I now have twice as much work to do because of blindman's guesses and inexperienced answers. Did the word "blood" escape blindman when you were looking up BUN? That is because the test is run on blood not urine. I am pretty sure Crt is not creatine clearance either which is usually abbreviated CrCl. This little string of codes almost describes a blood test and not a blood test for drugs. You very well may have a drug test but you might also have a blood test too. I would prepare for a urine test and that is that. If they told her that she has a urine test coming, she better get ready for it. Any chance she is getting a physical too? No, the Duzz it isn't going to affect BUN.

Blindman, just because you got clean in 3 weeks doesn't mean everyone else will too. The half-life of THC ranges from 0.8 days to 10 days depending on the person. Then there is smoking history to take into account.
FakeBoobsRule Reviewed by FakeBoobsRule on . 5+Crt+pH-BUN = Urinalysis, right? Just got the form for our test (it will be through Labcorp) and it had that (5+Crt+pH-BUN) written on it, and also some other indicators that it was a urinalysis (ie: a section to record temperature 90-100). But they said on an intro letter that they follow DOT standards (even though this is not a DOT job) and so I just wanted to run it by you pros and make absolute sure it was a urinalysis and nothing more, as I'm unfamiliar with how DOT conducts their tests. Also, based on that equation Rating: 5
