阅读说明：本技术 筛查系统和方法 (Screening system and method ) 是由 尼古拉斯·伦奇 马特·赫里斯 约翰·麦戈尼格尔 艾伦·马丁 苏珊娜·德鲁里 于 2018-07-18 设计创作，主要内容包括：描述了产前筛查系统,其包括湿性实验室装置和数据处理装置,所述数据处理装置可操作地与所述湿性实验室装置交换指令和数据。所述数据处理装置包括数据库装置,在所述数据库装置中存储有在所述数据处理装置上可执行的一种或多种算法可访问的遗传信息,其中所述湿性实验室装置可操作地从妊娠母亲收集一个或多个母体血液样品。此外,所述湿性实验室装置可操作地分离存在于来源于一个或多个母体血液样品的血浆的无细胞DNA(cfDNA)中的游离胎儿DNA(ffDNA)片段,其中所述分离采用基于无细胞胎儿DNA(cffDNA)片段特异性终点坐标的引诱物,并且所述数据处理装置可操作地分析所分离的游离胎儿DNA(ffDNA)并与存储在所述数据处理装置中的一种或多种DNA模板进行比较以确定一个或多个母体血液样品中存在的胎儿DNA的一种或多种生物学特征的出现。(A prenatal screening system is described that includes a wet laboratory device and a data processing device operable to exchange instructions and data with the wet laboratory device. The data processing device includes a database device having stored therein genetic information accessible by one or more algorithms executable on the data processing device, wherein the wet laboratory device is operable to collect one or more maternal blood samples from a pregnant mother. Further, the wet laboratory device is operable to isolate free fetal DNA (ffdna) fragments present in cell-free DNA (cfdna) of plasma derived from one or more maternal blood samples, wherein the isolation employs an attractant based on cell-free fetal DNA (cffdna) fragment-specific endpoint coordinates, and the data processing device is operable to analyze the isolated free fetal DNA (ffdna) and compare it to one or more DNA templates stored in the data processing device to determine the presence of one or more biological characteristics of fetal DNA present in one or more maternal blood samples.)
