Amniocentesis is an invasive test that involves extracting fluid from the sac around the fetus using a long, thin needle. It’s not any more pleasant than it sounds, but may be necessary if your partner’s ultrasounds or blood panels indicate an increased likelihood of birth defects like Down Syndrome. Amniocentesis is 99.4-percent accurate in assessing these defects; but the procedure carries a very small risk of miscarriage, which is why it’s avoided unless previous screenings for similar issues are positive.
