A process designed to identify the presence of multiple substances of abuse within a biological specimen is a common practice in various settings. These procedures often utilize immunoassay or chromatography techniques to detect a range of illicit or prescription medications. For example, an employer might use this type of analysis to ensure a safe and productive work environment.
The employment of these screening methodologies offers several advantages, including promoting safety, deterring substance abuse, and ensuring compliance with regulations. Historically, such testing evolved from simple single-analyte assays to comprehensive panels capable of identifying numerous substances simultaneously. This evolution reflects increasing concerns about drug-related issues and technological advancements in analytical chemistry.
