This is an editorial piece that was published on
Nature. Large strides are being made in the capabilities of non-invasive prenatal testing. Previously, tests such as
amniocentesis and
chorionic villi sampling were used to help determine if there were any genetic abnormalities present in the fetus. Both of these testing techniques come with small risks of possible miscarriage. Now, through blood work, testing is able to be done by sampling snippets of fetal DNA that is found within the mother's blood. These tests can help find chromosomal abnormalities such as Trisomy-21 (Down Syndrome).
Many parents would like to know if their unborn baby has any abnormalities. As mothers get older their risk for having babies with such abnormalities is increased. Amniocentesis have been one of the few methods in diagnosing such abnormalities but with potential risk to the unborn baby. Diagnosis through blood work of the mother is ideal as it poses no risk to the baby and still allows parents the ability to diagnose genetic disorders.
I think that this is a good idea and a great way to detect abnormalities. Many women want to know and be able to control their pregnancies and with a simple blood work, they are able to have more control and knowledge about their children and what they should do.
