TRAb ELISA kits are assays designed to detect thyroid stimulating hormone receptor antibodies. These are antibodies directed against TSH receptors and can have a stimulating effect (TSAb) or blocking effect (TBAb). Autoimmune production of TRAb plays a large role in the pathogenesis of Grave’s disease, a common form of hyperthyroidism. It can also be used as an indicator of thyroid eye disease.
