摘　　要：血迹是凶杀、伤害等案件中最常见和最重要的一种物证。血痕预试验是利用化学检测的方法从现场大量可疑的斑迹中初步筛选出可能是血的痕迹物证。本文对常用血痕预试验试剂的应用现状及其灵敏度、特异性、稳定性等进行分析比较,同时对预试验检测中存在的问题及今后的发展趋势进行综述,旨在为更好地研究、利用血痕预试验试剂提供参考。Bloodstain is the most common and perhaps the most important physical evidence in the practice of criminal justice today. A presumptive test can be used in detecting dilute or invisible blood in crime scenes. In this paper, the author analyzed the application, specificity, sensitivity, safety and stability of the common presumptive test reagents. Problems in the presumptive tests and its future trend were also discussed, so as to provide reference for the related research and application.
