What is PCP on a drug test? PCP stands for phencyclidine, a dissociative drug that may be included as a dedicated panel on urine drug screening devices. When PCP appears on a drug test, the device is designed to provide a preliminary qualitative result for PCP at the cutoff established by the manufacturer.
A rapid PCP drug test does not measure the exact concentration of PCP, determine impairment, establish when exposure occurred, or replace laboratory confirmation. It indicates whether the screening response is below or at or above the applicable cutoff.
Organizations requiring a multi-panel urine test that includes PCP can review the 12 panel PCP drug test kit. This CLIA-waived Serenity cup contains a dedicated PCP assay at a 25 ng/mL cutoff together with 11 additional urine screening panels.
PCP Drug Test Meaning and Purpose
PCP is the abbreviation for phencyclidine. It is also commonly known as angel dust. The National Library of Medicine describes PCP as an illegal street drug that may be used in several different forms.
In drug testing, PCP refers to the assay used to screen a specimen for phencyclidine. PCP is frequently included in multi-panel drug testing configurations, but it is not automatically included in every urine test or every 12-panel cup.
A PCP screening result must be interpreted within the limitations of the selected device. A preliminary non-negative result does not by itself establish misuse, impairment, dose, route of administration, or the exact time of exposure.
How Does a PCP Drug Test Work?
PCP urine screening
A rapid PCP urine test commonly uses a competitive immunoassay. After the specimen is collected and the test is activated according to the manufacturer’s instructions, colored lines develop in the Control and Test regions.
The Serenity 12 panel PCP cup uses a PCP screening cutoff of 25 ng/mL. The cutoff is the concentration at which the screening device changes its reported result. It should not be interpreted as an impairment level or a fixed detection period.
Cutoffs may differ between screening products and laboratory methods. Always verify the current package insert supplied with the exact device. Additional information is available in our drug test cutoff level guide.
How to read PCP drug test results
| Screening result | Line pattern | Meaning |
|---|---|---|
| Negative | Control line and Test line appear | PCP was not detected at or above the applicable screening cutoff |
| Preliminary non-negative | Control line appears but the Test line does not appear | The screening result requires handling according to the testing program and confirmation when applicable |
| Invalid | Control line does not appear | The result should not be reported and testing should be repeated with a new device |
For the PCP cup described on this page, a visible Test line together with a valid Control line is interpreted as negative even when the Test line is faint. Line darkness should not be used to estimate how much PCP may be present.
Users should read every panel separately and follow the interpretation time stated in the product instructions. See our complete guide explaining how to read a drug test cup.
Basic testing procedure
- Confirm that the package is sealed and the device has not expired.
- Review the current manufacturer’s instructions before collecting the specimen.
- Collect urine directly into the test cup according to the required collection volume.
- Replace and secure the lid immediately after collection.
- Review the built-in temperature strip within the specified time.
- Place the cup on a flat surface and allow the test panels to develop.
- Read the PCP panel and the remaining assays within the valid interpretation window.
- Arrange appropriate laboratory confirmation for a preliminary non-negative result when required.
Is PCP Included in a 12 Panel Drug Test?
PCP may be included in a 12 panel drug test, but there is no universal configuration shared by every 12-panel cup. The panel number describes the number of included drug or drug-metabolite assays, not one mandatory list of substances.
Some 12-panel configurations include PCP, while others replace PCP with TCA, EtG, fentanyl, K2, or another specialty panel. Buyers should review the complete analyte list instead of relying only on the panel count or product name.
The Serenity PCP configuration includes:
| Drug or drug class | Abbreviation | Screening cutoff |
|---|---|---|
| Amphetamines | AMP | 1,000 ng/mL |
| Barbiturates | BAR | 300 ng/mL |
| Buprenorphine | BUP | 10 ng/mL |
| Benzodiazepines | BZO | 300 ng/mL |
| Cocaine metabolite | COC | 300 ng/mL |
| Ecstasy | MDMA | 500 ng/mL |
| Methamphetamine | MET | 1,000 ng/mL |
| Methadone | MTD | 300 ng/mL |
| Opiates/Morphine | OPI | 300 ng/mL |
| Oxycodone | OXY | 100 ng/mL |
| Phencyclidine | PCP | 25 ng/mL |
| Marijuana metabolite | THC | 50 ng/mL |

PCP Detection Windows and Test Limitations
There is no single PCP detection window that applies to every person and every testing method. Detection may vary according to the amount and frequency of exposure, individual metabolism, specimen timing, urine concentration, testing method, and assay cutoff.
Laboratory confirmation methods and rapid immunoassay cups may use different analytical thresholds. A detection estimate associated with one laboratory method should not automatically be applied to every rapid PCP drug test.
A PCP/25 cutoff is not a promise that PCP will remain detectable for a specific number of hours or days. The cutoff only describes the concentration used by the screening assay to distinguish its reported results.
Additional general information is available in our drug detection times guide.
A rapid PCP urine screen cannot determine:
- The exact concentration of PCP in the specimen
- The amount or dose associated with the screening response
- Whether the donor is impaired
- The exact time of exposure
- The route by which PCP may have been used
Can a PCP Drug Test Produce a False-Positive Result?
An unexpected PCP screening result may occur because immunoassays can react with certain structurally similar compounds. Cross-reactivity varies between products, manufacturers, assays, and tested concentrations.
Users should review the cross-reactivity and limitations sections of the package insert supplied with the exact test. Information associated with one PCP assay should not automatically be applied to a different device.
A preliminary non-negative result should not be treated as definitive proof of PCP exposure. When required by the testing program, policy, or applicable regulations, the specimen should be confirmed using an appropriate laboratory method.
The testing organization should also have procedures for documenting reported medications, reviewing unexpected results, maintaining specimen integrity, and recording confirmation outcomes.
