    摘要: A prenatal screening system includes a wet-laboratory arrangement and a data processing arrangement to exchange instructions and data with the wet-laboratory arrangement. The data processing arrangement includes a database arrangement storing genetic information accessible to one or more algorithms executable on the data processing arrangement. The wet-laboratory arrangement collects one or more maternal blood samples from a pregnant mother. The wet-laboratory arrangement isolates free fetal DNA fragments present in cell-free DNA derived from plasma of the one or more maternal blood samples. The isolation utilizes baits based upon coordinates of cell-free fetal DNA fragment specific end-points, and the data processing arrangement analyses the isolated free fetal DNA and compares with one or more DNA templates stored in the data processing arrangement for determining an occurrence of one or more biological characteristics of fetal DNA present in the one or more maternal blood samples.
