Can CGM Go Through Airport Security? Tips

Will airport security mess with my CGM?” If you had that thought while trying to plan your next trip, you aren’t alone. There is so much to consider when traveling with diabetes – managing your health, traveling through new routines, and the various things that can screw up your plans.

Airport security is one of the most intimidating hurdles for users of Continuous Glucose Monitoring (CGM); thus, it is completely sensible you would ponder how you can get through security without damaging your device or unnecessarily delaying your travel.

First, the good news: travelling with a CGM does not have to be such a challenging task. With a little preparation and understanding of airport processes, you can spend little time navigating checkpoints while continuing to manage your glucose readings confidently. This guide will walk you through all you need to know to fly with a monitor, from TSA details to what to do to travel more efficiently and with less anxiety.

Can CGM Devices Go Through Airport Security?

Of course you can take a CGM through an airport security checkpoint. However, knowing how to convey and follow the screening protocol can help smooth the process and make for a more relaxing screening experience.

Medical Device Status

Continuous Glucose Monitors are classified as medical devices, but you can bring them as carry-on and check luggage. Unfortunately, some CGMs may include electronic components and transmit data wirelessly via Bluetooth or radio frequency; therefore, you may need to endure additional scrutiny. 

TSA’s Official Stance

The TSA officially allows passengers to wear medical devices, including CGMs, through screening, but the TSA advises passengers to let the TSA officer know, so it can be processed correctly through screening procedures. Stating it is a medical device can limit scanners exposure or manual disruption.

How Are CGMs Screened at Airport Security?

Different screening technologies are utilized at security checkpoints, such as millimeter wave scanners, metal detectors, and X-rays, which may have a slightly different effect on CGMS. Therefore, it is helpful to know what to expect.

1. X-ray Machines

These are used to scan carry-on and checked baggage.The majority of transmitters, receivers, and sensors in most continuous glucose monitors (CGMs) can withstand exposure to X-rays. However, it is best to avoid multiple X-ray exposures, particularly for sensors.

Tip: You may want to keep your CGM components in your carry-on baggage so that they are easy to access and don’t suffer abuse in checked baggage.

2. Walk-Through Metal Detectors

Because CGM parts are composed of small amounts of metal, your CGM may trigger metal detectors. 

What to do: Tell the TSA agent that you have a CGM, and then request alternative screening (e.g., manual pat-down or hand-held wand) since you do not want to go through the metal detector again.

3. Millimeter Wave Scanners (Body Scanners)

Millimetre-wave body scanners are safe for CGMs as they produce harmless radio waves. They are now commonly used as the main methods for screening body-related items at most U.S. and international airports.

What to do: These scanners usually do not affect CGMS; however, you should always notify security so that they can proceed according to CGM safety guidelines.

Tips for Traveling with a CGM Through Airport Security

By planning ahead, traveling with your CGM can be stress-free. The following are some tips from travelers who have experience with CGMs: 

1. Carry Documentation

To be safe, carry a prescription or note from your doctor stating that you require a CGM for medical purposes. This can be a lifesaver if you are challenged at screening. 

2. Inform TSA Officers Proactively

When you arrive at the security checkpoint, tell the TSA officer you are wearing a CGM. This will signal the officers to use federal screening procedures for medical devices. 

3. Request Alternative Screening

If the device alarms or you have an alert with certain kinds of scanners, ask for a manual check instead of screening with those devices. 

4. Keep Devices in Carry-On Bags

Do not check anything of any CGM equipment. In your hand luggage, keep your sensors, transmitters, receivers, and backup equipment. 

5. Bring Extra Supplies

You may have delays, lost luggage, or if something just goes wrong as technology sometimes does. In any case, take extra sensors, batteries, patches, and chargers to use as replacements if you need to swap one out. 

6. Know Your Device’s Guidelines

Ensure you are abiding by the travel suggestions for your CGM model. Some brands are clearer than others that you should not expose your CGM to various kinds of scanning equipment, even if the TSA says it is ok. 

7. Use Protective Cases

Keep your CGM parts in a sturdy, cushioned case to prevent unintentional damage.

CGM Use During Flights: Additional Considerations

Here’s how to make sure your CGM will work properly during your travel once you’ve cleared security: 

Altitude and Pressure Changes

CGM’s are designed to operate under standard flight altitude and standard cabin pressure. You can be confident that the device will operate throughout your flight. 

Device Storage

You will want to keep your receiver or connected phone close to your body (in a pocket or in the seatback storage). You will not want to store it in the overhead compartment and miss a reading. 

Insulin and Other Supplies

If you are carrying insulin or other medication, you will want to verify your airline’s position on flying with your diabetes supplies. Normally, with appropriate documentation, you can take insulin when it is in a liquid form. 

What to Do If Your CGM Device Is Flagged at Security?

You have planned well, and now your CGM is flagged. Generally, when your CGM is stopped for additional screening here is how to treat this challenge like a pro: 

• Remain calm and polite. TSA agents are trained for these situations.
• You should inform the TSA agent of your medical documents, including the description of how the CGM operates.
• Ask for a private screening if you would rather not be in a public place.

Preparation to Travel with CGM Devices Through Airport Security

Traveling with a medical device such as a CGM can seem difficult, but if you remember the following 7 steps, you’ll be ok.

• Proactively alert the security agents.
• Bring a note/prescription from your doctor.
• Ask for alternative screening if that will help.
• Pack your carry-on with all of your gadgets and accessories.
• Bring backup supplies.
• If traveling internationally, make sure you look up the country’s security procedures.
• Air travel can challenge your health – be vigilant while flying.

A little preparation can go a long way in making sure that your trip is safe and fun.

Frequently Asked Questions (FAQs)

1. Can I wear my CGM sensor through airport security scanners?

Yes, most CGM sensors are approved to be worn through security. If you are not sure, just ask for alternative screening so you avoid damaging your sensor.

2. Will my CGM device set off the metal detector?

Maybe just tell the agents you have a CGM on your body and ask for a wand or manual if you want.

3. Are CGM devices safe from damage during X-ray screening?

Yes, typically X-rays are fine. However, it is recommended to minimize “x-ray” of the sensors; thus, checking with the manufacturer is always a good idea.

4. What documentation do I need to carry when traveling with a CGM?

A prescription or note from your physician might aid in screening and verify the device’s medical necessity.

5. Can I use my CGM during the flight?

Yes. CGMs work on flights. Just follow the airline rules for Bluetooth and airplane mode.
