Phencyclidine, also known as PCP, is a hallucinogen that was first marketed as a surgical anesthetic in the 1950s. It was removed from the market because patients receiving it became delirious and experienced hallucinations. The PCP One Step Phencyclidine Test Strip (Urine) is a lateral flow chromatographic immunoassay for the detection of Phencyclidine in urine at a cut-off concentration of 25 ng/mL. This rapid test is intended for professional in vitro diagnostic use only and comes in bulk OEM.
