I'm going to use the Whizzinator to pass my urine test. It's a very good job and I cannot afford to fail this DT. I will not have smoked in 25 days but I cannot risk it. Each time I get a strip test from WalMart I only get a faint line. Anyhow, my question is can the testing lab (Lab Corp) tell the difference of female or male urine? From what I read no but just want to make sure. My wife is on birth control as well. Can they tell anything from that. I also have a prescription OFF TOPIC DRUG. That will show up I'm sure. But the prescription should cover that. Just VERY nervous!!
