I understand that. Is the Lab charging for uneccissary test? If the confirmation test is under 50 that means there wasn't a need for it in the first place right?

Not sure what youre trying to ask here.

The confirmation test (GC/MS) is used only if the urine sample registers a "non-negative" for any of the drug panels on the initial I/A screen. So if a urine sample tests negative for all of the drug panels on the I/A, the test is over as a "pass" - no confirmation test is performed. It would make no economical sense to both the lab and client to run a confirmation GC/MS test if a urine sample tests negative for all of the drug panels on the I/A. It would run into the hundreds, if not thousands, of dollars to run the GC/MS on all of the drugs on a given panel.
Drug tests are just not conducted in that manner. Like all businesses, labs are into making a profit and they are not going to run unnecessary tests that could eat away at their profit margin.

And no employer in their right mind of business is going to spend that kind of money on such unnecessary tests, especially if they have a sizable number of workers on the payroll.
Burnt Toast Reviewed by Burnt Toast on . Drug Test violation?????? I recently took a pre employment drug test. I received results that I failed with 44ng ml. If my cutoff was 50ng ml for the initial test, why was it sent for confermation testing? Shouldn't my test been reported as negative with a result of 44ng ml with a cutoff 50ng ml? Initial test cutoff-50ng ml Confermation test cutoff-15ng ml My results: Initial test-44ng ml Confermation test-44ng ml Rating: 5
