摘要: A method for preserving and processing fetal nucleic acids located within maternal plasma is disclosed, wherein a sample of blood containing treated to reduce both cell lysis the cells deoxyribonuclease (DNase) ribonuclease (RNase) activity acids. The treatment aids in increasing amount that can be identified tested while maintaining structure integrity
