Do they ONLY run the GC/MC if there's a positive result? Like I said, I still don't know what the "w/ts" meant so I thought it might be possible they do both the screen and the test
rsad Reviewed by rsad on . Question about preemployment Hello I have to take a preemployment test at Quest labs within a few weeks (as soon as tomorrow) and I definitely would not pass (smoked yesterday, wasn't really sure when i'd be called in). Its for a summer job I've been at for a few years now but now I'm going back earlier. Usually I would just stop for 3 weeks and I'd be clean. Now I either want to dilute or substitute. It's a mandated drug test through the coast guard, which is what makes me question using substitution. It's a split sample Rating: 5
