目前国内外常用的产前诊断胎儿遗传性疾病的技术是羊水穿刺,其常见的并发症是流产和绒毛膜羊膜炎。有创产前诊断的并发症成为医疗纠纷的潜在因素。因此,无创产前诊断成为广大优生遗传学者们一直在积极探索的课题。经过几十年的大量的研究,利用孕妇外周血胎儿细胞或游离遗传物质诊断胎儿遗传性疾病成为目前比较有发展前景的无创产前诊断方法,其中,孕妇外周血胎儿有核
At present, the technology of prenatal diagnosis of fetal genetic diseases commonly used at home and abroad is amniocentesis, the common complication of which is abortion and chorioamnionitis. The complications of invasive prenatal diagnosis become potential causes of medical disputes. Therefore, non-invasive prenatal diagnosis has become the majority of eugenics scholars have been actively exploring the issue. After decades of large-scale research, the use of fetal blood cells in pregnant women or free genetic material in the diagnosis of fetal genetic disease is currently a more promising noninvasive prenatal diagnosis, including fetal blood in pregnant women with nuclear
