Assessment of Glucose Concentrations in People Without Diabetes Mellitus After Standardized Meals and in Daily Life

Assessment of Glucose Concentrations in People Without Diabetes Mellitus After Standardized Meals and in Daily Life

Participants will perform blood glucose monitoring (BGM) over the course of 14 days and, in parallel, wear continuous glucose monitoring (CGM) systems. Because current CGM systems typically achieve a lower level of analytical accuracy than BGM systems, participants will perform at least 5 blood glucose (BG) measurements per day. In addition, CGM systems are used to obtain minimally-invasive high-frequency glucose measurements to fill the gaps between BG measurements.
