How Do I Use Freestyle Libre 3? A Step-by-Step Guide For Continuous Monitoring

So, you've got your hands on the Freestyle Libre 3 and you're ready to dive into continuous glucose monitoring. Let's walk through the steps to get you started and make the most of this cutting-edge technology.

Step 1: Preparing the Sensor

• Clean the Skin: Start with clean, dry skin on the back of your upper arm. Avoid using lotions or creams that could interfere with sensor adhesion.
• Apply the Sensor: Peel off the sensor's adhesive backing and gently apply it to the prepared skin area. Press down firmly to ensure good adhesion.

Step 2: Activating the Sensor

• Wait for Activation: After applying the sensor, wait for the activation period (usually one hour) before scanning.
• Scan with Reader or App: Use the Freestyle LibreLink app on your smartphone or the Freestyle Libre 3 reader to scan the sensor. Hold the reader or phone close to the sensor to initiate scanning.
• Calibration (if required): Unlike some continuous glucose monitoring systems, the Freestyle Libre 3 is factory-calibrated and typically does not require manual calibration. Follow any specific instructions provided by your healthcare provider or the device manufacturer.

Step 3: Monitoring and Data Insights

• Continuous Monitoring: Once activated and scanned, the Freestyle Libre 3 starts continuous glucose monitoring. You can check your glucose levels anytime by scanning the sensor with the reader or app.
• Track Trends: Use the data provided by the Freestyle Libre 3 to track glucose trends, patterns, and variability over time. This information can help you make informed decisions about medication adjustments, diet modifications, and lifestyle changes.

Step 4: Managing Alarms and Settings

• Set Alarms (optional): Customize high and low glucose alarms using the Freestyle LibreLink app or reader. This feature can alert you to potential glucose fluctuations and help you take prompt action.
• Adjust Settings: Explore and adjust settings such as glucose units (mmol/L or mg/dL), display brightness, and alarm preferences to suit your preferences and needs.

Step 5: Replacing the Sensor

• Wear Time: The Freestyle Libre 3 sensor is designed for wear for up to 14 days. Replace the sensor promptly after the wear period ends to maintain accurate monitoring.
• Sensor Removal: Gently remove the sensor by peeling it off the skin. Dispose of the used sensor properly according to local guidelines.

Tips for Optimal Use

• Avoid Compression: Minimize pressure or compression on the sensor site to prevent inaccurate readings. Avoid sleeping directly on the sensor or wearing tight clothing that could press against it.
• Stay Connected: Keep your Freestyle LibreLink app updated and ensure your reader is charged for uninterrupted monitoring.
• Skin Sensitivity: Monitor your skin for any signs of irritation or allergies at the sensor site. If you experience discomfort, consult with your healthcare provider.
