Whizzinator questions

Ok so I am getting a new job and I was told that I have to take a drug test by Monday. This job is the opportunity of a lifetime and I really don't want to fuck this up. I bought a Whizzinator on Tuesday and had it rushed delivered. I used it during my job interview on Thursday just in case and everything seemed to work fine but the tempeture strip said 102 degrees which is too hot for drug tests. Has anyone taken a test at Lab Corp? Has anyone used a Whizzinator at Lab Corp.? Is it ok for the tempeture strip to say 102 degrees? Any help would be greatly appreciated.
