CONCLUSIONS: The extent to which free fetal DNA testing can be applied as a universal screening tool for trisomy 21, 18, and 13 depends mainly on assay accuracy and cost.
结论：胎儿游离dna检测作为21三体、18三体和13三体的通用筛查工具的程度，主要取决于测定方法的准确性和成本。
One of the ideas that I am working on is that if a patient has trisomy 7 only we can give them an epidermal growth factor receptor inhibitor for six months and see if we can eradicate those clones.
在这方面我正在研究的一种思路就是，如果一个患者只有7三体，我们可以用表皮生长因子受体阻滞剂治疗6个月，观察是否能根除这种克隆。
