Urinalysis for detection of drug abuse is widely used in pre-employment screening and correctional administration. Substantial protocols have been developed in these applications of drug testing to minimize the impact of any given vendor on results. Much less documentation exists for epidemiological drug testing programs such as the Arrestee Drug Abuse Monitoring (ADAM) program. This paper explores the impact that changes in laboratory vendors and data collection methods have on drug testing results. Here, the authors report the findings from a comparison study. The project was designed to determine the consistency of the urinalysis results when the same urine specimens were analyzed by two independent laboratories.
