Why doesn’t the FreeStyle Libre system need calibrating?

Unlike other sensor-based glucose monitoring systems that are currently available, the FreeStyle Libre Sensor is factory calibrated and requires no fingerprick calibrations during the 14-day wear period. FreeStyle Libre system is a factory calibrated Sensor that has been proven to safely and successfully replace SMBG and deliver important clinical benefit. Specific details about our calibration process are proprietary.
