    Does anyone know what the DOT cutoff level is for THC? I passed the at home test from Walgreens.Whats the cutoff level used on these sort of tests? Also,if I wake up today and test my first void of the day and pass the at home test does that mean I'm gonna pass the test for DOT? Do they send off all DOT tests for confirmation or just use the same type of test that I have already passed?Thanks for your time !!!!

    On DOT tests, the initial screen has a cutoff level of 50 ng. If you test negative on the initial screen, the test is over as a 'passing' status and no GC/MS will be done.
    As long as your home test had a cutoff level of 50 ng (which most do, BTW), you'll pass the initial DOT screen as long as you remain "clean" from here on up to deadline.
    :cool:
