Dr. Karl Muench

About 30 cc: About 30 cc of the approximately 300 cc of amniotic fluid present at the usual time of amniocentesis for prenatal diagnosis. The amount removed causes no harm and is rapidly restored from the maternal circulation.
Dr. Stephen Pappachen

15-20 cc: It is important to have an adequate amount for testing.
