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.

What happens to the Sensor after the 14-day wear period?

After 14 days of wear, the reader notifies the user that the Sensor has ended. The Sensor automatically stops collecting glucose data and should be removed 14 days after being started.1 Time to Sensor end is shown on the Home and Results screens.  Three days before the Sensor ends, it tells users with the first scan of each day.  In the final 8 hours, it tells users with each scan. The Sensor should be replaced with a new Sensor.1
