The FreeStyle Libre sensor collects glucose data every minute and automatically stores a reading every 15 minutes. When scanned with the reader or FreeStyle LibreLink app, it provides the user with:
• Current sensor glucose reading,
• A graph of stored glucose readings.
• It also typically displays a glucose Trend Arrow pointing to where glucose levels are heading.1
Depending on the direction of change, you can use the Trend Arrow alongside your current glucose reading to make an informed decision as to whether to take any corrective action.
