Morphine in blood and urine spots was detected by the radioimmunoassay (125-J-Abuscreen R, Hoffmann La Roche) in nanogram quantities. Blood and urine drops containing morphine (5 or 20ng) were dropped on wood, fired clay or cotton and stored for perios of 1 to 21 days in a dry or humid environment. Detection in blood stains on cotton was achieved in all cases. Results were more variable in blood spots on clay or wood, but in most cases detection was possible. In urine, morphine was detectable only on cotton. The differences are explained by different degrees of adsorption of blood and urine on the materials and the difficulties of elution thereof.
采用放射免疫分析法（125-J-Abuscreen R，霍夫曼·罗氏公司）检测血液和尿液斑点中的纳克级吗啡含量。将含有吗啡（5或20纳克）的血滴和尿滴滴在木材、烧制的黏土或棉花上，并在干燥或潮湿环境中保存1至21天。在所有情况下均能检测到棉花上的血迹中的吗啡。黏土或木材上血斑的检测结果变化更大，但在大多数情况下都可以检测到。在尿液中，仅在棉花上可检测到吗啡。这些差异是由于血液和尿液在材料上的吸附程度不同以及洗脱的困难所致。
