Abstract

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

两种便携式猫患者全血血糖仪的准确性评价

摘要:在兽医实践中，使用便携式血糖仪(PBGMs)测量血糖(BG)浓度是一种常见的程序。我们的目的是评估人PBGM (Accu-Chek Performa®)(AC)和兽药PBGM (GlucoCalea®)(GC)在猫患者中的分析和临床准确性。在巴西兽医教学医院采集了48只猫的中心静脉血样本。每个模型使用两个装置，并与参考方法(RM)进行比较。分析精度根据ISO 15197:2013对人pbgm的要求进行评估。数据比较采用Wilcoxon非参数检验，并用Bland-Altman图表示。通过Spearman相关系数评估红细胞压积对BG测量的影响。采用误差网格分析(EGA)确定临床准确性。与对照组相比，所有PBGMs的BG值均显著升高。虽然任何设备都不能满足ISO的分析精度要求，但交流仪表比气相色谱仪表更准确。除气相色谱外，所有交流测量值均在EGA的A区和B区范围内，符合ISO对临床准确性的要求。在所有装置中均观察到明显的红细胞压积干扰。因此，与使用猫全血样本的GC相比，AC具有更高的准确性。
