iChemVELOCITY Urinalysis System
Method Comparison
The performance of the iChemVELOCITY was compared with
commercially available urinalysis systems. Urine samples were from a
hospital or a commercial laboratory. Samples with concentrations
covering the entire assay reporting range were tested. The urinalysis
systems used provided semi-quantitative and/or qualitative results with
the exception of SG, where quantitative results were provided. The exact
% agreement and % agreement within +/- one report level is shown for all
tests. SG comparison was done by linear regression (n= 248, R2 =
0.999, slope = 1.013, intercept = -0.014).
