Amniocentesis (also referred to as an amniotic fluid test) is a medical procedure used primarily in prenatal diagnosis of chromosomal abnormalities and fetal infections, as well as for sex determination. In this procedure, a small amount of amniotic fluid, which contains fetal tissues, is sampled from the amniotic sac surrounding a developing wrcch2016.com fetal DNA is then examined for genetic ICDCM: This complexity in risk assessment is also highlighted in the Society of Obstetricians and Gynaecologists of Canada Committee opinion on mid-trimester amniocentesis fetal loss rate , which.

Jul 07, · The offering of amniocentesis or chorionic villus sampling (CVS) for chromosome studies is recommended for pregnant women at high risk for Down syndrome. The offering of screening for Down syndrome by serum multiple-marker testing is recommended for all low-risk pregnant women, and as an alternative to amniocentesis and CVS for high-risk women.
