How often should I scan the sensor?

You can scan your sensor as often as you'd like — there is no limit!

If you’re using the LibreLink app:

Scan your sensor at least once every 8 hours to transfer data from the sensor to your phone and to get a full picture of your glucose levels.

If you have an external reader:

You don’t need to scan your sensor as often because all data is stored in the sensor itself. But we recommend you make the most of your time with the sensor by scanning it 2-3 hours after eating to learn more about your blood sugar responses.
