Analysis of GlucoMen®Day: A Novel Microdialysis-based Continuous Glucose Monitor

In this issue of Journal of Diabetes Science and Technology, Valgimigli and colleagues present promising data on the clinical accuracy of the new microdialysis-based continuous glucose monitoring device GlucoMen®Day. In this analysis, two issues are addressed: first, the established way data analyses may obscure interindividual variability in terms of a glucose monitoring system’s accuracy; and second, to fully appreciate the future merits of the new system, data on accuracy, while a clearly necessary prerequisite, are not sufficient and need to be augmented by patient-reported outcome data as highlighted by recent U.S. Food and Drug Administration guidelines. J Diabetes Sci Technol 2010;4(5):1193-1194 ORIGINAL ARTICLES Back in the early 2000s, the first papers on the GlucoDay glucose monitoring system developed by A. Menarini Diagnostics were published, and the device hit the European markets soon after. It has taken quite a long time for details of the successor device to be
