Specimen Collection Criteria

Collect: 50 mL random urine in a screw-capped container (preferred) or other sterile collection cup. (Minimum: 30 mL)

• Refrigerate the specimen immediately after collection.
• Record the exact time of specimen collection on the container or in the computer system.

Physician Office/Draw Specimen Preparation

Maintain specimen refrigerated (2-8°C or 36-46°F) prior to transport.

Preparation for Courier Transport

Transport: 50 mL urine, refrigerated (2-8°C or 36-46°F). (Minimum: 30 mL)

Rejection Criteria

• Specimens not collected and processed as indicated.
• Urine Vacutainer^® tubes. Urine received in a glass or plastic tube with a rubber stopper may contain insufficient sample volume, preclude confirmatory testing, and give rise to contaminants and artifacts.

In-Lab Processing

Analyze urine specimen immediately upon receipt in the Laboratory.

Clinical Utility

Phencyclidine (PCP) is a drug of abuse. PCP acts as a stimulant, depressant, hallucinogenic and analgesic. It can be self-administered by smoking, nasal insufflation, intravenous injection or by oral ingestion. This assay is used to aid in the diagnosis and treatment of phencyclidine use or abuse. It provides a preliminary analytical result. Positive results are confirmed by chromatographic methods.
