What makes the FreeStyle Libre system different and how?

The FreeStyle Libre system is clinically proven to be accurate, stable and consistent for up to 14 days without the need for fingerstick calibration.

  • The FreeStyle Libre Sensor is factory calibrated and manufactured with minimal Sensor-to-Sensor variation eliminating the need for fingerstick calibration. 
  • To achieve stable performance, the FreeStyle Libre Sensor uses Wired Enzyme technology that is not dependent on oxygen to produce glucose readings and   
  • Allows the Sensor to operate at a very low electrical potential of 40mV vs a silver/silver chloride reference electrode. 1
