The absolute difference between POCgluc and LABgluc increased as the PCV changed from 50%. As PCV decreased, POCgluc was falsely increased as PCV increased, POCgluc was falsely decreased, compared with LABgluc. Results-Values of LABgluc for each sample were similar at any PCV. Measurements of POCgluc, PCV, and LABgluc were also determined from blood samples of 30 dogs admitted to the veterinary teaching hospital. A correction formula for POCgluc was developed. Duplicate POCgluc and PCV measurements were obtained for each dilution following POCgluc measurements, plasma samples were analyzed for glucose concentration by a clinical laboratory biochemical analyzer (LABgluc).

Packed RBCs were resuspended with plasma to achieve a range of PCVs from 0% to 94%. Samples were processed into packed RBCs and plasma. Procedures-60 mL of heparinized blood was obtained from each of 6 healthy dogs. Samples-Blood samples from 6 healthy dogs and from 30 hospitalized dogs. Objective-To determine the effect of PCV on veterinary point-of-care (POC) glucometer measurements in canine blood samples and develop a formula to correct the glucose concentration as measured by a point-of-care glucometer (POCgluc) given a known PCV.ĭesign-Experimental and prospective study. The 5 interpretation zones for consensus error grid analysis are as follows: A = no effect on clinical action B = altered clinical action unlikely to affect outcome C = altered clinical action likely to affect clinical outcome D = altered clinical action could have serious medical risks and E = altered clinical action could have dangerous consequences. The 5 risk levels for Clarke error grid analysis are as follows: A = 20% but leads to no treatment or benign treatment C = overcorrection of acceptable blood glucose concentration or misinterpretation of euglycemia for hyper- or hypoglycemia D = dangerous failure to detect and treat because of estimated blood glucose concentration errors and E = erroneous treatment (ie, treatment contradictory to that actually required). Results of Clarke error grid analysis (panels A and B) and consensus error grid analysis (panels C and D) of the experimental (black circles 6 healthy dogs) and validation (open squares 30 dogs admitted to the veterinary teaching hospital) data are shown.
