Inter- and intra-assay reliability of DecisionDx-UM. a Inter-assay correlation of discriminant scores for 16 samples run on 3 consecutive days. b Bland-Altman plot showing the difference in discriminant scores between runs and the 95% confidence interval (dashed lines). The estimated bias (or mean difference in discriminant values) is represented as the red line. c Inter-assay correlation of discriminant scores of 46 samples run twice during a one-year period for proficiency testing or instrument verification. d Bland-Altman plot of proficiency testing and instrument verification samples. e Intra-assay correlation of discriminant scores of 12 samples tested in duplicate on two cards. f Bland-Altman plot showing differences in paired discriminant scores within each card
