What You'll Learn
Libre 2 sensors can go through metal detectors
The Libre 2 sensors can go through metal detectors at airport security. The FreeStyle Libre reader and the FreeStyle Libre Sensor can be exposed to common electrostatic (ESD) and electromagnetic interference (EMI), including airport metal detectors. However, it is recommended to notify the security officer prior to proceeding through airport security to request an alternative screening method if you are unsure about the type of security scan.
The Libre 2 sensors are safe to use around metal detectors, as they are not affected by the electromagnetic fields generated by these devices. The sensors can remain attached to your body while passing through metal detectors, and they will not trigger any alarms or cause interference. This is because the sensors are designed to be used in everyday life and are not expected to cause any issues with security measures.
However, it is important to note that the Libre 2 sensors should not be exposed to X-ray or millimeter radio-wave scanners, as these may damage the sensors and affect their functionality. If you are required to pass through a full-body scanner, it is recommended to inform the security officer beforehand and request an alternative screening method, such as a pat-down check.
Additionally, it is advisable to carry a doctor's letter or a 'Hidden Disabilities' lanyard to discreetly indicate that you may require additional support or an alternative screening process. Most security stations are well-educated about various medical devices, and calmly pointing out your Libre 2 sensors will usually prompt them to provide appropriate assistance.
Overall, while the Libre 2 sensors can safely pass through metal detectors, it is crucial to be cautious around other types of scanners and to communicate with security officers to ensure a smooth and safe screening process.

X-ray machines may affect Libre 2 sensors
However, some users have reported that their Libre 2 sensors have passed through X-ray machines without any issues. One user shared that they have flown numerous times with their Libre 2 and have never had any problems or adverse effects, even when going through X-ray scanners. They also mentioned that their device never stopped working due to X-ray exposure.
Despite these reports, it is always recommended to follow the manufacturer's instructions and request an alternative screening method when travelling with Libre 2 sensors. It is also a good practice to carry a doctor's letter or medical identification when travelling with diabetes equipment, as this can help discreetly communicate your needs to airport security staff.
Additionally, it is worth noting that some airports have Hidden Disabilities lanyards available for individuals who may need extra support. These lanyards can be a helpful way to indicate that you have a chronic condition, such as diabetes, and may require assistance during the security screening process.
In summary, while there are mixed experiences regarding the impact of X-ray machines on Libre 2 sensors, it is generally recommended to avoid X-ray screening for insulin pumps and CGMs. Users are advised to request alternative screening methods and carry relevant medical documentation when travelling with diabetes equipment.

Ask for a manual inspection and pat-down
It is recommended that you ask for a manual inspection and pat-down when going through airport security with a Libre 2 sensor. This is because the X-ray machines used in airport security will fry the sensors, rendering them useless.
To request a pat-down, inform the security personnel about your device and ask for a manual inspection. You can do this 1-2 minutes before your turn so that they can get someone to check you. When approaching the belt to put your belongings and shoes on, tell the TSA agent that you have a Continuous Glucose Monitor (CGM) and that it is sensitive to X-ray screening. You are not denying screening, but you do not want the machine to damage your medical equipment. They will then get another agent to take you to a semi-private area for a pat-down, a review of your belongings, and a residue swab of your hands and the CGM.
The body scanner may also kill the Libre 2 sensor, so it is best to request a pat-down to avoid this machine. You can also opt for PreCheck, which allows you to bypass the body scanner.
The Freestyle Libre reader can go through the airport X-ray screening system, but it is recommended that you power it off during take-off and landing. The wireless functionality of some insulin pumps and CGMs can interfere with aircraft communication and navigation systems, and you may need to remove your CGM and pump while in the air if your CGM cannot function without a wireless signal.
The manufacturer of the Libre 2 sensor will tell you that you should not take the sensor through either scanner and should ask for a manual inspection and a pat-down. Millimeter-wave scanners are safe for worn devices, but metal detectors can cause issues. These are the scanners where you stand up in the tunnel and raise your arms.

Carry a doctor's letter in your hand luggage
If you are travelling with a medical condition, it is advisable to carry a doctor's letter in your hand luggage. This letter should be on official letterhead with your doctor's signature, adding credibility to the document. It should include your name and flight information, a list of medical supplies or medication to be carried and their purpose, the approximate weight or number of items to be carried, and the name and contact details of your physician or medical practitioner. This letter may be useful in several situations, such as at airport security or a pharmacy.
When booking your travel, it is recommended to mention any health concerns and inform the relevant travel providers that you will be providing a doctor's note. This could include airlines, hotels, or travel agencies. Presenting the note politely and assertively, clearly explaining your needs and how the note supports them, can help set the stage for a smoother interaction. For example, if you need assistance boarding the plane due to a mobility issue, showing the note to the airline staff can ensure that the necessary arrangements are made.
It is important to obtain the doctor's note well in advance of your travel date and keep a copy with you at all times during your travels, including a digital copy on your phone for easy access. This is especially crucial if you are carrying insulin pumps and CGMs (Continuous Glucose Monitors), such as the FreeStyle Libre 2, as these should not be screened by X-ray or full-body scanners. Instead, you should request an alternative screening method, such as a pat-down check, and ask for your medical supplies to be hand-checked.
Additionally, if you are pregnant, some airlines may require you to have a specific pregnancy form or an official letter completed and stamped by your doctor or midwife after the 28th week of pregnancy. This letter should be dated as close to your travel date as possible and will cover your entire journey, provided you do not require any medical care during your trip.

Wear medical ID to identify yourself as diabetic
If you have diabetes, it is advisable to wear a medical ID bracelet at all times. This will allow first responders to identify your condition and address your medical needs in an emergency. Medical IDs are globally recognised by first responders and can provide peace of mind for those living with diabetes.
The American Diabetes Association recommends that all people with diabetes, especially those on medication that can lower blood sugar and cause hypoglycaemia, wear a medical alert identification bracelet. If your blood sugar levels drop extremely low, you could become confused or faint and be unable to speak. A medical ID bracelet will alert emergency providers that you have diabetes, allowing them to start treatment as soon as possible. Without a medical ID, first responders might attribute your symptoms to alcohol or drug use.
You can purchase a medical ID bracelet from companies such as MedicAlert and American Medical ID. These companies offer custom engraving on their bracelets, which should include any critical medical information that can protect and save lives in an emergency. This includes your name, medical conditions, allergies, medications, and emergency contacts. You can also select a Smart Medical ID Card, which uses QR code technology to provide access to your medical information.
When travelling with diabetes, it is recommended that you always wear your medical ID bracelet. You should also carry a copy of your full medical history and keep a doctor's letter on you or in your hand luggage. Many airports in the UK provide 'Hidden Disabilities' lanyards at their customer service desks, which discreetly indicate that the wearer may need additional support. You can also request an alternative screening method, such as a pat-down check, for your medical devices and supplies.
