100%: Amniocentesis is 100% accurate.

Very accurate: An amniocentesis samples the fetal dna from amniotic fluid. Because the test is sampling the baby's dna directly the test is extremely accurate.

Personal decision: Both tests are 100% accurate in determining whether or not the baby has chromosomal problems like down's syndrome. Women over 40 have a 1 in 20 risk of this. Some people would terminate the pregnancy if they knew the baby had a chromosomal problem. The cvs gives you info earlier than the amnio but has a higher miscarriage rate.
A 42-year-old member asked:

Is a cvs a higher risk procedure than amniocentesis?

Dr. Erin Alward

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.
