Thyroid
The thyroid produces a hormone that regulates the body’s metabolism and growth. Autoimmune thyroid disorders can cause the thyroid gland to either make too much thyroid hormone (Hyperthyroidism) or too little thyroid hormone (Hypothyroidism). Common tests for diagnosing thyroid disorders are Thyroid-stimulating Immunoglobulin (TSI), Thyroid Antibodies test, and the Iodine Urine Test, 24-Hour. Thank you for browsing our selection of Thyroid blood tests and panels. Shop additional Autoimmune Tests confidentially and order online without insurance or a doctor's note.
