摘要 目的探讨早中孕整合筛查对提高胎儿染色体异常及神经管缺陷筛查效率的意义。方法分析15 599例早中孕整合筛查的筛查结果和妊娠结局,比较早孕期、中孕期高危组和低危组预产年龄、采血孕周、采血体质量、各单项指标中位数倍数(MOM)。结果早中孕整合筛查假阳性率183/15 599(1.17%),阳性预测值3.68%(1/27),检出率100%。预产年龄、胎儿颈部透明层(NT)、妊娠相关血浆蛋白-A(PAPP-A)、甲胎蛋白(AFP)、游离雌三醇(u E3)、早孕期及中孕期HCG单项MOM值提示唐氏综合征(DS)高危、低危差异均有统计学意义(均<0.05),AFP、中孕期HCG单项MOM值提示开放性神经管缺陷(NTD)高危、低危差异均有统计学意义(均<0.05)。结论早中孕整合筛查假阳性率低,有利于减少有创性产前诊断负担,易于为大于35周岁的高龄孕妇接受。
