Evaluation of Two Methods of Self Blood Glucose Monitoring by Trained Insulin-dependent Diabetic Adolescents Outside the Hospital

Abstract

We studied the accuracy of the Chemstrip bG and Glucometer systems in the self-monitoring of blood glucose by trained adolescents. The determinations were done at home with simultaneous collection of whole blood into capillary tubes (Sarstedt) which were later analyzed by a glucose-Oxidase analyzer (Beckman Instruments). In both cases, there was an excellent correlation between laboratory concen-trations and Chemstrip bG (r = 0.96, P < 0.001) and Glucometer (r = 0.96, P < 0.001). Comparisonsmade at 8 mo remained with the same degree of accuracy. There was a trend toward greater deviation with higher plasma glucose values. Well-trained patients can achieve sufficientaccuracy to permit the use of either of the methods tested with similar results.
