Comparison of first-generation and second-generation blood glucose meters for use in a hospital setting.


This study evaluated and compared a first- and a second-generation blood glucose meter for precision, accuracy, and user preference. Two separate capillary blood glucose fingersticks were performed on 25 outpatients and 60 inpatients with diabetes. Samples were drawn for serum glucose determinations immediately following the capillary fingersticks. Comparison of the Accu-Chek II and Satellite G meters in the outpatient setting gave results similar to the reference laboratory's. When the meters were tested on inpatients, the blood glucose results were significantly higher than those obtained from the hospital laboratory. The Accu-Chek II was more precise than the Satellite G on both normal and high blood glucose samples. Nursing staff indicated preference for the Satellite G because of its quick testing time but not for other preference factors surveyed. Both meters provided more accurate assessments of blood glucose concentration than were obtained from the serum glucose samples routinely processed by our hospital laboratory. Use of a nonfluorinated tube and delayed separation of the sample with resultant glycolysis likely account for this difference.
