摘要 目的探究血清妊娠相关血浆蛋白-A(PAPP-A)、游离β-人绒毛膜促性腺激素(Fβ-h CG)水平在孕早期胎儿染色体非整倍体异常筛查中的应用价值。方法选取三门峡市中心医院3 200例孕早期妇女,均行血清PAPP-A、Fβ-h CG水平检测,以妊娠或引产为金标准,统计对比妊娠或引产结果、PAPP-A和Fβ-h CG水平,并对比其诊断准确度、特异度、灵敏度。结果染色体非整倍体异常15例,其中45X异常2例,13-三体异常2例,18-三体异常3例,21-三体异常8例;染色体非整倍体异常组血清PAPP-A水平低于染色体正常组,血清Fβ-h CG水平高于染色体正常组,两者联合诊断准确度、特异度、敏感度均高于PAPP-A、Fβ-h CG单独检测,差异有统计学意义(P<0.05)。结论血清PAPP-A、Fβ-h CG水平联合检测可提高孕早期胎儿染色体非整倍体异常诊断准确度、特异度及敏感度。
