Abstract
The performance of six self-monitoring blood glucose (SMBG) machines (Accutrend ®, Reflolux S ®, Companion 2 ®, Glucometer GX ®, Glucometer IV ® and One Touch II ®) were examined using venous blood samples from 88 patients. Whole blood glucose (BG) values were measured by four machines from each brand. Machine-generated whole blood glucose (BG) values were corrected before comparison with laboratory plasma glucose values, measured by a glucose oxidase method. Based on error grid analysis, most of the corrected machine-generated BG values were clinically acceptable. Accutrend ®, Glucometer IV ® and Companion 2 ® showed the greatest consistency between machines of the same brand. Over 80% of corrected BG values generated by Glucometer IV ® fell within ± 10% of the reference values. One Touch II ® yielded the most reproducible results with a mean CV of 2.7% and was considered the most user friendly machine. More studies are required to examine the performance of these machines in the hands of patients.
