What is a Trend arrow in the FreeStyle Libre 14 day reader? How does it work? What does it tell users?

A Glucose Trend Arrow indicates which way your glucose is going and is displayed on the FreeStyle Libre 14 day reader screen after you use the reader to scan your sensor. When there is no Glucose Trend Arrow, the system can't tell if your glucose is rising quickly or falling quickly and will display a check glucose symbol. Whenever you see the check glucose symbol, you should do a blood glucose test and treat based on that result1.
