Does a low glucose alarm show as red in the 8-hour history?
Alarm events will not appear in the FreeStyle Libre 2 Reader logbook. If a user gets an alarm and then scans, the scan result would be stored in the logbook. Alarm events do not change the 8-hour history presentation. If the user gets an alarm and scans the Sensor and their glucose has been below 70 mg/dL for over 15 minutes, the 8-hour history will show red.
