一些妇女在15孕周后行羊膜穿刺术因妊娠期太晚而不能接受,<15孕周羊水内胎甲蛋白(AF-AFP)对检出开放性神经管缺损(NTD)的敏感性不清且缺乏乙酰胆硷酯酶(AchF)的资料。本文报道了在15孕周以前经AF-AFP测定和AchE凝胶电泳检出开放性NTD的经验并对早期AF标本常规AchE检查结果进行评价。
Some women are unacceptable for amniocentesis after 15 weeks of gestation due to late gestational age. <15 weeks of gestation AF-AFP is not sensitive and has no evidence of susceptibility to open NTD Cholinesterase (AchF) information. This article reports on the experience of detecting open NTD by AF-AFP and AchE gel electrophoresis before the 15th week of gestation and reviews the results of conventional AchE in early AF.
