Taking the time to think through the ethical and practical questions these tests raise will not only prepare women for a conversation about testing but also for receiving whatever child they have been given.
Until recently, the only definitive way to identify Down syndrome or other trisomies (the presence of a third copy of a chromosome instead of the typical pair) came via amniocentesis or corionic villus sampling, called CVS. Both tests require invasive procedures and carry a small risk of miscarriage. Many women didn't choose these tests unless a second trimester screening indicated an elevated risk of a chromosomal condition. As a result, a diagnosis often came in the mid or late second trimester, making abortion both physically and legally more complicated than if discovered earlier.
