The UK has recently introduced advanced X-ray baggage scanners at airports, designed to speed up the security process and improve the overall travel experience. These new scanners will change the rules around hand luggage, allowing passengers to keep liquids and electronics in their bags during security checks and carry liquids in quantities larger than 100ml. However, the implementation of these scanners is staggered, with many airports expected to fully adopt the new system by June 2024, and some granted extensions until 2025 (ABTA).

For travelers with diabetes who need to carry insulin and diabetes technology, understanding how these scanners affect their medical supplies is crucial.

Understanding the New CT Bagage Scanners

These new scanners use computed tomography (CT) technology to create detailed 3D images of the contents of carry-on luggage. This advanced imaging capability allows security personnel to thoroughly inspect bags without requiring passengers to remove liquids or electronic devices, which can be particularly beneficial for those carrying essential medical supplies.

Key Concerns and Manufacturer Guidance

Insulin and X-ray Scanners:

• Insulin: Insulin can safely pass through these new CT baggage scanners without being affected. The temperature and composition of insulin remain stable after exposure to these scanners, ensuring its effectiveness.

Continuous Glucose Monitors (CGMs)

• FreeStyle Libre: Abbott, the manufacturer of FreeStyle Libre, advises that their CGM sensors are safe to pass through standard X-ray scanners. However, to date, it is unclear whether unopened Freestyle Libre are safe to go through the new CT baggage scanners. Users can request alternative screening methods such as pad down and visual inspection of the bag at security if they prefer​ (Freestyle Libre)​​.

• Dexcom: Dexcom recommends avoiding X-ray and full-body scanners for their CGM systems. They also do not recommend having Dexcom go through the new airport CT baggage scanner.  Instead, they suggest requesting hand-wanding or a pat-down and visual inspection to avoid potential damage to the CGM components​ (Dexcom)​​.

• Omnipod: Insulet, the maker of Omnipod, confirms that their insulin pods are designed to withstand the new airport CT baggage scanners without issues. However, they recommend users to notify security staff about their devices​ (Omnipod)​.

Insulin Pumps:

• General Advice - always consult your healthcare professional and insulin pump manufacturer to be sure: Most manufacturers recommend that insulin pumps should not go through these scanners. Pods from omnipod and infusion sets are fine to pass through the new CT  baggage scanners. Travelers should always inform security personnel about their medical devices to ensure proper handling.

Practical Tips for Travelers with Diabetes

1. Prepare Documentation: Carry a letter from your doctor that explains your medical condition and the necessity of your diabetes supplies.

2. Keep Devices Accessible: Pack your diabetes supplies in an easily accessible part of your carry-on bag to streamline the security process.

3. Communicate: Inform the security personnel that you are carrying diabetes supplies and whether you are wearing any medical devices. Most airport staff are trained to handle such situations with care and understanding.

4. Request Alternative Screening: If you prefer not to have your devices go through the scanner, you can request a manual inspection. This is particularly relevant for devices like insulin pumps and Dexcom.

Conclusion

The introduction of new CT X-ray scanners at UK airports marks a significant advancement in travel security and efficiency. For travelers with diabetes, this technology not only promises a smoother security experience but also ensures that their essential medical supplies can be safely and efficiently screened. By staying informed and prepared, you can navigate these changes with confidence, ensuring that your journey is as stress-free and safe as possible.
