研究目的:

本研究拟在前期成功建立的无创产前巴氏水肿胎检测方法基础上扩大检测范围,探索应用于巴氏水肿胎、染色体非整倍体(T21/T18/T13)以及 6 种基因组大于 3Mb 病检测,评估该技术临床应用可行性。  

Objectives of Study:

This study is built upon the non-invasive prenatal testing method for Bart's hydrops fetalis previously established by our research group. The objective is to expand the detection scope of this method to include Bart's hydrops fetalis, chromosomal aneuploidies (Trisomy 21, Trisomy 18, Trisomy 13), and six types of genomic disorders characterized by aberrations larger than 3 Mb. The clinical feasibility of this expanded application will be evaluated.
