If you are planning to travel with a FreeStyle Libre sensor, you may be wondering how to navigate airport security. It is recommended that you carry a doctor's letter that confirms your medical condition and any necessary treatments and medications, including the use of a sensor. This can be useful at airport security and during your travels. When passing through security, you should notify the officer if you are unsure about the type of scan you will be subjected to, and you can request an alternative screening method if necessary. While the FreeStyle Libre sensor can be exposed to airport metal detectors, it should not be exposed to x-ray or millimeter radio-wave scanners, as this may damage the device.
