According to here: http://usmilitary.about.com/od/theorderlyroom/l/bldrugtests.htm
The screening level for THC is 50ng/ml, yet the confirmation level is 15ng/ml.
Most over the counter Drug tests (i.e. First Check, etc) cut off at 50 ng/ml. My question is what the hell's the difference between the screening level and the confirmation level? If i pass a drug test bought at home/given to me by a military recruiter, and still have at least 15 ng/ml in my system will i pop automatically at MEPS? Or is that secondary measurement only used if you fail your preliminary test?
