Thyrotropin Receptor Antibody (TR-Ab) should refer to thyrotropin receptor antibody, greater than 30IU/L usually belongs to the high range, suggesting the possible existence of autoimmune hyperthyroidism, after standardized treatment is generally not serious, if the non-standardized treatment may induce hyperthyroidism crisis and other situations are more serious. Thyrotropin receptor antibody is an antibody that acts directly on the TSH receptor on the membrane of thyroid cells, and the upper limit of TR-Ab is 1.22IU/L and 1.58IU/L in healthy individuals and patients with non-Graves’ disease thyroid disorders, respectively. Therefore, thyrotropin receptor antibody greater than 30IU/L usually indicates high. Measurement of thyrotropin receptor antibodies can be used for the diagnosis or exclusion of autoimmune hyperthyroidism and for the differential diagnosis of multiple nodules with functionally autonomous thyroid gland. Detection of treatment and relapse in patients with Graves’ disease is an important guide to clinical treatment and monitoring. When hyperthyroidism is present, thyroid hormone levels can usually be maintained within a reasonable range after standardized treatment, and the prognosis is good and generally not considered serious; however, if hyperthyroidism is not treated in a standardized manner, it may induce hyperthyroid crisis, which is more serious in this type of situation. It is recommended to go to the hospital if thyrotropin receptor antibodies are greater than 30 IU/L.
