Amniocentesis

Amniocentesis is a prenatal test that helps you learn if a fetus has health problems. The test is most often done between weeks 15 and 18 of pregnancy. Discuss with your doctor whether amniocentesis is right for you.

Preparing a patient for the test

Should You Have Amniocentesis?

If the fetus has a higher than normal chance of birth defects or other problems, you may want to have this test. The following risk factors can increase chances of fetal health problems:

  • You're 35 or older.

  • There's a history of inherited (genetic) problems in your family.

  • Other tests have shown that the fetus may have health problems.

How Is Amniocentesis Done?

  • First, the fetus is located with ultrasound (sound waves that make an image on a screen).

  • A thin needle is then inserted into your belly. The doctor keeps the needle from touching the fetus by watching the screen.

  • The needle is used to remove a small amount of fluid from your womb. Your body will make more fluid to replace what was taken.

  • You can go home right after the test. But you may need to take it easy for a day or so.

When to Call Your Doctor

Call your doctor right away if you notice:

  • Severe pain or cramping

  • Vaginal bleeding (spotting)

  • Fever or chills

  • Fluid leaking from your vagina

Getting Test Results

You'll learn your amniocentesis results in 2 weeks. Most results are normal. Even if yours aren't, it doesn't always mean there's a problem. You and your doctor can talk about other tests or special care you may want.
