Abstract
Rational drug-testing programs attempt to balance the need for accuracy of the process with the need to preserve the rights and dignity of the people being tested. U.S. Department of Transportation regulations prescribe the specifics of how urine specimens are to be collected, how to inform the specimen donor of the process to which he or she will be subjected, and certification of laboratories by the National Institute of Drug Abuse. These guidelines are an effort to assure that each collection site and each laboratory testing the urine of employees adheres to certain basic standards of quality control.
