Does anyone know of a textbook or information source that addresses the following issues in drug testing:  sensitivity & specificity, GCMS, immunoassay.

Our hospital has a limited text collection and I'm limited on my knowledge of the subject.

The patron is a psych resident that needs info for a talk on drug testing for illegal substances.  He doesn't have specific tests or drugs.  

I've given him review articles and directed him to national Websites.  Didn't know if I'm missing something obvious.

Appreciate any help!
