A member asked:
What could cause a false negative on a drug test for barbiturates?
A doctor has provided 1 answer
The typical reason: is that the urine metabolite was below the "cutoff" levels for the screening which would not then be subjected to confirmation. It is not that barbituates were not in the sample, but that they were below the "positive" quantitative level for confirmation. Barbiturates are not on federally mandated testing so the cutoff level is arbitrarily assigned.
