Evaluation of the Accuracy and Precision of Flash Glucose Monitoring Sensors in Different Sites

Three FGM sensors will be inserted simultaneously (one on the back of the upper arm, abdomen and thigh) and will be worn for a consecutive 14 days. Throughout the study, patients should measure capillary blood glucose (BG) with the built-in BG meter of the Freestyle Libre at least 7 times per day (before and 1-2 hours after every meal and before bedtime). Additionally, patients should scan each sensor at least every 8 hours to obtain every measured interstitial glucose value. At the end visit (after 14 days), patients will come back to the hospital to download FGM and SMBG data.
