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.

Can a user still scan and get the last 8 hours of data after the Sensor has ended after 14 days?

The user is provided with one last opportunity to scan the Sensor after the 14 days have ended.  The reader will acquire any data still remaining on the Sensor that was obtained prior to the end of the 14-day wear period.1
