Reports on biological variation of plasma biochemical indicators are limited. We evaluated biological variations of 13 plasma biochemical indicators.Plasma samples were collected from 40 healthy individuals over 5days. Intra-individual coefficient of variation (CVI), inter-individual coefficient of variation (CVG), index of individuality (II), reference change value (RCV), and analytical goal parameters...
Biological variation is used in the calculation of reference change values (RCVs) for a delta check. In this study, we examined the correlation between intra-individual biological coefficients of variation (CVI) and delta check limits according to population distribution.A total of 1,533,359 paired test results of nine routine chemistry tests were used to make the population distributions of delta...
