Abstract:Method for the collection of blood, urine, bile and alcohol washes of face and fingers from fatally injured drivershave been developed. Specimens have been collected ffom Alcohol Safety ALtion Project areas and other cooperating areas. The samples were supplied by'coroners and medical examiners from fatally injured drivers who were dead on arrival at the hospitals. Nine hundred and twenty-nine specimen collection kits were distributed to 44 different areas. One hundred and ninety-one kits were returned with specimens from 18 areas. Methods for analysis of blood, urine and bile for 44 commonly abused drugs were developed. These methods consisted of extraction of the fluids, followed by a qualitative thin-layer chromatographic screen. If the screen indicated positives, quantitative confirmation was conducted. Mass spectrometry was also conducted if additional qualitative information was necessary. Alcohol washes of face and fingers were examined for evidence of marihuana using a thin-layer chromatographic method. Blood samples were assayed for alcohol content using a gas chromatographic method. The analytical results indicated that 51% of the drivers had ingested alcohol and 33% of the drivers were legally drunk (alcohol content of blood >= 0.15%). Twenty-four percent of the specimens examined evidenced the presence of drugs other than alcohol: 11% evidenced drugs and no alcohol; 13% evidenced drugs and alcohol. /Abstract from report summary page/
