330			_aEmployee drug screening - detection of drug use by urinalysis - questions & answers: Why do companies use urine screening? How many companies are using preemployment screening? Is urine screening for drugs legal? How often should employees be screened? What about individual rights, privacy, and confidentiality? Who should set up a drug screening program? How does one develop a policy? What level of drug in the urine indicates an individual is impaired? How reliable are urinalysis methods? What does laboratory quality assurance mean? Many reports have appeared in the news media about legal cases in which experts have questioned the validity of a urine assay result. Does this indicate that the assay methods are not sufficiently reliable for broad application? What are the primary methods being used for urine screening? What are "confirmation assays"? What is the preferred method for confirmation of presumptive positives from initial urine screens? What do assay "sensitivity" and assay "cutoff" mean? How can false positives be eliminated? How frequently do false positives occur? Are rigorous and costly laboratory procedures always necessary? Can passive inhalation of marijuana smoke lead to a positive urine even if the person did not smoke a joint? Can time of previous drug use be determined from analysis of urine? Can the level of "intoxication" of an individual due to marijuana use be gauged by urinalysis? Can his or her "use patterns" be determined? How long after use can cocaine/heroin/phencyclidine be detected by urinalysis? How long after marijuana is used can such use be detected? If a urine sample is negative a day after a positive sample, does this mean the first result was wrong? How are the results of a urine drug assay expressed? What adverse health effects can be correlated with the presence of marijuana metabolites in urine?
