What is amniocentesis?
Amniocentesis is a prenatal test in which a doctor, guided by ultrasound, passes a needle through your abdomen and into the amniotic sac. A small amount of amniotic fluid is withdrawn and analyzed to screen for fetal defects and certain genetic abnormalities such as Down syndrome. Results of the testing are generally available in two to three weeks.

Who should get an amniocentesis?
There are a variety of reasons why a doctor may recommend an amniocentesis. They include: mother is over age 35; the couple has already had one child with a chromosomal abnormality; the couple has a close relative with a neural tube defect; a screening test, such as a sonogram, yielded an abnormal result.

What are the benefits of amniocentesis?
If the test indicates an abnormality, the information can be used to make vital decisions. Should the pregnancy be continued? Are there treatment options that can be pursued even during pregnancy? How can the family prepare for a baby with special needs? Early testing gives you time to cope with these big issues and make your best decision.

What are the risks of amniocentesis?
Although complications are rare, a small percentage of tests result in the leaking of amniotic fluid. There is also a small risk of infection or other complications that can lead to miscarriage.
