1、中国卫生检验杂志2014年11月第24卷第21期ChinJHealthLabTec,Nov2014,Vol24,No21·3119··临床检验·孕产妇产前红细胞血型不规则抗体检测的临床意义倪建萍,陈琪宁波市妇女儿童医院输血科,浙江宁波315010摘要:目的调查孕产妇红细胞血型不规则抗体的检出率及不规则抗体特异性的分布特点,预防母婴血型不合可能导致的新生儿溶血病的发生,并确保临床输血安全。方法收取本院2013年1月-2013年12月住院部产科所提供的4724例孕产妇血清,采用微柱凝胶法、试管间接抗人球蛋白法进行不规则抗体筛查与鉴定,免疫球蛋白类型用2
2、-巯基乙醇区分IgG及IgM,并对结果进行分析。结果4724例产妇中共检出不规则抗体28例,阳性率0.593%。其中6例为IgM抗体,20例为IgG类不规则抗体,2例为IgM、IgG混合抗体。在IgG不规则抗体中,抗-D6例,抗-E7例,抗-e2例,抗-Ec2例,抗-Ce1例,抗-Dc1例,抗-M1例。结论产前进行不规则抗体检测,对N-ABO-HDN早预防、早诊断、早治疗及避免紧急输血时的配血困难具有重要意义。关键词:血型不规则抗体;新生儿溶血病;溶血性输血反应;胎盘屏障中图分类号:R446.6文献标识码:A文章编号:1004-8685(2014)
