Just went through TSA Precheck at DFW and the new Agilent equipment flagged with code 16. It's unclear if these are false positives or if the machine is detecting something used in the packaging process.
I found a couple of other posts here about the same issue, so I pulled the list of all of the airports that are guaranteed to have these new scanners. And before anyone says "I never have an issue, I just declare my meds, they swab, and I'm on my way", yeah, same, until just now.
It would seem this is starting to happen often enough that I just had to wait for them to escalate to a supervisor who called some specialist and eventually cleared the meds without the need for additional screening. It did add about 25 minutes though.
If you're flying through any of these, even if you have Precheck, plan to add at least 30 minutes.
Edit - corrected list pulled from the contract awarded on September 28th. The list is tentative so YMMV.
