After The Test & Treatment Options
After the Test
Once your specimen is submitted, results are typically processed and available within a few business days. However, processing times may vary. When ready, your results will be delivered in a clear, easy-to-understand report. If any results suggest a potential infection, you’ll receive a call from an independent healthcare coordinator. Independent physicians are also available to answer any questions or discuss your results in detail.

Test Details & What It Measures
A TPO (Thyroid Peroxidase) Antibody test measures the presence of antibodies against thyroid peroxidase, an enzyme that plays a key role in the production of thyroid hormones. The presence of these antibodies is an indication that the immune system is mistakenly attacking the thyroid gland, a condition known as autoimmune thyroid disease. This test is often used to help diagnose conditions like Hashimoto’s thyroiditis (an autoimmune form of hypothyroidism) or Graves’ disease (an autoimmune disorder causing hyperthyroidism).
Normally, the levels of TPO antibodies in the blood are very low or undetectable. Elevated levels of TPO antibodies can suggest that the body is attacking its thyroid, potentially leading to thyroid dysfunction. A positive result may indicate an autoimmune thyroid disorder, even before symptoms appear. It is important to note that people can have elevated TPO antibodies without showing signs of thyroid disease, though they may be at a higher risk of developing thyroid problems over time.
