Fear has it that the pH could have been thrown off by raising and lowering the heat of the urine and by occasionaly opening the cap to check temp.
This would not have any effect on any of the urine constituents being tested. The only time temp has any effect is if the urine sample was brought to a boil.

And theres no sensible reason to bring a urine sample to a boil when the acceptable temp range is 90-100F.
Burnt Toast Reviewed by Burnt Toast on . A little re assurance would be great Here's the situation my friend is in..... If a person took a DOT/SAMSHA test, and in the temp box they marked "yes" for 90-100, but in the comments they wrote 92 (they did this before when it was 94 and there was no problem) and also wrote something along the lines of "very strong smell", will there be issues at the lab or MRO ? One would assume that once it's bagged and initialed it's good to go, right ? If the collector wasn't going to accept the sample, a re-test should have taken place Rating: 5
