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.

Do users have to remove the Sensor during MRI/CT scan?

If the user has a medical appointment that includes strong magnetic or electromagnetic radiation, for example an X-ray, MRI (Magnetic Resonance Imaging), or CT (Computed Tomography) scan, they need to remove the Sensor they are wearing and apply a new Sensor after the appointment. The effect of these types of procedures on the performance of the system has not been evaluated.1
