The Freestyle Libre sensors store 8 hours of glucose readings. If the sensor is not scanned within 8 hours from the last scan, it will not be able to hold more the most current 8 hours of data. This may result in a gap in the line of your glucose graph and inaccuracies for scores calculated around those times of missing data.

How often should I be scanning my sensor? Looks like it’s doing it automatically all day
