As an update, I didn't get the job.
I requested a copy of my drug screen from the company but they said they don't give that out. That maybe the lab does. To the best of my knowledge though the lab doesn't give out the detailed results except to the company.

Here's a couple final notes.
The name of the lab was Lexis Nexis Business screening solutions
The synthetic I used was QuickFix 5.7-1 Batch# Canada-P6MM-13C

It is unknown if the result actually came back as synthetic. The lab claimed it was "immunoassay interference" with a final result of 'canceled'.
un1bomber Reviewed by un1bomber on . Curious situation, testing for the third time!! 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'.
