PAB is right.

Gender and age are totally irrelevant in the world of drug testing. Drug testing devices are unisex - they have no ability to determine who the sample came from - they only detect the presence of drug metabolites. With that being stated, any human sample can be used as a sub as long as it is known to be drug-free and not overdiluted.
Burnt Toast Reviewed by Burnt Toast on . First Time Subbing (Freaking Out)!! So, I recently graduated college, and got a great offer. I did my UA on Wensday 5/22. I used a friend of my daughter's urine and she is 12 yrs old. I took the test at Medgroup. The temperature was right, but I havent gotten a phone call yet. The nurse told me no news is good news, but I'm still nervous as hell. How good do you think my chances are? Rating: 5
