在法医学检验中,血痕种属鉴别是一个重要的检验项目,传统方法是用环状沉淀反应、琼脂扩散试验等。前者由于检材用量大,并常因抗原、抗体比例不适而出现假阴性反应,后者也存在灵敏度低,反应时间长等缺点。我们用抗球蛋白抑制试验对人及不同种属的动物血痕作了种属鉴定方面的研究。 In forensic tests, identification of bloodstain species is an important test items, the traditional method is to use ring precipitation reaction, agar diffusion test. The former due to large amount of samples, and often due to antigen, antibody false reaction appeared false-negative reaction, which also has low sensitivity, long reaction time and other shortcomings. We used the anti-globulin inhibition test to study the species identification of human and animal bloodstains of different species.
