The Freestyle Libre sensor is able to store 8 hours worth of glucose data. As long as you scan once every 8 hours all data will be captured. If more than 8 hours passes between scans, there will be a blank space on your graph where data had been erased to store only the most recent 8 hours.
There is no maximum to the amount of time you can scan! We recommend scanning often throughout the day. This includes right away when waking up, before meals, 1 hour after meals, and before bed! The more often you scan, the more real-time knowledge you gain into your glucose levels!
