Unfortunately, the testing labs offer a screen only and that is particularly true in employment testing. In that circumstance that simply relies on the initial screen, either positive
. Under that scenario it can't be determined if you used mouthwash or have been drunk for a month. So in the event they report simply a positive result
then you must immediately request a confirmation test.
There is always a chance that your test will be negative. With very low alcohol consumption it is a matter of timing. Just guessing, if there was a 10-12 hour time lapse from the time you took the nyquil it probably won't show. The time span on the glass of wine would be about 18 hours. (both assuming 100 ng cutoff)
It will also depend on the cutoff of the test, 100 or 500. At 500 cutoff your result could very well be negative, once again based on timing.
My problem with your case is that no one seems to know what's going on. Your production of the Nyquil and advice about drinking wine negates the need and purpose of the test. If that basic misunderstanding exists, what further errors in interpretation will occur?
Also, there are blood tests that can rule out heavy drinking. If it comes to that then you could request that assay.
