法医学血痕种属检验的方法很多，如环状沉淀试验，琼脂糖单扩散试验以及对流免疫电泳试验等。这些方法操作简便，但灵敏度低，易受血痕所附着的客体以及化学合成物等因素的干扰。笔者参照文献［1］介绍的方法，用酶标抗人Hb单克隆抗体检测微量血痕种属，取得良好的效果，现报道 Forensic bloodstain species test many ways, such as ring precipitation test, agarose single diffusion test and convection immune electrophoresis test. These methods are simple and easy to use, but less sensitive, susceptible to blood clots attached to objects and chemical compounds and other factors. The author refers to the method described in the literature [1], with the enzyme-labeled anti-human Hb monoclonal antibody detection of trace blood group species, and achieved good results, are reported
