title: Measurement of the amino acid metabolite of phencyclidine by selected ion monitoring.
abstract: A technique is described for the extraction and quantitation of the pentanoic acid metabolite of phencyclidine by gas chromatography/mass spectrometry. This compound was measured in urine samples from asymptomatic pregnant patients who used phencyclidine (PCP) and their neonates. The technique is sensitive to 25 ng ml-1 urine and standard curves were linear at 25-2000 ng ml-1. Levels in samples from asymptomatic patients were 27-1388 ng ml-1. Results suggest that the pentanoic acid metabolite could be considered as a screening marker for occasional PCP use.
