妇外周血中胎儿细胞的发现和分子生物学技术的进步 ,为无创伤性产前诊断技术的发展开辟了新途径。这一技术与传统的产前细胞学检查相比 ,对母亲和胎儿更安全可靠且更易为孕妇所接受。本文就无创伤性产前诊断技术的方法、最新技术、存在的困难及其发展前景做一简要介绍
The discovery of fetal cells in women’s peripheral blood and advances in molecular biology technology have opened up new avenues for the development of noninvasive prenatal diagnostic techniques. This technique is safer and more reliable for mothers and fetuses than maternal prenatal cytology and more accessible to pregnant women. This article gives a brief introduction of the method, the latest technology, the existing difficulties and the prospects of development of noninvasive prenatal diagnosis
