title: Determination of cross-reactant drugs with a new morphine radioimmunoassay procedure.
abstract: A study to determine the specificity of a new morphine radioimmunoassay (RIA) procedure was performed on 23 drugs of forensic science interest. Spiked whole blood and urine specimens were analyzed and the apparent morphine concentrations determined. All compounds analyzed showed low cross-reactivity, indicating a high specificity for morphine.
