I've used femme urine to pass a drug screen several times. They're simply looking for the presence of drugs. As is mentioned quite frequently on here, most employers test due to insurance purposes. They're usually going the cheapest route possible and it's very unlikely that the test your potential employer is going to administer is going to be extensive enough to report the sex of whoever produced the sample.

Get your ol' lady to piss in a condom and you're good to go! :thumbsup:

Things to remember: Carry a bag to place your empty rubber in once you've filled the cup. Bring a safety pin to pop it. And bring a napkin, as you're not allowed to use any water from the tap until you've turned your sample in.
