A fast-response analysis of a biological specimen, such as urine, saliva, or blood, designed to identify the presence or absence of specific substances, including illicit narcotics and certain prescription medications, in a significantly shorter timeframe compared to traditional laboratory testing. These analyses often utilize immunoassay techniques to provide preliminary results within minutes. For example, an employer might use one to screen potential hires or to assess current employees following a workplace incident.
The value of such assessments lies in their speed, affordability, and ease of use, making them valuable tools for situations demanding prompt decisions. These scenarios include pre-employment screening, post-accident investigations, and monitoring individuals in substance abuse treatment programs. Historically, these immediate evaluations have helped organizations maintain safety standards, reduce liability, and ensure compliance with regulatory requirements.
