- A1, A2: CVs for intra-assay imprecision of two canine serum pools analyzed 20 times in a single run without recalibration.
- A – D: Inter- and intra-assay CVs of 6 canine serum pools analyzed in duplicates twice daily over 5 days.
- CVs not fulfilling the quality specifications i.e., are higher than 12.2% [32] are marked in bold letters.Abbreviations: n.d. = not done, SDÂ =Â standard deviation; CVÂ =Â coefficient of variation.
