title: [Use of RIA (radioimmunoassay) technics in the identification of narcotics in biological fluids].
abstract: Radioimmunoassay has been compared with extraction thin-layer chromatography and gas-chromatography for the detection of morphine and barbiturate in urine. Radioimmunoassay has been found to be the most sensitive and rapid method and its use in large scale screening and forensic toxicology is considered.
