dul071 Wait! doesn't it take like a week or two to get the results back!?!? i chose to measure catecholamine levels because that may be more timely. but clearly i'm wrong +1

drzed Because a toxicology screen would both answer your question (e.g. that it could be amphetamine abuse) and would also pick up any other drugs that the patient might have been using. So even though the pre-test probability is high for amphetamine use, lets say it was something else, well then the tox screen would pick that up as well. Or lets say that it was simultaneous use of two drugs, same scenario. +2
