本文介绍了利用型特异性沉淀素血清环状沉淀法检验人唾液斑、精液斑ABO血型的方法与实验结果,并与中和试验及解离试验进行了比较。实验结果表明,本法操作简便,对多种干扰条件下的唾液斑、精斑均具有高度的型特异性,并能从分泌液与血液的混合斑中准确地鉴别出分泌液的血型。本法仅需0.4cm的分泌斑纱线即可进行血型鉴定,其灵敏度高于中和试验而略低于热解离试验,并能有效地检出陈旧分泌液斑中的型物质,因此适于在实际检案中应用。
In this paper, the methods and results of ABO blood type test of human saliva plaque and semen plaque with circular precipitation of type specific precipitin were introduced, and compared with neutralization test and dissociation test. The experimental results show that the method is simple and easy to operate, highly specific to saliva spots and fine spots under various interference conditions, and can accurately identify the blood type of the secretions from the mixed spots of the secretion and the blood. This method requires only 0.4cm of the secretion of spot yarn can be blood type identification, the sensitivity is higher than the neutralization test and slightly lower than the thermal dissociation test, and can effectively detect the type of substances in old secretions, so In the actual application of the prosecution.
