Detection of Phenobarbital in Bloodstains, Semen, Seminal Stains, Saliva, Saliva Stains, Perspiration Stains, and Hair

Abstract Low nanogram quantities of phenobarbital were detected in a 10-μL dried blood stain and in other physiological fluids by using radioimmunoassay. The age of the stain versus detectability of phenobarbital and the cross-reactivity of vaginal secretions were investigated.
