Thyrotropin receptor antibodies generally refer to thyrotropin hormone receptor antibodies. Whether TRAb34IU/L requires treatment should be judged in conjunction with thyroid function. If the patient has a disease such as Graves’ disease, once diagnosed, treatment is usually required. Thyrotropin Receptor Antibody (TR-Ab), the upper limits of TR-Ab are 1.22IU/L and 1.58IU/L for healthy individuals and non-Graves’ disease patients with thyroid disorders, respectively, and are considered to be on the higher side when they are 34IU/L. Further thyroid function tests, such as thyrotropin, free thyroid hormone, total thyroid hormone, etc., are usually needed to determine the diagnosis of Graves’ disease, and if Graves’ disease is diagnosed, antithyroid medications, such as methimazole, propylthiouracil, etc., are needed to treat the disease. In addition, elevated TR-Ab can also be seen in autoimmune thyroiditis. However, only elevated TR-Ab without thyroid function abnormality and no obvious clinical symptoms can be observed temporarily without treatment. In the case of elevated TR-Ab, it is recommended to go to the hospital and ask the doctor to determine whether medication is needed.
