Phencyclidine (PCP) Screen and Confirmation in Illinois

The PCP screen and confirmation test detects phencyclidine (PCP), a dissociative drug, in the blood. It is ordered when someone shows signs of intoxication or psychosis, or as part of a drug testing panel for medical or legal reasons. A positive screen is typically confirmed with a more specific method to avoid false results.

What it measures

PCP screen — An initial test that checks if PCP may be present. It gives a quick yes/no or numeric result.
PCP confirmation — A follow-up test that identifies PCP more precisely, reducing false positives.
PCP level (quantitative) — Sometimes measured to estimate how much PCP is in the blood, but levels do not always match symptoms.

Who it is for

A doctor or other healthcare provider may order this test for someone with unexplained agitation, hallucinations, or abnormal movements. It can also be ordered by employers or legal authorities as part of a required drug test.

Preparation

No fasting or special preparation is needed for a blood PCP test. Tell your provider about any medications or substances you take, as some may affect the test.

Results and what they mean

Results are reported as positive (PCP detected) or negative (not detected), often with a concentration. A positive screen is usually confirmed before being considered final. Only a qualified clinician can interpret these results in the context of your health; this information is not medical advice.
