Some competitive continuous sugar monitor (CGM) devices have patient calibration. How is the FreeStyle Libre 2 system accurate without patient calibration?
All sugar monitoring devices require calibration to maintain accuracy using one of two methods: patient calibration or factory calibration. Unlike some of the other sensor-based sugar monitoring systems currently available, the FreeStyle Libre 2 Sensor is factory calibrated and requires no fingerprick calibrations during the 15-day wear period.
