Test Codes

Antrim #17079, EPIC: LAB7015, SOFT: PCP9

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.

STAT screen results available within 1 hour of receipt in the Laboratory, and confirmation within 12 hours.
Routine results available within 24 hours.

Reference Range

None Detected (Positive Cutoff: 50 ng/mL).

Test Methodology

Screen: Fluorescence Polarization Immunoassay (FPIA).
Confirmation: Gas Liquid Chromatography/Mass Spectrometer (GC/MS).

The confirmation component of this test was developed by Beaumont Health. It has not been cleared or approved by the FDA. The laboratory is regulated under CLIA as qualified to perform high-complexity testing. This test is used for clinical purposes and should not be regarded as investigational or for research.

Interpretation

Concentrations of drugs and/or metabolite(s) detected in urine have not been correlated to drug levels in the bloodstream or with the degree of impairment. The presence of a drug and/or metabolite(s) in urine is only an indication of previous drug exposure.

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.
