How to Apply the Freestyle Libre 3 Sensor

Applying your Freestyle Libre 3 Sensor is quick and easy. Simply choose a clean, dry area on the back of your upper arm, use the applicator to insert the sensor, and press it firmly into place. Once applied, the sensor begins reading your glucose levels automatically — no finger-sticks needed. Be sure to follow the step-by-step instructions provided in the video or user guide for the best results. The entire process takes just a few minutes and offers up to 14 days of continuous glucose monitoring.

Removing and Replacing Your Freestyle Libre 3 Sensor

Removing and replacing your Freestyle Libre 3 Sensor is simple. Gently peel off the old sensor and dispose of it properly. Clean and dry the application site before applying a new sensor using the applicator. Follow the included instructions carefully to ensure accurate readings and continued comfort. Regular sensor changes help maintain optimal performance and reliable glucose monitoring. If you experience any irritation or issues, contact your healthcare provider promptly.

Getting Started with the App and Sensor

Begin by downloading the companion app on your smartphone. Once installed, open the app and follow the prompts to create your account and pair it with your Freestyle Libre 3 sensor. After applying the sensor, use the app to start monitoring your glucose levels in real time. The app provides easy-to-read data, alerts, and helpful insights to support your diabetes management journey. Regularly updating the app ensures you have access to the latest features and improvements.

Understanding Glucose and Sensor Level Readings

Understand the difference between your actual blood glucose levels and the sensor’s interstitial fluid measurements. While sensor readings provide continuous, real-time data, slight variations can occur compared to traditional finger-stick tests. This comparison helps you make informed decisions about your diabetes management with confidence. Always consult your healthcare provider if you notice significant differences or have concerns about your readings.
