| What
to Know About Amniocentesis and Chorionic
Villus Sampling |

Would
you like to know if the baby in your uterus is
healthy?
If you are like most women, your answer will be
"yes."
As you may already know, there are numerous tests that
can be done during pregnancy to check for
abnormalities. Amniocentesis and Chorionic Villus
Sampling are two of these tests, whose main purpose is
to diagnose genetic or chromosomal defects, but can
also provide other valuable information, such as
paternity results.
These two tests are used for mothers who are at risk
for carrying a fetus with a congenital birth defect.
This includes women over 35, women with a history of
miscarriages or birth defects, and women with a family
history of genetic disease.
You may have never heard of amniocentesis or
chorionich villus sampling, or you may only have a
general idea of what's involved. Hopefully this
information can help you to be prepared and
comfortable if the need should arise for you to have
either of these tests done.
Amniocentesis
Amniocentesis is normally performed in the second
trimester, between the 15th and the 18th week of
pregnancy. Using an ultrasound as a guide, the health
care provider inserts a long needle into the abdomen
of the mother and draws out a small amount of amniotic
fluid. This test is more than 99% accurate in
diagnosing chromosomal disorders like Down syndrome
and Edward's syndrome. Unfortunately, there is a small
risk of miscarriage of about 0.5%-1% (1 or 2 cases out
of 200).
Chorionic Villus Sampling (CVS)
Chorionic Villus Sampling is normally performed in the
first trimester, between the 10th and 12th week of
pregnancy. Using an ultrasound as a guide, the health
care provider inserts a long, thin tube into the
vagina and through the cervix and removes a small
amount of chorionic villus from the outside of the sac
where the baby develops. Unfortunately, this procedure
has a slightly higher risk of miscarriage than
amniocentesis of about 1%-3% (1-3 cases out of 100)
