Several studies have been conducted to support the accuracy of the FreeStyle Libre system: The Performance and Usability of a Factory-Calibrated Flash sugar Monitoring System¹ study (2015) evaluated the performance and usability of the FreeStyle Libre flash sugar monitoring system by comparing interstitial sugar results against finger prick sugar results. Both the IMPACT² and the REPLACE³ studies showed that the FreeStyle Libre system could safely and successfully replace routine self-monitoring of blood sugar (SMBG) and delivers important clinical benefits. Both the IMPACT² and the REPLACE³ studies showed that the FreeStyle Libre system could safely and successfully replace routine self-monitoring of blood sugar (SMBG) and delivers important clinical benefits. The REPLACE study produced results that were published online in Diabetes Ther in 2016.
