The PCP (phencyclidine) drug test checks for the presence of phencyclidine, a dissociative drug also known as angel dust, in a blood sample. It is typically ordered when a person shows signs of acute intoxication, such as agitation, confusion, or hallucinations, or as part of a broader drug screening in emergency or clinical settings.
What it measures
- Phencyclidine (PCP) — The parent drug; its presence in blood indicates recent use.
- PCP metabolites — Breakdown products of PCP that the body forms; these can also be detected.
- Qualitative detection — Most blood tests simply report whether PCP is present above a set cutoff.
- Quantitative level (if performed) — Some tests measure the exact amount of PCP in the blood, which may help assess severity.
Who it is for
Emergency room doctors, toxicologists, or other clinicians may order this test when someone has sudden mental status changes, unusual behavior, or suspected drug exposure. It is not a routine screening test for most people.
Preparation
No special preparation, such as fasting, is needed for a PCP blood test. Tell your healthcare provider about any medications or substances you have taken, as they can affect test results.
Results and what they mean
