For diabetes patients, keeping glucose levels balanced is vital yet challenging. Continuous glucose monitoring through skin sensors like the FreeStyle Libre provides convenient, real-time data to better control fluctuations.
The FreeStyle Libre system uses a small, wearable sensor to measure interstitial fluid glucose without finger sticks. This offers complete insight into trends so you can understand impacts from food, exercise and medication.
Here's an in-depth look at the components, accuracy, cost and what existing users have to say about the much-buzzed Libre sensor.
Overview of Freestyle Libre Continuous Glucose Monitoring
The FreeStyle Libre was among the first CGM systems to eliminate routine finger pricks. Key features include:
14-day disposable sensor worn on back of arm
Water resistant design for showers and exercise
Real-time glucose readings when scanned by reader
Historical data, trends and patterns viewable on reader
Optional smartphone app integration
The sensor uses wired enzyme technology to measure glucose in interstitial fluid through a tiny filament inserted under skin. The reader communicates with sensor to capture this data.
Step-by-Step Guide on Using The Libre CGM System
Setting up the Libre kit is straightforward:
Charge reader before first use
Download/connect app if using (optional)
Apply single-use sensor on upper arm using applicator tool
Activate sensor by scanning it with reader
Begin scanning sensor at any time to check glucose
Sensor can be worn both day and night for 14 days
Remove and replace sensor afterwards
After the initial 1-hour warmup, you start building comprehensive glucose profile effortlessly through quick, occasional scans using the reader anytime, anywhere.
