No: Amniocentesis is usually offered between 15-20 weeks, with a pregnancy loss rate of about 1 in 300-500. Chorionic villus sampling (cvs) is offered after 9 weeks. The pregnancy loss rate appears to be about the same as amniocentesis. There are additional fetal risks if it is performed before 7 weeks. The benefit of cvs is earlier detection, which allows for safer termination, if desired.

Yes, if: Depending on when the amnio is done; if done at 16-18 weeks, the amnio risk is somewhat lower (around 1/200.).

Are there any risks to the amniocentesis procedure?

Yes.: As with any procedure, there are risks. Possible complications include direct or indirect fetal injury, rupture of membranes, infection, & miscarriage. Maternal injury and direct injury to the fetus are especially rare. Timing also affects risk-- amniocentesis done before 15 weeks carries a higher risk of complications. Second trimester amniocentesis carries the lowest risk of fetal loss.
