I freak out everytime I take one of these pee tests. Years ago when I was about 18 I took a DOT Drug test required as a prerequsite to be employeed by an FBO that I had previously worked for. I got a call from the manager a few days later saying that my test came back positive for some sort of perscription pain killer. I was not on any medication nor had I ever taken a pain killer in my life.
I flipped out and called the lab in a fit of rage. 20 minutes later they call me and say they had mixed the result up and were sorry. You believe that!!!!
