Tpo Antibodies (anti-thyroid Peroxidase Antibodies

The Anti-Thyroid Peroxidase Antibodies (Anti-TPO) test measures the levels of antibodies against thyroid peroxidase (TPO), an enzyme found in the thyroid gland. The presence of these antibodies is often associated with autoimmune thyroid conditions.

The test helps to diagnose autoimmune thyroid diseases such as:

• Hashimoto's thyroiditis: An underactive thyroid (hypothyroidism).
• Graves' disease: An overactive thyroid (hyperthyroidism).

Other thyroid autoimmune disorders

Anti-thyroid peroxidase (TPO) antibodies are primarily measured to help diagnose autoimmune thyroid disorders, such as Hashimoto's thyroiditis or Graves' disease. The test can be recommended for individuals in the following situations:

1. Symptoms of Hypothyroidism
2. Symptoms of Hyperthyroidism
3. Family History of Thyroid Disease
4. Screening for Autoimmune Thyroid Disease

If your health care provider has diagnosed you with hypothyroidism or hyperthyroidism, thyroid antibody tests can help find out if a thyroid autoimmune disease is causing the problem. There are different tests that check for different types of thyroid antibodies. Your provider will choose tests for you based on your symptoms, the results of other tests, and information about your medical history and family health history.
