BTW I think you're wrong about it going straight to GC/MS. I have never seen a test go straight to GC/MS. They send them through immunoassay first then non-negatives are confirmed with GC/MS. They make more money this way and it's kind of written into the regulations and procedures this way regardless of who is testing the sample, Labcorp, quest, Knoll, etc. Sorry I used to have the link to this part of the procedure on the history on my computer but it go wiped out. A collector I know also says this, that they only go to GC/MS if there is a non negative on immunoassay first. It might say GC/MS on the chain of custody form but it still gets immunoassay first.

Good job on subbing.
FakeBoobsRule Reviewed by FakeBoobsRule on . GC/MS Testing at Labcorp Monday I am being tested for a new position at Labcorp and upon doing some research it appears they do the GC/MS test right off the bat. I am 5'4, weigh 100lbs, extreme metabolism and have been a fairly constant smoker forever now but will have 72 hours clean upon testing if I do use my own. I'm thinking of substituting just to be safe, however, a friend of mine who tests for parole uses Ready Clean with great results. I'm afraid that's because they do the simple cup test vs GC/MS. Any ideas? Rating: 5
