Evaluation of one portable blood glucose meter and one portable glucose-ketones meter in dogs

Numerous portable blood glucose meters (PBGMs) have been developed during the last decade, the majority of which is designed for use in humans. Recently one glucometer (Gluco Calea, WellionVet; GC) and one glucose‐ketones meter (Belua, WellionVet; BE) have been developed for use in veterinary medicine. The aims of this study were to assess the accuracy and precision of these devices in feline venous and capillary blood samples based on ISO 15197:2013 and to evaluate packed cell volume (PCV) interferences. Samples were obtained from 29 non anemic cats (PCV 30–47%) and 18 anemic cats (PCV140 mg/dL), medium (90–139 mg/dL), and low ( 0.89). However neither PBGMs totally fulfilled ISO requirements, but 100% of glucose values measured on venous blood using BE fell in zone A+B of EG. Within‐run and between‐day precision were adequate. The effect of PCV was significant (higher results with lower PCV) only for BE. The correlations between capillary and venous 3‐HB and reference 3‐HB were r = 0.66 and r = 0.82 respectively. Mean differences between capillary and venous 3‐HB and reference method were −0.07 (±1.15) and −0.30 (±1.48) respectively; within‐run precision was adequate. Our results show that GC is not sufficiently accurate while the superior performances of BE supports its clinical use in cats.
