    Important to know

    If you are scheduled for a urine drug testing, it is very important to know what kind of testing it will be. There are multiple variations of a urine drug test and not all of them are as simple as they seem. Dip sticks and panel testing are the cheapest ones, so many companies opts out for those types when employee drug testing is needed. However, if there is a liability involved, and they need to make sure that all the basis are covered, a more comprehensive urinalysis may be performed.

    Detection time varies for different substances, and that is one thing to keep in mind. Another – test sensitivity. According to the lasted updates regarding DOT urine drug testing, the cut-off levels for the initial testing are the following: marijuana metabolites (THC) 50 ng/ml; cocaine metabolites (could be several different ones, including benzoylecgonine) 150 ng/ml; opiate metabolites (codeine and morphine) 2000 ng/ml and 6-acetylmorphine 10 ng/ml; phencyclidine 25 ng/ml; amphetamine and methamphetamine 500 ng/ml, and MDMA (Methylenedioxymethamphetamine) at 500 ng/ml.

    Results that are registered below the cut-off levels are negative; but if results are registered at or above the specified cut-off levels – the same sample needs to be re-tested at the confirmatory testing, which is more sensitive with lower cut-off levels. Marijuana metabolites (THC) drops to 15 ng/ml; cocaine metabolites drop to 100 ng/ml; opiate metabolite codeine drops to 200 ng/ml; amphetamine and methamphetamine drop to 250 ng/ml, and MDMA also srops to 250 ng/ml. As you can see, confirmatory drug testing is more scrupulous testing and leaves no place for an error. Make sure are you are properly prepared if you have DOT drug testing coming up.
