I was sent to the hospital by my employer for a drug test yesterday. I'm worried they're going to skip the initial immunoassay test, since it appears the tests ordered are GC/MS confirmation tests with reduced cutoff levels.
One of the test codes is 149. The description of this test code on the test catalog portion of the MedTox website (MEDTOX : Test Catalog) reads:
"Quantitative result is marijuana metabolite measured as 11-nor-delta-9-carboxy-THC (carboxy-THC) by gas chromatography with mass spectrometry (GC/MS). Results are reported to limit of quantitation of the assay." I'm not sure if I should take this as meaning there's an assay first, or just the GC/MS test.
The top of the form I received reads "Non-Regulated 5 Part Drug Testing Custody and Control Form" with a MedTox logo. The test ordered are '149 THC', '831' coc, '9376 opi', and then it has an additional box that says other without a barcode beneath.
I'm very curious if anybody can put my mind at ease or offer some insight? I think I'd beat a 50 ng/ml cutoff but I'm not sure about a 15 or lower.
Also, what is the average amount of time to hear back from an MRO if a result is positive?
Thanks in advance.
