These are always ordered on suspicious pts, and I'm curious if that is the case everywhere? Isn't there a privacy issue here. Certain things we need to get permission for, such as an HIV test, which I don't understand. What other tests do we need permission for?
Just to add something, when I get a urine drug screen, I always just ask for a urine sample, it's always hush hush, I've never announced to the pt that I need the sample for a drug screen.
