This laboratory procedure analyzes a urine sample to identify the presence of multiple substances, commonly drugs of abuse or their metabolites. The assay employs various analytical techniques to detect and quantify specific compounds, providing a comprehensive profile of substance use. For instance, it can simultaneously screen for amphetamines, opioids, cocaine, benzodiazepines, and marijuana, among other substances.
Such testing plays a crucial role in various settings, including pre-employment screening, workplace monitoring, clinical toxicology, and substance abuse rehabilitation programs. Its benefits include facilitating informed clinical decisions, deterring substance abuse, and ensuring compliance with legal or regulatory requirements. Historically, these analyses have evolved from simple single-analyte tests to sophisticated multi-analyte panels, offering enhanced efficiency and scope.
