If you have diabetes and use a Continuous Glucose Monitor (CGM), medical tests or treatments may harm your CGM.
If you are going for any of the tests or treatments below, you should take your CGM off.
Take off your CGM sensor when you are at home, before you leave for your test or treatment. You may not have enough time or room to do this at the hospital.
If you are having radiation treatment:
If you forget that your sensor is on during your treatment or test, take it off as soon as you notice. Medical tests and treatments can harm the sensor. You may not be able to rely on your CGM readings. Do not reuse that sensor again.
When you are not using your CGM, you can use finger-prick testing.
For questions about your blood sugars or testing call your Diabetes Education Team, Endocrinologist (diabetes doctor) or family doctor.
If you have questions about your CGM device or sensor, contact the Product Support Team for your device. The contact number can be found on the device website or app.
