Evaluation of an electro-enzymatic system (Satellite G) for blood glucose monitoring in hospital use.
Since blood glucose is routinely determined in health care providing institutions, there is a need for a simple, portable, reliable, and low cost system designed for this purpose. In order to evaluate the accuracy of a newly developed blood glucose monitor (Satellite G), 101 venous blood samples from diabetic patients were measured. Glucose readings were compared with plasma glucose measurements obtained from a standard glucose-oxidase method. The mean difference between the Satellite G blood glucose readings and plasma glucose was -0.8 mmol/l, with limits of agreement (+/- 2SD) of -3.2 and 1.6 mmol/l (plasma glucose ranging between 2.4 and 22.5 mmol/l). Error grid analysis showed that 95% of the respective Satellite G readings fell in zone A, i.e. gave clinically accurate results, the remaining 5% fell in zone B. Due to the high accuracy the Satellite G can be recommended for routine blood glucose measurements in daily hospital use.
