The IOC cutoff for a positive test is 150. MLB is 50. DOT is 50. Anything under those levels and the test is considered "negative". The urine screening is all pretty standard, basic stuff and information is readily available on the internet via different sites (which is where I got my info) on how testing is done and the different screening levels by different organizations. It's not a question of MLB using a cheaper test.
I'm not questioning the NFL's right to test for pot, or any other organization, public or private. What I'm questioning is the NFL's insistence on a considerably tighter standard (TDTORange addressed the standard pretty well). While you may think the NFL standard is the same as the others, it isn't, and this has been backed up by numerous experts on the subject over the last 4 weeks since the Josh Gordon suspension was first announced.
there is a lot more information out there and lots of different methods in which they use.
some are very much more accurate than others and others only score a negative or positive at certain levels and other like LC/MS and GC/MS can actually give the accurate amounts in your system.
I had to Pee in a cup once that instantly tells you pass/fail and that was a 50ng/l test at a power house in Albany. And if you failed that test then they sent you a certified lab that gave you test that broke down to the actual levels. Sometimes it's all about saving the company money up front.
Some testing facilities will not accept clear urine and the Nuclear testing will take that clear urine and they will find it if it is in there. I have taken countless tests and all came back clean. Just ask the person testing you about their methods I always do. YOU HAVE THAT RIGHT
