Do not ignore symptoms that may be due to low or high blood glucose. If you have symptoms that do not match the Sensor glucose reading or suspect that your reading may be inaccurate, check the reading by conducting a finger stick test using a blood glucose meter. If you are experiencing symptoms that are not consistent with your glucose readings, consult your health care professional.

How many alarms does the FreeStyle Libre 2 system have?

The FreeStyle Libre 2 system has three real time optional alarms – no scanning required: 

  • Low Glucose Alarm - an alarm will notify you when your glucose falls below a level you set
  • High Glucose Alarm - an alarm will notify you when your glucose rises above a level you set
  • Signal Loss alarm - an alarm will notify you when the glucose alarms you set are not available because your sensor has lost communication with the app for 20 minutes
