I know post after post says that gender isn't ever tested during drug test but why do I find this on the internet?

9.2.1 Urine from a donor
You can substitute someone else's urine. Gender and approximate age of the sample can be detected, so take care when choosing a urine donor. Ask your urine donor (hopefully a friend you can trust) what drugs they've taken in the last month. They may have taken a false positive (or a true positive for that matter), and before the test, the examiner should ask you to list everything you've taken.


Taking a pre-employment e-SCREEN test this week and subbing my girlfriends...my first sub and I'm paranoid!
