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
