摘要 目的探讨115例汉族献血者ABH分泌型与非分泌型血清学分布及基因多态性。方法用凝集抑制试验检测115例标本ABH血型物质,聚合酶链反应-序列特异性引物(PCR-SSP)对选取标本作ABH基因定型,直接测序技术对46例血清学检测为分泌型标本进行分析。结果 115例献血者中分泌型95例,非分泌型20例;分泌型献血者A物质效价均高于B物质效价和H物质效价(P<0.05);115例献血者中,无A385T基因突变的48例均为分泌型;A385T基因突变者中,杂合子基因385A/385T 39例,为分泌型,纯合子385T/385T基因28例,8例为分泌型,20例为非分泌型;1例分泌型标本出现178C/T新的突变位点。结论 ABH血型A物质效价高于B、H物质,115例汉族人群中存在不同于高加索人群及非洲人群的A385T基因突变。
