UA tomorrow, can I sub my wife's urine for 5 panel Pre-employment screen? Need HELP!

Around Thanksgiving last year I thought I had a job offer coming down the pike. So stayed clean for about 1.5 months. Time went by after interviews, and around Christmas, I assumed I would not get offered the job, and happy a holiday toke session.

As Murphy and his laws would have it I've been contact as recently as today to take a screening tomorrow. Obviously my only hope is to sub, I am thinking of using QuickFix which has worked for me in the passed. But how about using my wife's urine for subbing?

Will a standard 5 panel test indicate gender? She is not a smoker whatsoever, and would be perfect to provide for me IF I was sure the facility did not routinely check for gender characteristics in their test.

I have not been told which facility I will do my UA and physical at yet. Please let me know about the gender thing, so I know whether I have to use synthetics or not.

The question about gender testing has been answered many times throughout the DT forum.
Do an Advanced Search using the terms "gender test genetic". You'll have your answer then.

FYI: 5 panel test = testing for 5 types of drugs. But for the purposes of this forum, the only drug you need to concern yourself is THC.
