In the past 5 years, a growing concern over the use of illicit drugs in the workplace has led to an interest in urinalysis as a way to detect and deter drug use. This monograph provides information that will assist those involved in the planning or implementation of drug testing programs in making informed choices. Articles include: (1) "Establishing a Urinalaysis Program--Prior Considerations" (Richard L. Hawks); (2) "Drug Testing Programs" (Robert E. Willette); (3) "Choosing a Laboratory" (Robert E. Willette); (4) "Proficiency Testing and Quality Control Programs" (Robert E. Willette); (5) "Specimen Collection and Handling" (Joseph E. Manno); (6) "Analytical Methodology" (Richard L. Hawks); (7) "Accuracy in Urinalysis" (Robert V. Blanke); (8) "Interpretation of Urinalysis Results" (Joseph E. Manno); (9) "Implications of Drug Levels in Body Fluids: Basic Concepts" (C. Nora Chiang and Richard L. Hawks); and (10) "Examples of Specific Drug Assays" (Richard L. Hawks and C. Nora Chiang). Drugs discussed in the section "Examples of Specific Drug Assays" include marijuana/cannabinoids, cocaine, amphetamine and methamphetamine, opiates, phencyclidine, alcohol, lysergic acid diethylamide, methaqualone, barbiturates, and benzodiazepines.
