Chorionic villus sampling can be done in the first trimester of pregnancy, typically between weeks 10-13, which is earlier than amniocentesis, which is typically performed between weeks 15-20. This earlier timing can be beneficial for certain situations where earlier diagnosis is desired, such as in cases where the mother is at increased risk for genetic disorders or when fetal anomalies have been detected through ultrasound. However, it should be noted that while chorionic villus sampling has a lower risk of fetal loss compared to older methods of prenatal diagnosis, it still carries some risk and should be weighed carefully against the potential benefits.
