Is genetic testing of prenatal babies harmful to the health of the babies and/or the mothers?
On One Hand: Genetic Testing Poses RisksPrenatal genetic testing of a developing fetus is done on fetal cells taken through amniocentesis, a sampling of amniotic fluid, or chorionic villus sampling, when cells are taken from the placenta. According to Medline Plus, risks of these procedures include fetal injury or infection, miscarriage, leaking amniotic fluid, bleeding from the vagina, Rh sensitization and broken membranes.On the Other: Complications Are UncommonMost of the risks associated with amniocentesis and chorionic villus sampling are rare. Miscarriage, a serious risk, is one of the more common complications of both procedures. The Mayo Clinic reports that there is a one in 300 to 500 risk of miscarriage for amniocentesis and a one in 100 risk of miscarriage for chorionic villus sampling.Bottom LinePrenatal genetic testing can pose risks to the health of both the mother and the baby.
