The Freestyle Libre 3 is a revolutionary glucose monitoring system. It allows you to effortlessly check your glucose levels without fingerstick pricks. This guide will walk you through the process of scanning your Libre 3 sensor using your Android smartphone or tablet.

Getting Started: Before You Scan

Before you begin, ensure you have everything you need:

• Freestyle Libre 3 Sensor: Make sure it's properly applied and warmed up (allow at least an hour after application).
• Charged Android Device: Your phone or tablet needs sufficient battery life to complete the scan.
• Freestyle Libre 3 App: Download and install the official Freestyle Libre 3 app from the Google Play Store. Ensure it's up-to-date.
• Bluetooth Enabled: Make sure Bluetooth is turned on in your Android device's settings.

Step-by-Step Scanning Instructions

Here's how to scan your Freestyle Libre 3 sensor:

1. Open the App: Launch the Freestyle Libre 3 app on your Android device.
2. Sensor Activation: If it's your first time using a sensor, follow the on-screen prompts to activate it. This usually involves scanning the sensor's NFC tag.
3. Hold Your Phone Near the Sensor: Hold your Android phone or tablet within a couple of centimeters of the sensor. The sensor's reader area is marked clearly on the sensor itself. You should see a circular graphic on the sensor's surface.
4. Align for Scan: Ensure your device's NFC antenna is positioned correctly over this area. This may require some slight adjustments to find the optimal position for the scan.
5. Scan Completion: The app will vibrate and display your glucose reading once the scan is successful. This usually takes only a few seconds.
6. Review Your Reading: Carefully review your glucose reading, trend arrow, and other available data on the app's display.

Troubleshooting Common Issues

• Unable to Scan: Make sure your device's Bluetooth and NFC are both enabled. Try restarting your device and the app. Check the sensor for any visible damage or debris that might be interfering. Ensure the sensor has been properly warmed up.
• Inconsistent Readings: If you notice inconsistent readings, try recalibrating with a fingerstick glucose meter if your doctor recommends this. Ensure you're scanning the sensor correctly.
• App Errors: Update your app to the latest version. Check your internet connection, as the app may need connectivity for certain features. If the problem persists, contact Abbott Diabetes Care customer support.
