Freestyle Libre

  • Continuous Glucose Monitoring (CGM):
    • The FreeStyle Libre is a CGM system designed to help people with diabetes monitor their glucose levels continuously throughout the day and night. It provides real-time information about glucose trends.
  • Sensor Technology:
    • The system consists of a small, disposable sensor that is inserted just beneath the skin. The sensor measures glucose levels in the interstitial fluid, providing a representation of blood glucose levels.
  • Flash Glucose Monitoring:
    • Unlike traditional glucose monitoring systems that require fingerstick blood samples, the FreeStyle Libre uses flash glucose monitoring. Users can obtain glucose readings by scanning the sensor with a reader or a compatible smartphone.
  • Reader or Smartphone App:
    • The FreeStyle Libre system includes a handheld reader or a mobile app that works with compatible smartphones. Scanning the sensor with the reader or app provides information about current glucose levels, trends, and historical data.
  • No Calibration Required:
    • Unlike some other CGM systems, the FreeStyle Libre does not require routine fingerstick calibration. However, users may still need to calibrate the system occasionally for accuracy.
  • Data Storage and Trends:
    • The system stores glucose data, allowing users and healthcare providers to review patterns, trends, and time in range over specific periods.
  • Water-Resistant:
    • The sensor is designed to be water-resistant, allowing users to wear it while showering or swimming within certain limitations.
  • 14-Day Wear:
    • Each sensor is designed for wear for up to 14 days, after which it needs to be replaced with a new sensor.
  • Alarm Settings:
    • Users can set up alarms to receive notifications if glucose levels are above or below specified thresholds.
  • Ease of Use:
    • The FreeStyle Libre system is known for its ease of use, eliminating the need for frequent fingersticks and providing a more continuous and convenient way to monitor glucose levels.
