Hi, so here's my situation. I have a DOT pre-employment test.
I tested the first time, 20 days clean and apparently the sample showed up to the lab with the container not sealed, causing the test to be canceled.

After I had given the first test, I smoked. Bad choice. But the second test was a week later, I used canadian QuickFix 5.7-1 to be sure I'd pass. The test showed up as having 'Immunoassay interference' and had a result of 'canceled'.

Currently my future employer is talking to the MRO to get more details and after personally speaking with the MRO she said I'll likely be asked to test again. It has been a week again since I smoked and I plan on using a detox drink, assuming I'm asked to test again and don't just get denied the job.

Here's some information about me: I'm 5'6'' 150lbs, and I have a moderate metabolism. My smoking history is, I was 20 days clean, smoked once, one week clean, smoked once, and now I am one week clean again.

My questions are:
Has anyone ever had that problem with QuickFix on a DOT test before? What happened if you did?

Do you think I'll pass this third time? I know it's impossible to tell really for sure, just looking for some reassurance in either direction. given DOT testing, is it likely it'll come up dilute if I take a detox drink? I'm unsure how that affects creatinine content of my urine.

Any suggestions as to a course of action? or any other information you'd like to better tell? I don't personally have a copy of the result, I only spoke with the MRO over the phone.


I really appreciate any insight you may have!!
