Computerized systems designed to detect and perform quantitative analysis of body fluids to detect one or more of a group of drugs that either are illegal or are frequently taken for nonmedical purposes (i.e., drugs with a high potential of abuse). Drugs-of-abuse include but are not limited to cocaine, lysergic acid diethylamide (LSD), and morphine; the test usually does not include drugs that may be taken as prescription drugs (e.g., barbiturates). The system typically consist of a personal computer and peripherals (e.g., printers, monitors), urine sampling devices that prevent tampering, a photometric reader to analyze the samples, and usually an internet-based link to provide automated assessment and response when negative results are obtained. Some systems may include a pre-screening assessment based on a scanning of the eye that assess central nervous system abnormalities that may be caused by drugs of abuse and require further urine tests. The software package that controls the process is typically operated through the internet connection; the system may allow the introduction of additional results from laboratory and breath tests (e.g., alcohol), and/or manual data obtained from physical examinations. Drug-of-abuse screening test systems are mainly intended for use in occupational health facilities for employee screening as well as for use in emergency situations when use of drugs-of-abuse may be involved.
