In many cases, a sample is automatically sent to a lab for both the initial screen as well as the confirmation test (confirmation test being used due to a non-negative on the initial screen). The reason for this is because many collection facilities are not certified to conduct any analysis - they are only certified to collect the specimens.

Hey everyone, I just wanted ask a hypothetical question about a person passing a drug test... :1baa: Say this person was a pretty heavy user, like nearly every day for months at a time, with a week off here and there... but relatively healthy and active (5'6, 130lb)... Say they stopped everyday smoking April 23 (alittle over a month ago)... BUT relapsed and split a modest blizzie with a friend exactly 3 weeks and 2 days ago today... Say this person has consistently tested negative Rating: 5
