Hashimoto’s thyroiditis, Graves’ disease, and idiopathic myxedema.

The Anti-TPO test is commonly recommended for individuals with symptoms of thyroid dysfunction, abnormal thyroid function test results, thyroid enlargement (goiter), or suspected autoimmune thyroid disease. It is also valuable in evaluating patients with subclinical hypothyroidism, as the presence of Anti-TPO antibodies increases the risk of progression to overt hypothyroidism. The test helps healthcare providers confirm the diagnosis of autoimmune thyroid disorders, monitor disease progression, and make informed treatment decisions. When interpreted alongside TSH, Free T3, Free T4, and clinical findings, the Anti-TPO test provides a comprehensive assessment of thyroid health and supports timely diagnosis and management.
