Bland-Altman difference plot for canine C-reactive protein measured in canine serum samples with a new species-specific immunoturbidimetric assay (Gentian Canine CRP Immunoassay) in comparison to a validated human based test system (Randox Canine CRP assay). The solid blue line demonstrates the mean % bias, the thin solid grey line is consistent with the identity line. The dashed brown lines show the limits of agreement, which are defined as the mean difference plus and minus 1.96 times the standard deviation (SD). The solid red line indicates the desired total allowable error (TEdes) of 29.6% [32]. A small bias of 5.2% with a confidence interval of 95% (green dotted lines) is present
