Table 3.
Repeatability (intra‐assay variability) of three serum samples from dogs analyzed on four different analyzers performed 10 times in one run. None of the variabilities was less than 10%, which is a general target value for repeatability, and only three of the 12 variabilities were within the "poor but acceptable" range of 10%‐20%
