Abstract:
A reliable and sensitive method to analyze fentanyl in urine was developed using radioimmunoassay (RIA). Fentanyl, a highly lipophilic drug (pKa 7.7), has become a common drug of abuse. We evaluated three analytical techniques to detect fentanyl in urine. This paper reports the best of the three - a modified solvent extraction combined with a fentanyl RIA.
