ONE Continuous Glucose Monitoring System

Dexcom inc.

Percutaneous interstitial-fluid glucose monitoring system, electrochemical

No MRI/CT/diathermy – MR unsafe. Do not wear any component of Dexcom ONE during magnetic resonance imaging (MRI), computed tomography (CT) scan, or highfrequency electrical heat (diathermy) treatment.

Dexcom ONE has not been tested in those situations. The magnetic fields and heat could damage the components of Dexcom ONE, which may cause it to display inaccurate CGM sensor glucose readings (Dexcom ONE readings) or may prevent alerts. Without Dexcom ONE readings or alert notifications, you might miss a severe low or high glucose event.
