“…Both PBGMs tended towards greater difference from the hexokinase reaction method as blood glucose concentration increased, which is consistent with previous studies (Cohen et al 2009, Johnson et al 2009, Brito-Casillas et al 2014, Kang et al 2016, Mori et al 2016, Mori et al 2017. Almost all blood glucose concentrations obtained by both PBGMs were higher than corresponding blood glucose concentrations obtained by the hexokinase reaction method.…”

“…PBGMs are inexpensive, compact and require only a small volume of blood for glucose measurement, which adds to their appeal in veterinary applications. Device analytical accuracy, as defined by the ability of a glucose monitoring system to produce measurement results that agree with blood glucose concentrations obtained by a reference method (International Standards Organisation 2013, Klonoff 2014) is a variable among PBGMs and only a small number of brands have been calibrated for veterinary patients (Cohen et al 2009, Johnson et al 2009, Paul et al 2011, Kang et al 2016, Mori et al 2017.…”

“…There are numerous studies evaluating the accuracy of humancalibrated portable glucometres when used in animals (Cohn et al 2000, Wess & Reusch 2000, Cohen et al 2009, Johnson et al 2009, Brito-Casillas et al 2014, Kang et al 2016, Mori et al 2016), but whilst the number of brands of commercially available veterinary-calibrated PBGM is increasing, a paucity of information exists with regards to their accuracy (Cohen et al 2009, Johnson et al 2009, Paul et al 2011, Kang et al 2016, Mori et al 2017, Guevara et al 2019. The accuracy of one of the most well-known veterinary PBGM, the AlphaTrak, has previously been investigated (Cohen et al 2009, Paul et al 2011, Kang et al 2016), but to date, no studies have investigated the accuracy of the AccuTell PBGM.…”

Materials and MethOds: One hundred twenty venous blood samples were obtained for immediate whole blood glucose concentration measurement using two portable blood glucose metres designed for use in dogs.Plasma glucose concentration was measured by a laboratory analyser using a hexokinase reaction method.Packed cell volume was measured for each sample. Linear regression analysis was performed and Bland-Altman plots constructed with International Standards Organisation 15197:2013 standards applied to assess relationship and agreement between results of portable blood glucose metres and laboratory analyser methods, respectively. Clarke's error grid analysis was used to assess clinical accuracy and usefulness.results: The AccuTell and the AlphaTrak2 had mean differences of −0.69 ± 0.70 mmol/L (bias ±sd) and −1.09 ± 1.22 mmol/L (bias ± sd) with the reference analyser, respectively. Eighty-eight of 120 (73.3%) samples for the AccuTell, and 73 of 120 (60.8%) samples for the AlphaTrak2 were plotted in the zone of the error grid analysis that indicated less clinical risk of misdiagnosis of glucose status. Neither device fulfilled the International Standards Organisation 15197:2013 standards for system accuracy. A statistically significant effect of packed cell volume was identified on the difference between blood glucose concentration obtained by the AlphaTrak2 and the hexokinase reaction method, but not for the AccuTell.

OBJECTIVE To compare glucose concentrations in peripheral venous and capillary blood samples collected from dogs before and after consumption of a meal and measured with a veterinary-specific portable blood glucose meter (PBGM). ANIMALS 12 dogs (96 blood samples). PROCEDURES A veterinary-specific PBGM was used to measure blood glucose concentrations. Glucose concentrations in capillary blood samples obtained from the carpal pad, medial aspect of a pinna, and oral mucosa were compared with glucose concentrations in blood samples obtained from a lateral saphenous vein. Samples were collected after food was withheld for 12 hours and again 2 hours after consumption of a meal. RESULTS Location of capillary blood collection had a significant effect on glucose concentrations measured with the PBGM. Glucose concentration in capillary blood collected from the medial aspect of the pinna did not differ significantly from the glucose concentration in peripheral venous blood samples, whereas glucose concentrations in blood samples collected from the carpal pad and oral mucosa differed significantly from the glucose concentration in peripheral venous blood samples. There was no significant difference between preprandial and postprandial blood glucose concentrations. CONCLUSIONS AND CLINICAL RELEVANCE Glucose concentrations in capillary blood collected from the medial aspect of the pinna of dogs better reflected glucose concentrations in venous blood than concentrations measured in capillary blood collected from the carpal pad or oral mucosa.
