Why do I need to scan to obtain my glucose level once the system alarms?

The FreeStyle Libre 2 alarms will present to let the user know that their glucose has crossed the set level for a low or high glucose alarm, but the system will not provide a glucose reading. To confirm your glucose level, you will need to scan the FreeStyle Libre 2 Plus sensor.
