| Abstract: The discovery of circulating cell-free fetal DNA has fundamentally transformed the landscape of prenatal testing and rapidly found its way into global clinical applications. Inspired by the promising development of the use of cell-free DNA， fetal cell-free RNA in maternal plasma of pregnant women has been increasingly studied. In this review， we focus on discussing the properties of plasma RNA and its potential applications. |
