Thyroid Antibody Panel
This panel contains the following tests:
- Thyroid antithyroglobulin antibody (ATA)
- Thyroid peroxidase antibody (TPO)
Thyroglobulin and thyroid peroxidase are proteins involved in the production of thyroid hormones. It is possible for antibodies from own immune system to attack these proteins rendering them dysfunctional. Both are often used in conjunction with each other to assess thyroid function, follow treatment for thyroid disease and differentiate between autoimmune conditions of the thyroid. Fasting is not required for this test. Take all medications as prescribed.
