How To Get Started With the Libre 3 Continuous Glucose Monitor
Read the Official Instructions First
Always read the complete Instructions for Use included inside your product carton.
Prepare the Sensor and Application Area
The Libre 3 sensor is placed on the back of the upper arm for the best results. Applying it elsewhere can lead to inaccurate readings. Ensure the chosen area avoids scars, moles, stretch marks, tattoos, or recent insulin injection sites. Wash the area thoroughly and clean the site with an alcohol wipe. This allows the skin to air-dry completely.
Apply the Sensor Correctly
The Libre 3 comes in a pre-assembled, one-piece applicator unit, eliminating the manual assembly. Apply the sensor correctly by following the instructions.
Pair or Start the Sensor With the Compatible Device
Open the Libre 3 app on your compatible smartphone. Hold your smartphone near the sensor and once recognized, the app connects to the sensor via Bluetooth for continuous streaming. Keep your device within Bluetooth range during regular wear.
Wait for the Sensor to Become Ready
After successful pairing, the sensor enters a mandatory 60-minute warm-up period.
Set Up Alerts Carefully
The Libre 3 system features optional alerts. Always have your diabetes care team specify your personal low and high targets.
