About the Libre 3

The Libre 3 is the smallest all-in-one sensor that contains both the sensor and transmitter in a single unit. 

  • Sensor Life: The Libre 3 sensors last for 14 days each. You will receive two 14-day sensors per shipment in your Levels kit, providing you with 28 days of glucose tracking.
  • Data Transmission: The Libre 3 sensor calculates a glucose value every minute, glucose values are stored every 5 minutes, and the glucose data is then transmitted via Bluetooth to your mobile device in real time. You'll need to keep the Libre 3 app on and open and within 33 feet of your sensor to receive data. 
  • Sensor Data Storage: The Libre 3 can store up to 14 days of your most recent glucose data when the Bluetooth signal is weak or disrupted. 
  • Calibration: The Libre 3 is factory calibrated and does not require manual calibration. The Libre 3 does not have the ability to manually calibrate the sensor.
  • Warm up period: The sensor will take 60 minutes to warm up after application before it will begin reading glucose data.
  • Size: The Libre 3 sensor is round in shape .1" in height and .8" in diameter.
