Phencyclidine (PCP) is a dissociative drug that was once used as an anesthetic but is now strictly a drug of abuse. Within a DOA 5-Panel, this test screens for recent ingestion of the substance. PCP acts on the central nervous system, causing hallucinations, agitation, and potentially violent behavior. Monitoring is essential in emergency settings for patients presenting with altered mental status or in occupational/forensic drug screening to ensure safety and compliance.

Why Context Matters

Immunoassay screens for PCP are notorious for cross-reactivity. Common substances like dextromethorphan (over-the-counter cough medicine), diphenhydramine (Benadryl), and venlafaxine can trigger false positives. A second opinion using GC/MS or LC-MS/MS is mandatory for confirmation of a 'Positive' screening result.

Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
