Amniocentesis is typically performed between weeks 15 and 20 of pregnancy, with the 16th week being the most common time. This is because the amniotic fluid, which contains fetal cells for testing, is plentiful enough to provide an adequate sample, while the risk of complications is still relatively low. After 20 weeks, there is a higher risk of miscarriage and injury to the fetus.
