From what I understand, the GC/MS is usually only performed when to confirm a positive result on the immunoassay. If you're neg on the first part and your urine passes an integrity check for creatinine, specific gravity, adulterants (from detox drinks), etc., you're good to go.

I read how a GC/MS test is performed and it sounds pretty darn time consuming annd expensive. Quest and LabCorp would rather overcharge companies and other hysterical shrews millions and millions of dollars for dip stick tests, than take up their valuable time and equipment confirming negative results.

not sure what this means......

are they saying that immunoassay is a screen? or GC/MS is a screen.... i didnt see the words screen or test in this....

what do you make of this 1toke?

Immunoassay would be the screen and they confirm (drug test) with the GC/MS. That is the way I have always understood it.
As sec3 says.........don't worry if I am wrong someone will correct me.

The GC/MS is what rules out any false positives. Buzzby and FakeBoobsRules have both posted how many THC metabolites that each of them test for. I believe it is screening 36 or 39 and GC\MS 1. I just guessed at the numbers try a search for THC metabolites and maybe you can find the exact deal if you are interested.
Have a good one.

Hear ya go.......post#5. that will get you started.
