What is defined as a lawfully administered test to detect the presence of a controlled substance?

A drug test is defined as a lawfully administered test to detect the presence of a controlled substance. This encompasses a range of testing methods that can be utilized in various settings, including workplaces, legal situations, or medical evaluations. The primary purpose of a drug test is to ensure compliance with legal and safety regulations by identifying whether any prohibited substances are present in an individual's system.

The terminology around drug testing can be nuanced. While a substance test and a standardized drug test refer to specific approaches or methodologies, the broader term 'drug test' effectively captures the essence of detecting controlled substances. A field test typically refers to preliminary tests conducted on-site or outside of a laboratory setting, which may not cover the entire spectrum of drug testing methods and may not always result in legally admissible outcomes. Therefore, when considering the most comprehensive and universally accepted term for this type of evaluation, 'drug test' is the most accurate choice.
