Abstract
Introduction: Frequent and accurate blood glucose measurements and control can delay the onset of diabetic complications. This is facilitated by the use of point-of-care glucose meters (POCGM). There is a need to verify some claims made by manufacturers of POCGM with regard to accuracy, precision and linearity. To verify some of these claims, we compared blood glucose results obtained from Accu-Check Instant blood glucose meters with laboratory results as a reference.
Method: This cross-sectional analytical study involved verifying some characteristics of AccuChek Instant POCGM using different concentrations of glucose calibrators prepared in-house. Blood was obtained from volunteers who did not need an overnight fast. It was tested using Accu-Chek Instant POCGM and routine laboratory glucose oxidase method as a reference and compared using the Bland-Altman plot. Statistical significance was set at p<0.05.
Results: There were 188 blood samples tested using the two methods. The difference between the means of glucose values from the two methods was 10.3 mg/dL (12.8%), with Accu-Chek POCGM returning higher results than the routine laboratory method. The difference was not statistically significant using the Bland-Altman plot (p=0.60). The analytical range of the POCGM was determined to be between 20mg/dl to 300 mg/dL. Results indicating ‘Hi’ on the POCGM were below 600 mg/dL, contrary to what was claimed by the manufacturer.
Conclusions and Implications: There was some agreement between the two methods studied. Results obtained at high glycaemic states may be more precise but are lower than central laboratory values.

Key words: Diabetes mellitus type 2, Blood glucose self-monitoring, Fasting blood glucose, Reproducibility of results, Humans
