Order Phencyclidine (PCP) Screen and Confirmation, UrinePhencyclidine (PCP) testing in urine is a two-stage laboratory process: an initial immunoassay screen followed, when indicated, by a more specific confirmation method. The screen is designed to flag samples that may contain PCP, while the confirmation step identifies the compound with greater certainty and reduces the chance of a false positive from a structurally similar substance.
About Phencyclidine (PCP) Screen and Confirmation, Urine in Gresham
PCP testing usually begins with a screening immunoassay and may proceed to confirmation by a chromatographic method.
The screening immunoassay uses antibodies that bind to phencyclidine or closely related structures. It provides a rapid qualitative result, typically reported as negative or as requiring further testing. Because immunoassays can cross-react with other compounds, a reactive screen is not by itself a definitive identification.
Confirmation is performed with a more selective technique, most often gas chromatography-mass spectrometry or liquid chromatography-tandem mass spectrometry. These methods separate the components of the sample and detect PCP by its mass spectrum, which allows the laboratory to identify the drug itself rather than a related structure.
Urine is the specimen of choice for routine PCP testing because phencyclidine and its metabolites are excreted in urine over a detectable window after use. Detection times vary with dose, frequency of use, individual metabolism, and the sensitivity of the assay, so a negative result does not necessarily exclude earlier exposure.
