PCP is a dissociative drug with significant psychiatric and behavioral effects, including hallucinations, agitation, and sometimes violent behavior. Routine immunoassay screens may produce false positives from cross-reactive substances; LC-MS/MS provides specific identification.
This test is used to confirm presumptive positive screens, evaluate suspected PCP intoxication, and provide medico-legal documentation. Detection in urine is typically possible for 1-7 days after use. Sample type is urine.
