The Anti-Thyroid Antibodies Panel (Anti-TG & Anti-TPO) is a blood test used to detect antibodies that target the thyroid gland, which can indicate an autoimmune thyroid disorder. The panel typically measures:
Anti-TPO (Anti-Thyroid Peroxidase) Antibodies: These antibodies attack the thyroid peroxidase enzyme, which is essential for thyroid hormone production. High levels are often found in autoimmune thyroid diseases like Hashimoto's thyroiditis and Graves' disease.
Anti-TG (Anti-Thyroglobulin) Antibodies: These antibodies target thyroglobulin, a protein involved in thyroid hormone production. Elevated levels can also point to autoimmune thyroid diseases, especially Hashimoto's thyroiditis.
