Can anyone tell me what "0 10GCMS Drug Abuse Panel 10(GC/MS)" exactly is?

[ringle101]

From what I understood most of them listed the threshold at the front, like 10-20 meaning a ten drug panel at the 20ng level. Does the 0 mean that it's at a 0ng threshold? The test I took didn't include an immunoassay at all and went straight to the GCMS as far as I can tell.

All urine testing methodologies have some sort of cutoff threshold, so there really is no "zero-tolerance" test.
The test youve took is a 10 panel screen with a confirmation GC/MS. The assay screen is always performed first. It would be too cost-prohibitive on the part of both the lab and client to run the GC/MS as the primary analysis.
Therefore, the GC/MS is only used on any of the panels that have tested "non-negative" on the initial screen. It would run into hundreds, if not thousands of dollars to run the GC/MS on all of the drugs on a given panel (particularly in this case, the 10 panel).

Drug tests are just not conducted in that manner.

That makes me feel better. On my urine analysis form that I signed it only listed that GC/MS and didn't say anything about an immunoassay, so so that's what had me worried. The test is for a (student) job at a hospital that has their own on-site drug testing. Even with that in mind you don't think there's a chance they'd jump straight to GC/MS?

You'd have to remember (or at least, you'll learn in time after racking up some years in the corporate rat-race) that ALL businesses (that even includes the Health Care field) have a bottom line to look after. No employer in their right mind of business would imperil that bottom line by testing the urine of every Tom, Dick, or Harry on the payroll, using the GC/MS right out of the chute. They would not last as a business - especially if they have a large payroll.
