摘　　要：犯罪分子的反侦查意识在不断增强,犯罪手段也不断翻新,对法庭科学领域的许多专业和研究方向提出了新挑战,对犯罪现场和物证所包含的潜在信息的挖掘、检测和研判提出了新要求。但是,作为常见物证的体液斑痕的分析,目前仍多侧重于形态学描述和DNA检验方面,而其中的隐藏信息其实还可以从理化分析角度做深入挖掘。本文从法医毒物分析角度对体液斑痕检验的研究进展进行总结,重点分析汗液、血液、唾液斑痕中药物毒品的检测,旨在为通过体液斑痕中特征成分刻画供体特征提供理论基础和参考依据。Criminals are always raising their anti-detection awareness and updating the offensive means, thereby posing many new challenges for forensic science to improve and enhance the capability of mining, monitoring and deciding the potential information embedded in the evidential materials and crime scenes. This paper focuses on the analysis of body fluids’ stains. Although the morphological depiction and DNA test are presently the major resorts to analyze body fluids’ stains, their hidden information can yet be further unearthed with the physicochemical methods. Through summarizing the research progress on toxicant drugs and their metabolins in the body fuids’ stains out of sweat, blood and saliva, the relevant toxicological discoveries are here provided along with the perspectives, aiming to supply a theoretical basis and reference for inferring donors’ features by body fuids’ specifc components.
