High thyrotropin receptor antibodies are indicative of autoimmune thyroid disorders such as Graves’ disease. Thyrotropin Receptor Antibody (TRAb) is a thyroid antibody test, which is very important for diagnosing Graves’ disease and can also assist in diagnosing the cause of hyperthyroidism; TRAb is not detected in the blood of normal people, so elevated levels of TRAb suggest the presence of an autoimmune thyroid disorder. In Graves’ disease, thyrotropin receptor antibodies can be positive in more than 95% of patients. In addition, thyrotropin receptor antibodies can be positive in diseases such as subtle thyroiditis and autoimmune thyroiditis. It is recommended that patients with high thyroid receptor antibodies should go to the hospital to have the cause of the disease identified and treated under the guidance of the doctor.
