Definition - What does 4 panel drug test mean?A 4-panel drug test is a drug screening procedure involving the analysis of a urine specimen to detect residual metabolites most commonly linked with the following substances: cocaine, marijuana, methamphetamines, and opiates. However, employers can enlist a customizable 4-panel drug screen tailored around their preference to confirm whether an individual uses a particular substance based on different classes/subclasses of drugs; for example, amphetamines, barbiturates, benzodiazepines, and propoxyphene.

For many employers, a urine sample is a convenient, cost-effective measure performed in line with a 4-panel screen designed to identify the presence of drug metabolites found in the system from a current or potential employee. While urine drug screens can provide quick and accurate results, employers are responsible for determining the circumstances outlined for individuals to submit to a 4-panel drug test. For example, the Canadian Model for Providing a Safe Workplace, aligned with the U.S. Department of Transportation (DOT), utilizes a drug class/subclass matrix for identifying drug metabolites with their corresponding cutoff threshold range values.
It is imperative to follow the necessary steps required when conducting a 4-panel drug test which, depending on the situation, involves an allotted time interval (i.e. a timer), regulated temperature, and a prompt turnaround on test results.
