Hey everyone,
I’ve got a DOT urine drug test coming up in about 2 weeks and I’m trying to get a realistic read on where I stand.
Background:
I was completely clean for about 4–5 months
Had a very small relapse in June 15,16,17th (a couple hits over 2–3 days)
Been clean again since then
What I’ve done so far:
Multiple at-home THC tests → all negative
(these are the standard 50 ng/mL cutoff tests)
Took an instant lab test → negative
Also took a lab test that was sent off that was NoN DOT look alike and I even passed it , it was negative as well.
( 7 test total in 17 days)
Planning to take a lab quantitative test soon just to see levels
From what I understand about DOT testing:
The initial screen cutoff is 50 ng/mL THC-COOH
If that screen is positive, they run a confirmatory test around 15 ng/mL (GC/MS or LC/MS)
So even if you pass a home 50 ng test, I’m trying to understand how that translates to DOT lab confirmation levels
My questions:
MY MAIN QUESTION, Do they automatically test you for the 15Ng cut off along with the 50 NG ? Because I had a guy tell me they test for the 15Ng automatic on THC but even on the FMCSA website it said different , and now I’m skeptical about it .

If I’m consistently negative on 50 ng tests, does that usually mean I’m also below the confirmatory level?
How often do people pass 50 ng but still fail at lower lab confirmation levels?
Does having ~2 more weeks realistically make a big difference in dropping below both levels?
Am I likely in the clear or still in a risky window?
Just looking for honest experiences from people who’ve actually been through DOT testing. Not trying to do anything shady—just trying to understand where I realistically stand before I go in.

By the way ( I didn’t think I was going back to work but for personal reasons , now I have to , my wife is a RN but going back to school for nurse prac and we have autistic son , who goes to school even through summer time , and I thought I was going to be able to relax , and we have no help ) that’s why I’m in the situation.
