Detection of phencyclidine in hair.

摘要: Phencyclidine (PCP) can be detected in human hair with commercially available radioimmunoassay reagents. Hair samples of all subjects admitting PCP use were positive, while thin-layer chromatographic urine analyses positive only one seven cases. Presumably the drug is incorporated into during periods and then retained that particular section for its lifetime. Earlier results this laboratory a more detailed study opiate retention indicated not nanogram levels could measured single strand hair, but also sectional analysis indicate time use. The again suggest sample serve as valuable tool determination abuse histories. accessibility stability long-term drugs exemplify potential advantages over body fluid sample.
