There were three replicates for each CSF sample. Nine CSF samples were processed and analyzed together. Data were presented as mean ± standard deviation (coefficient of variation). Coefficient of variation was the ratio of standard deviation to mean presented as percentage and was used to represent within-run imprecision. ^{a} ( under assumption of equal variance versus values of F_{2}-IsoPs for L-CSF processed by the NP method). ^{b} ( under assumption of unequal variance versus values of F_{2}-IsoPs for H-CSF processed by the NP method). ^{c}The difference between the mean values of two methods divided by the mean values from IsoP method is calculated and represented as % of difference.
