From: Clinical and analytical comparison of six Simoa assays for plasma P-tau isoforms P-tau181, P-tau217, and P-tau231

Fig. 1

Precision plots of the six P-tau assays. For each assay, concentrations were plotted against the variation in their duplicate measurements (%CV), color-coded for clinical group. Due to technical reasons, duplicate results were obtained for 66/80 samples with P-tau181 Eli Lilly, for 74/80 with P-tau181 ADx, for 79/80 with P-tau217 Eli Lilly, for 79/80 with P-tau231 ADx, and for 77/80 with P-tau231 Gothenburg. Horizontal dashed lines were set at CV 20%, vertical dashed lines were set at the functional LLOQ for each assay (i.e., analytical LLOQ multiplied by sample dilution factor). CV coefficient of variation; P-tau phosphorylated tau, LLOQ lower limit of quantification
