GENETIC AMNIOCENTESIS

This procedure is often performed between 14 – 21 weeks, to rule out or identify chromosomal abnormalities.  Amniocentesis is often offered as an optional test when risks or concerns exist for genetic problems.  This procedure usually requires 45 minutes to complete.

This is a simple medical procedure used to obtain a small amount of the amniotic fluid surrounding the fetus.  An ultrasound is performed with the amniocentesis to check the position of your baby and to locate pockets of fluid.  The doctor will insert a needle into the amniotic sac to remove a few teaspoons of fluid for testing.  It usually takes 1 – 2 minutes.  Amniotic fluid contains cells from the fetus that can be tested.  These cells have the same genetic makeup as the fetus.
