Does the sensor's accuracy remain stable during the 15-day wearing period?
Clinical testing data showed that 99.9% of FreeStyle 2 Plus sensor readings fell within zones A and B of the consistency error grid (a tool used to analyze clinical accuracy). Falling within zones A and B indicates that actions taken by the user based on that reading had little to no negative impact on clinical outcomes2.
The same clinical trial also showed that the FreeStyle Libre 2 Plus sensor meets or even exceeds the stringent US FDA standards for iCGM accuracy10,85.
Furthermore, even if blood sugar levels are low, declining, or changing rapidly, it is not necessary to confirm this through a finger prick10 to make a treatment decision.
