What is the workplace testing cutoff level for PCP?

The workplace testing cutoff level for phencyclidine (PCP) is established at 25 ng/mL. This specific cutoff level is set to ensure that positive test results indicate a significant presence of the drug, minimizing the likelihood of false positives due to other substances or environmental exposure. Cutoff levels are critical in workplace drug testing protocols, as they serve to distinguish between legitimate use or trace amounts and potential impairment or abuse. A level of 25 ng/mL has been determined through research and consensus within regulatory bodies to be an effective threshold for detecting PCP in a sample while allowing for the practical concerns of testing reliability and accuracy in a workplace setting. Therefore, understanding this cutoff level is important for both compliance and safety in occupational environments.
