The case comes on the heels of a scientific discovery last December, when two research teams independently reported that they could reconstruct fetal DNA taken from the mother’s blood. Analyzing this DNA would allow testing for a range of genetic conditions, including one of the most common chromosomal disorders, Down syndrome, earlier in pregnancy than ever before. Additionally, the simple blood draw would evade the risk of miscarriage that comes with current methods of prenatal screening, including amniocentesis (which involves sticking a needle through the abdomen and into the uterus) and chorionic villus sampling (done either by a needle through the abdomen or by prodding a tube through the vagina and cervix).
