You can be screened without having to empty or expose the ostomy pouch during Advanced Imaging Technology (AIT), a walk-through metal detector (WTMD), or a pat-down screening. Please inform a TSA officer that you have an ostomy pouch before you enter the screening area. The ostomy pouch is subject to additional screening and may require you to conduct a self pat-down of the pouch outside of your clothing, followed by a test of your hands for any trace of explosives. You may also undergo a standard pat-down of areas that will not include the ostomy pouch.
