I have to take a drug test for a management job. I will arrive on a tuesday and the test will be wednesday morning sometime. I am not for sure how long urine is good for since i am going to use a substitution method. I have a Urinator so all that is covered but my problem is i have to be there on tuesday night. This leaves about 2 and 1/2 hours drive time and then at least 10-15 hours till test time. WIll the urine be good at room tem p till then and if it isnt, what would be the best method to freeze then reheat then stick the pee in the urinator.
question 1 how long is urine good at room temp.
question 2 can i freeze the urine, store in ice for the ride and night before then heat in a microwave or other rapid method without ruining the sample.
Thanks.

ok i just read the thread on freezing urine so i now know this is ok, i also see that it is not recommended to use a microwave, seeing this my new question is how do i rapidly rewarm the urine if microwave isnt possible.

i see that it is suggested to use a coffe mug with coffe in it which is fine mut does anyone know the time frame here to warm it up to an acceptable temp so the uirinator i have can maintain?
