What to do with CGM devices during tests

Sensors, transmitters, receivers or insulin pumps should not be exposed to x-rays, CT scans, MRI, any radiation or strong electromagnetic fields.

You must remove the sensor/transmitter attached to your body before the test. You will have to insert a new sensor after the test. You should plan to do this at home if possible as there may not be enough time or space for you to do this in the test area.

Icon Footnote

Remember, all the components of your CGM or monitoring system could be damaged and must not be exposed to x-rays, CT scans, MRI, any radiation and/or strong electromagnetic fields.
