In this issue of Journal of Diabetes Science and Technology, Christiansen and colleagues report results from two studies, laboratory and clinical, that assessed the accuracy of a new blood glucose monitoring system, the Contour®Next ONE (Ascensia Diabetes Care, Parsippany, NJ, USA). The new system comprises a blood glucose meter that can link (via Bluetooth®) to the Contour™ Diabetes app, which operates on a smartphone or tablet. Results from both studies showed that the system exceeded the accuracy standards defined by the International Organization for Standardization (ISO) 15197:2013. It is worrisome, however, that many FDA-cleared (and marketed) blood glucose monitoring systems do not meet ISO accuracy criteria. Significant improvements in regulatory oversight and enforcement are needed.
