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 long can the Sensor be worn?

The disposable Sensor is designed to adhere to the back of the upper arm and provide accurate glucose readings for up to 14 days.  After the 14 days, the user removes the Sensor by peeling off the adhesive pad.1
