On the other hand, invasive prenatal testing, such as amniocentesis and chorionic villus sampling (CVS), involves collecting a sample of amniotic fluid or placental tissue to directly analyze the baby’s DNA These tests are usually performed between 15 and 20 weeks gestation and can provide more detailed genetic information, including the baby’s sex, paternity, and specific genetic disorders However, invasive prenatal testing carries a small risk of miscarriage, making it a less popular option for many expectant parents.
