They stimulate secretion of T3 and T4 It seems to me like both TSI and TrAb bind to the TSH receptors on thyroid glands which both overproduces T3 and T4 leading to Graves disease.

WebAntibodies with agonist action are also called thyroid stimulating immunoglobulins (TSI). The diagnosis of GD is typically confirmed with TSI titer which is positive in >90% of patients. In patients that have negative TSI, highly sensitive and specific assays for detecting TRAb antibodies are available but they are rarely ordered. WebAug 31, 2024 · Patients. According to a recent study [] showing that the diagnostic sensitivities of TSI and TRAb were 100% and 94.7% for GD, respectively, the number of GD samples needed to identify the superior effect of TSI in diagnosing GD was at least n = 149 (Z-test with α = 0.05, 1-β = 0.9, tests for paired sensitivities in PASS15.0). shops in madison in

Although the sensitivity was 100%, the correlation between the new TSI assays and current TRAb assays was just acceptable, which may be due to the new assays measuring some level of blocking antibodies as well.
