Bland-Altman difference plot for canine C-reactive protein (CRP) measured in canine serum samples and canine lithium heparin (Li-Hep) samples with a Gentian Canine CRP Immunoassay. The black line is consistent with the zero line. The blue line indicates the mean bias and its 95%-confidence interval (green dotted line). The dotted brown line is consistent with the ±1.96 standard deviation (SD) of the mean absolute bias indicating the limits of agreement. The red line indicates the desired maximum total allowable error (TEdes) of 29.6% [32] for measurement of canine CRP
