A comprehensive laboratory analysis is used to detect a wide array of substances within a biological specimen, commonly urine. This analysis is designed to identify the presence of twenty-one distinct classes of drugs, or their metabolites, exceeding the scope of many standard drug tests. As an example, such a test might screen for prescription opioids, benzodiazepines, barbiturates, amphetamines, cocaine, marijuana, and phencyclidine, along with extended opiates and synthetic opioids, and other substances subject to abuse.
The extensive nature of this screening provides a more thorough assessment of potential substance use, offering a broader perspective than less comprehensive panels. This level of detail is particularly valuable in situations where a wide range of substances might be of concern, or where it is necessary to identify potential poly-substance abuse. Historically, simpler tests were sufficient, but the increasing availability and diversity of both prescription and illicit drugs have necessitated more advanced and extensive screening methods.
