Hello, I just took my first drug test using substituted urine. Everything seemed to go fine, but there is something that still nags at me. On the way to the clinic I decided to heat my sample with my car's defroster. I didn't realize that it would be so effective. I heated it quite a bit higher than I planned to, somewhere around 111 and 112 degrees. I let it cool back down before going in. I was just wondering if heating it too much would in some way be damaging to the urine, and if so is the temperature I got it to too much. I'm probably just freaking myself out. Can anybody help put my mind at ease?
