When examining traces of biological origin it is possible to draw conclusions from the findings of some urinary constituents in a stain produced by urine; via foetal urine, however, in the spots also amniotic fluid can be detected. By chromatographic analysis on a thin layer the authors are able to detect in spots from amniotic fluid urea without hippuric acid, in urine spots urea, creatinine and hippuric acid; in blood stains under equal conditions none of the above constituents is detected. The results, using the above method, can be considered a contribution which helps to differentiate these traces and it can be also used to detect amniotic fluid in stains.
在检查生物源痕迹时，可以从尿液产生的污渍中某些尿液成分的检测结果得出结论；然而，通过胎儿尿液，在这些斑点中也能检测到羊水。通过薄层色谱分析，作者能够在羊水斑点中检测到不含马尿酸的尿素，在尿液斑点中检测到尿素、肌酐和马尿酸；在相同条件下，血迹中未检测到上述任何成分。使用上述方法得到的结果可被视为有助于区分这些痕迹的一项贡献，并且它还可用于检测污渍中的羊水。
