thanks for the input guys. i think ill just go ahead and ask my friend to come in for me. he looks a lot like my id picture, and according to you guys, they dont check very meticulously. just in case i decide to sub the urine, i wanted to know whether i can use real urine as easily as synthetic; if i can warm it up and cool it down without a problem. and also, if any has had an experience in which people at labcorp really took time analyzing the id photo or something, please let me know. thanks guys
