Amniocentesis (Overview)

Amniocentesis is a procedure used to draw a sample of the amniotic fluid that surrounds and cushions the baby in the womb. This fluid contains cells that have been sloughed off of the developing fetus. Amniocentesis is most often used to detect genetic abnormalities, though the results can also reveal the baby's sex, gauge lung maturity (if done close to term), detect amniotic fluid infections, or spot other pregnancy complications.

Should I have cvs or amniocentesis?

Should I have cvs or amniocentesis?

Maybe: CVS and amniocentesis are tests that some patients will choose to have to help get a diagnosis. They allow testing of the baby's genes and help diagnosis genetic defects. These tests are not done routinely on everyone but rather on those who are at high risk for genetic diseases. Age > 35 or an abnormal blood test for Down syndrome would be examples of those who might consider this. ...Read more

Is it safe to get an amniocentesis?

Yes: There are 2 main reasons amniocentesis is done. Genetic amnio is done at 16-18 weeks, testing for down's or other chromosome problems. There is a 1 in 3-400 chance that you could lose a pregnancy because of it. The other reason is to test for the baby's lung ability to breathe well. This is generally done between 35-38+ weeks. The only risks are that you might deliver. ...Read more

What are the risks of an amniocentesis?

Risks vs benefits!: The risks of amniocentesis include infection and bleeding, and miscarriage, i.e., losing the pregnancy. Pregnancy loss is not likely to occur, but it can. The question is: what will you do with the information you get? Many couples abort fetuses with chromosomal abnormalities - others do not. If you are sure you would not abort a fetus, the risk of having an amnio may not be worth it - to you. ...Read more

Where do I go to get an amniocentesis done?

Depends on reason: Amniocentesis is the procedure by which fluid is removed from the amniotic sac. It is done to study chromosomes, perform genetic tests, check lung maturity, etc. In general, it is performed by an obgyn specialist or a maternal-fetal medicine subspecialist in the office or clinic. It might also be performed on labor and delivery or the antepartum ward. Ask the OB provider what is best in your case. ...Read more

Is there a recovery period after amniocentesis?

Is there a recovery period after amniocentesis?

Yes: Minimal. Women walk out of the office after an amnio. From the mother's point of view the recovery is no different from having gotten an immunization - a little soreness at the needle site. Women should rest a bit if they are feeling contractions after the amnio, which is not uncommon for a short period of time. ...Read more
