Limit of quantification (LoQ) determined in three canine serum pools diluted to low C-reactive protein (CRP) concentrations. Samples were analyzed 36 times on 3 different days with a new automated canine-specific immunoturbidimetric CRP method. The total error (TE) was calculated (TE = bias + 2 standard deviations [SD]). LoQ was 6.8 mg/L, as TE exceeded the set quality goal (29.6%) for lower concentrations.
Expected CRP Concentration (mg/L) | Mean Observed CRP Concentration (mg/L) | SD (mg/L) | TE (%) | TE < TEa |
---|---|---|---|---|
6.8 | 7.1 | 0.39 | 16 | Yes |
4.9 | 5.9 | 0.35 | 38 | No |
2.9 | 4.8 | 0.39 | 90 | No |
TEa indicates allowable total error.
