Getting Through Airport Security with the Dexcom G5® Mobile CGM System

Dexcom G5 Mobile can be a great travel companion; you can go through metal detectors, be hand wanded, and even keep your receiver on during your flight. This section only covers the Dexcom G5® Mobile CGM System. It doesn’t cover steps you need to take when traveling with your smart device. See your smart device’s user guide for travel tips.

Walk-Through Metal Detectors

Transmitter and Sensor


Go through walk-in metal detectors or be handwanded without worrying about damaging your transmiter or sensor. If you’re concerned or uncomfortable about walking through the metal detector, the Transportation Security Administration (TSA) requests you tell the Security Officer you’re wearing a continuous glucose monitor and want a full-body pat-down with a visual inspection of your sensor and transmitter. 


Let the Security Officer know the sensor can’t be removed because it’s inserted under 

the skin.

X-Ray Machines

Receiver, Extra Sensors


Don’t put your Dexcom G5® Mobile CGM System components through baggage x-ray machines. Before your screening process begins, ask the TSA Officer to perform a visual inspection of the receiver and your extra sensors. Place all Dexcom G5® Mobile components in a separate bag before handing over to the Security Officer. For other medical supplies, such as medications, meters, and strips, check manufacturer’s instructions or the TSA website.


Click here to download our "Notice of Medical Device" letter. This can be filled out by your physician and presented to airport security to better explain your Dexcom CGM System.


Use of AIT body scanners has not been studied and therefore we recommend hand-wanding or full body pat down and visual inspection in those situations.

In the Plane

You may keep the receiver on: 


1. Before take-off 


2. While in flight 


3. After landing


The Dexcom G5® Mobile CGM System is safe for use on U.S. commercial airlines. 


If you choose to use your smart device, the airlines request you put your smart devices in airplane mode. You can do this, but still keep your Bluetooth on and you will be able to receive sensor glucose information on your smart device.
