Webelevated levels of thyrotrophin (TSH) and elevated TBGlevels, should be similar to the serumT3levels we have observed in patients with overt hypo-thyroidism (figure 4). The explanation for this phenomenon is unknown; however, it does empha-size the dissociation between maternal and fetal thyroid hormone secretion and also suggests that WebTSH assays in DBS samples are typically carried out in a 96-well plate in which the first antibody is bound to the side of the well. Calibrators and quality controls for the assay are prepared from whole blood samples on dried filter paper of …
WebA radioimmunoassay capable of measuring thyrotropin (TSH) in human serum has been developed. Separation of antibody-bound from free 131 I-TSH was accomplished by differential solubility in alcoholsaline. Partial cross-reactions of human TSH with human chorionic gonadotropin (HCG) and human luteinizing hormone (HLH) were demonstrated. Web7 de mar. de 2024 · What is radioimmunoassay?
