What are they looking for when they swab you at the airport?
Why is TSA swabbing your hands and bags at airport security? TSA will swab the hands of passengers as well as their luggage in order to detect traces of dangerous explosives.

TSA states that “officers may swab an individual's hands, mobility aids, equipment and other external medical devices to test for explosives using explosives trace detection technology.”
Does airport swab test for drugs? They are not testing passengers' DNA, testing for viruses or illnesses, and the testing equipment does not test for narcotics. But be warned — an additional search that turns up drugs can get you into trouble, and refusing the swab test can get you referred for additional screening.
As shown in more detail below, this additional screening could be caused by things like: Your name matching a name of interest in a database. You raising suspicions while going through airport security. Your bag getting flagged when going through an x-ray machine.
Airport body scanners alert the TSO to threats—mainly weapons such as knives, guns and explosives. They are designed to detect “metallic and nonmetallic threat items,” according to the TSA. Those are things like explosives or knives made out of materials other than metal, like ceramics, says Malvini Redden.
If it is illegal locally, they will notify airport or local law enforcement, and detain offenders. If it is legal locally, they will force you to dispose of it because it is still illegal federally.
Various nitrates are often used in the making of explosives (e.g., trinitrotoluene, a.k.a. TNT) and they're checking to see if you've been handling any recently. I find it interesting that they were checking hands—perhaps that's more accurate than some of the other sampling sites they've used in the past.
Clothing and Fabric: Certain types of clothing, fabrics, or folds in clothing can create the appearance of an anomaly in the crotch area on the scanner's image. Loose-fitting clothing, heavy fabrics, or items like belts, buttons, or zippers in that area can trigger alerts.
How sensitive are airport swab tests? The good news is the test is highly sensitive. The bad news is nitrates and glycerin are found in some harmless everyday products, so you could test positive. Getting swabbed doesn't seem to be particularly random.
The TSA largely looks for physical evidence that a passenger could be a threat, so they'll generally have no reason to search through the data on your phone. After all, they're the Transportation Security Agency, not a detective agency. Even if they did have reason to want to access your phone, they'd need a warrant.
The airport scanners have no problems finding the pills that you are travelling with, liquid form or not. In case of travelling with pills in liquid form, in your carry-on baggage, they must not exceed 3.4 ounces/100ml.
If you're trying to fly with edibles, stash them in a resealable fruit snack or gummy bear pouch — something that's also not a permeable plastic ziplock bag. If you use a ziplock bag, your edibles will scan as orange, which alerts TSA of “biological material.” Fortunately, most vape pens can pass as eCigarrettes.
Can you see a tampon during an airport body scan? This is a frequently asked question on Google, and if it's something you're worried about, you can breathe a sigh of relief. Airport body scanners can't see inside the body and therefore can't detect a tampon on a TSA female body scan image.
While checked luggage is not routinely searched for drugs, there are still measures in place to identify suspicious or prohibited items, and if illegal items are found, there could be serious consequences.
The TSA drug tests are highly accurate, but they're not 100% accurate. Several things can affect the accuracy of these tests, including: The amount of urine you gave.
What does it mean to get “flagged” by TSA? Getting “flagged” by TSA could mean a few different things. But for the most part getting flagged by TSA just means that you or your personal belongings will experience some type of additional screening when going through the airport.
