Hyperthyroidism is short for hyperthyroidism. The indicators of hyperthyroidism include thyroid stimulating hormone (TSH), serum total thyroxine (TT₄), serum total triiodothyronine (TT₃), serum free thyroid hormone, thyroid stimulating hormone receptor antibody (TRAb), and thyroid stimulating antibody (TSAb). Changes in serum TSH concentration are the most sensitive indicator of thyroid function.TT₄ indicator is stable and reproducible, and is one of the main indicators for the diagnosis of hyperthyroidism. Serum free thyroid hormones include free thyroxine (FT₄), free triiodothyronine (FT₃). Free thyroid hormone is the major part of realizing the biological effects of this hormone. TRAb has become the first line of diagnosis for Graves’ disease, with a 98% positivity rate in patients with untreated Graves’ disease.TSAb, in contrast to TRAb, reflects the fact that this antibody not only binds to the thyrotropin receptor but also produces a stimulatory function on thyroid cells. It is recommended that patients with hyperthyroidism consult an endocrinologist for treatment under the supervision of a physician.
