What does xanax show up as drug screen?

Xanax, or alprazolam, shows up as a benzodiazepine on a drug screen. If the drug screen has a separate toxicology section, it may show alprazolam metabolites specifically.

If they are testing for BZD's in general will there be any difference as to how each (clono & XANAX) show up on the tox screen?
