CORRELATION
The analyzer can be set to correlate with or match the results of
another analyzer. To correlate the EasyStat analyzer to a reference
analyzer, data must first be collected from samples run on both ana-
lyzers. The correlation values can be applied to patient and quality
control results.
First, analyze a minimum of 10 patient samples in each of the low
abnormal, normal, and high abnormal ranges for each of the analytes.
Each patient sample must be run on both analyzers. The EasyStat
correlation equations must be set with the default (1.00x + 0.0) coef-
ficients when analyzing the samples.
Next, determine the correlation factors by performing a regression
analysis of the data. The EasyStat data must be the “x” data, and
the reference analyzer must be the “y” data. The regression slope
is entered as the correlation slope, and the regression intercept is
entered as the intercept.
