Accuracy evaluation of two portable blood glucose meters in feline patients using whole blood samples

ABSTRACT: Using portable blood glucose meters (PBGMs) to measure (BG) concentration is a common procedure in veterinary practice. Our objective was evaluate the analytical and clinical accuracy of human PBGM (Accu-Chek Performa®), (AC) (GlucoCalea®), (GC) feline patients. Central venous samples were collected from 48 cats at Brazilian Veterinary teaching hospital. Two devices each model used compared reference method (RM). Analytical assessed according ISO 15197:2013 requirements for PBGMs. Data using Wilcoxon’s nonparametric test represented by Bland-Altman plots. Hematocrit’s effect on BG measurements evaluated Spearman correlation coefficient. Clinical determined error grid analysis (EGA). Values significantly higher all PBGMs RM. Although ISO’s could not be met any devices, AC more accurate than GC meters. All - but ones within zones A B EGA, meeting accuracy. Significant hematocrit interference observed devices. Therefore, showed greater whole samples.
