So i had to take a drug test for the ACE program, i had nothing in my system except THC from the day before the test, i drank loads of water before the test and the test came back negative, but the test line for THC was faint so she sent it to the lab to confirm, and im just wondering if the dip test she did is as accurate as the labs? i dont think it'll be the 15 nl/ml test or whatever the unit of measurement is.
