title: Is urine a suitable material for the preliminary screening of drugs in autopsy cases?
abstract: This paper reports a survey of drug screening in the urine specimens of 45 autopsy cases whose livers contained medicinal substances. The extractions were carried out by a solid phase/liquid technique and the analyses by thin-layer chromatography. Nine compounds out of 43 actually present in the liver were not detectable in the urine; eight cases with high drug concentrations in the liver and also in the blood would have evaded the intoxication suspicion had the urine been used as the only material for the chemical survey. On the basis of these data we advocate that the preliminary drug screening of medical-examiner cases not be carried out on urine alone.
