Drug Screen PCP

One-Step Phencyclidine Test


The Drug Screen PCP is a lateral flow, one-step immunoassay for the qualitative detection of phencyclidine in human urine at a cut-off of 25 ng/ml. This product is used to obtain a visual, qualitative result and is intended for use by drug testing professionals in drug testing programs. The assay should not be used without proper supervision and is not intended for over the counter sale to lay persons.

This assay provides only a preliminary analytical test result. A more specific alternative chemical method must be used in order to obtain a confirmed analytical result. Gas chromatography/mass spectrometry (GC/MS) has been established as the preferred confirmatory method by the National Institute on Drug Abuse (NIDA). Clinical consideration and professional judgment should be applied to any drug of abuse test result, particularly when preliminary positive results are indicated.


Phencyclidine is an arylcyclohexylamine that was originally used as an anesthetic agent and a veterinary tranquilizer. Phencyclidine can produce hallucinations, lethargy, disorientation, loss of coordination, trance-like ecstatic states, a sense of euphoria and visual distortions. It has many street names, such as “angel dust” and “crystal cyclone”, etc. phencyclidine can be administered orally, by nasal ingestion, smoking, or intravenous injection. It is metabolized in the liver and excreted through the kidneys. The half-life of phencyclidine in the body is around three days. Suction and urinary acidification in the treatment of overdose typically reduces its half-life from three days to one day.

Urine based screening tests for drugs of abuse range from simple immunoassay tests to complex analytical procedures. The speed and sensitivity of immunoassays have made them the most widely accepted method for screening urine for drugs of abuse. The Drug Screen PCP is based on the principle of the highly specific immunochemical reactions of antigens and antibodies which are used for the analysis of specific compounds in biological fluids. This test is a rapid, visual, competitive immunoassay that can be used for the qualitative detection of phencyclidine in human urine at a 25 ng/ml cut-off concentration.


The Drug Screen PCP is a one-step immunoassay in which a chemically labeled drug (drug conjugate) competes with the drug which may be present in urine for limited antibody binding sites. The test device contains a membrane strip which was pre-coated with drug conjugate on the test band region. A colored anti-phencyclidine monoclonal antibody-colloidal gold conjugate pad is placed at the end of the membrane. The colored antibody-colloidal gold conjugate moves along with urine, chromatographically by the capillary action, across the membrane, in the absence of drug in the urine, the colored antibody colloidal gold conjugate attaches to the drug conjugate on the test band region to form a visible line as the antibody/drug conjugate complexes. Therefore, the formation of a visible precipitant in the test band region occurs when the test urine is negative for the drug. When the drug is present in the urine, the drug/metabolite antigen competes with the drug conjugate on the test band region for the limited antibody sites. When a sufficient amount of drug is present, it will fill the limited antibody  binding sites. This will prevent attachment of the colored antibody-colloidal gold conjugate to the drug conjugate zone on the test band region. Therefore, absence of the color band on the test region indicates a positive result. A control or reference band with a different antigen/antibody reaction is also added to the immunochromatographic membrane strip to indicate that the test is performed properly. This control line should always appear regardless of the presence of drug or metabolite. This means that negative urine will produce two colored bands, and positive urine will produce only one band. The presence of this colored band in the control region also serves as verification that 1) sufficient volume has been added, and 2) that proper flow was obtained.

The test kit should be stored refrigerated or at room temperature (2-30℃). Each device should remain in its sealed pouch for the duration of the shelf-life.



·  For professional use only.

· Urine specimens may be potentially infectious. Proper handing and disposal methods should be established.

·  Avoid cross-contamination of urine samples by using a new specimen collection container and specimen pipette for each urine sample.


The Drug Screen PCP is formulated for use with urine specimens. Fresh urine does not require any special handing or pretreatment. Urine samples should be collected such that testing can be performed as soon as possible after the specimen collection, preferably during the same day. The specimen may be refrigerated at 2-8℃ for 2 days or frozen at -20℃ for a longer period of time. Specimens that have been refrigerated must be equilibrated to room temperature prior to testing. Specimens previously frozen must be thawed, equilibrated to room temperature, and mixed thoroughly prior to testing.

Note: Urine specimens and all materials coming in contact with them should be handled and disposed of as if capable of transmitting infection. Avoid contact with skin by wearing gloves and proper laboratory attire.


Review “Specimen collection” instructions. Test strips, patient’s samples, and controls should be brought to room temperature (20-30℃) prior to testing. Do not open pouches until ready to perform the assay.

Remove the test strip from its protective pouch (bring the test to room temperature before opening the pouch to avoid condensation of moisture on the membrane), and label the strip with patient or control number.

·      Immerse the test strip in the urine sample with the arrow end pointing toward the urine. Do not immerse the strip above the printed MAX line. After a minimum of 15 seconds, remove the test strip from the urine and lay fiat on a non-absorptive clean surface. Alternatively, the test strip may be left in the test sample, as long as the strip is not immersed above the MAX line. A separate test strip must be for each sample or control.

·      Read result between 3 to 8 minutes after the addition of samples. Do not read result after 8 minutes.



Two pink-rose lines (bands) are visible in the control ("C") and test ("T") areas of the test window. The intensity of the test line may be less than that of the control line; this still means negative result.


The control line appears in the test window, but the test line is not visible.


The test is invalid if the control line is not visible at five minutes. The test failed, or the test procedure was not followed properly. Verify the test procedure and repeat the test with a new testing strip.

Note: A very faint line on the test region indicates that the phencyclidine in the sample is near the cut-off level for the test. These samples should be re-tested or confirmed with a more specific method before a positive determination is made.


1.         The assay is designed for use with human urine only.

2.       A positive result with any of the tests indicates the presence of a drug/metabolite only and does not indicate or measure intoxication.

3.         There is a possibility that technical or procedural errors as well other substances or factors not listed may interfere with the test and cause false results. See SPECIFICITY for lists of substances that will produce positive results, or that do not interfere with test performance.

4.         If it is suspected that the samples have been mislabeled or tampered with, a new specimen should be collected and the test should be repeated.


Good laboratory practice recommends the use of control materials to ensure proper kit performance. Quality control specimens are available from commercial sources. When testing the positive and negative controls, use the same assay procedure as with a urine specimen.


A.      Accuracy

The accuracy of Drug Screen PCP was evaluated in comparison to a commercially available immunoassay at a cut-off of 25 ng/ml for phencyclidine. One hundred twenty two (122) urine samples, collected from presumed non-user volunteers, have been tested by both procedures with 100% agreement.

In a separate study, fifty (50) urine samples, obtained from a clinical laboratory where they were screened and confirmed as positives by the commercially available immunoassay and GC/MS, were tested with the Drug Screen PCP. Of the 50 samples with phencyclidine concentration from 34.6 ng/ml to 1846 ng/ml, all were found positive by both methods (100% agreement).

B.      Reproducibility

The reproducibility of the Drug Screen PCP was evaluated at four different sites using blind controls. Of the 60 samples without phencyclidine all were determined negative. Of the (60) samples with phencyclidine concentration of 50 ng/ml, all were determined positive.

C.      Precision

The precision of the Drug Screen PCP was determined by conducting the test with spiked controls. The control at the 50 ng/ml should give a positive result.
