TRAb refers to thyrotropin receptor antibodies. High values of thyrotropin receptor antibodies are indicative of Graves’ disease, autoimmune thyroiditis and other conditions that require prompt medical attention. Thyrotropin receptor antibodies are one of the indicators of thyroid antibodies and have become the first line of diagnosis of Graves’ disease, with a 98% positive rate in patients with untreated Graves’ disease. When the value of thyrotropin receptor antibody is elevated, it is recommended that the patient go to the endocrinology department of a regular hospital for timely consultation and treatment under the guidance of a specialized doctor, so as to avoid delaying the condition.
