    • Abstract:
      We compared measurements of blood glucose concentrations in 30 healthy adult White New Zealand rabbits using 2 commercial portable glucometers (PGM1 and PGM2) and a laboratory chemical analyzer. Results were analyzed with Pearson correlation, Passing–Bablok regression analysis, Bland–Altman analysis, and a modified error grid. Measurements with PGM1 were significantly correlated (r = 0.37) with those obtained from the laboratory reference method (RM); Bland–Altman and Passing–Bablok analyses indicated no significant systematic or proportional differences (mean difference of −0.26, 95% CI of mean difference of −0.54 to 0.01, and LOA of −1.70 to 1.17); and error grid resulted in 100% of measurements in zone A. No significant correlation (r = −0.05) was detected between PGM2 and RM; Bland–Altman and Passing–Bablok analyses results indicated a mean difference of 2.14, 95% CI of mean difference of 1.67–2.60, and limit of agreement of −0.32 to 4.59, which overestimated blood glucose concentration, with 53% of glucose measurements in error grid zone A and 47% in zone B. PGM1 was considered accurate in normoglycemic rabbits, whereas the use of PGM2 could result in overestimations of glycemia. [ABSTRACT FROM AUTHOR]
