Reply to Drs. Kiaei and Molinaro Regarding the Publication “Comparison of a Bridge Immunoassay with Two Bioassays for Thyrotropin Receptor Antibody D…
2020
Dear Editor,Drs. Kiaei and Molinaro 1 put forth two criticisms of the manuscript published by us 2. They state that the experimental design of this study is flawed and that the authors falsely claim that negative Thyretain™ TSI Reporter BioAssay results for two Graves’ diseases patients undergoing drug treatments means the absence of stimulating antibodies. To substantiate this claim Drs. Kiaei and Molinaro point out that the manufacturer of the Thyretain TSI Reporter BioAssay clearly states in the package insert that “[t]he effects of various drug therapies on the performance of this Kit have not been established” 1. Second, the package insert explicitly states that “[a] negative result do…
Comparison of a Bridge Immunoassay with Two Bioassays for Thyrotropin Receptor Antibody Detection and Differentiation
2019
AbstractA rapid and fully automated chemiluminescent immunoassay for the detection of thyrotropin receptor autoantibodies (TSHR-Ab) based on a bridge technology was compared with two bioassays that measure either stimulating (TSAb) or blocking (TBAb) antibodies for the detection and differentiation of TSHR-Ab. A total of 229 patients with various thyroid disorders [151 with Graves’ disease (GD), 35 with Hashimoto’s thyroiditis (HT), 32 with nodular goiter, and 11 with thyroid cancer] were included. The bridge immunoassay was performed according to the manufacturer’s instructions (cut-off>0.55 IU/l). TSAb and TBAb were measured with reporter bioassays. Blocking activity was defined as per…
