Amniocentesis, or an Amniotic Fluid Test (AFT), is a medical procedure used for prenatal diagnosis, in which a small amount of amniotic fluid is extracted from the amnion around a developing fetus. It is usually offered when there may be an increased risk for genetic conditions (i.e., Down syndrome, sickle-cell disease, cystic fibrosis, etc) in the pregnancy.
Amniocentesis can be done as soon as there is enough amniotic fluid surrounding the fetus that a sample can be removed safely. Early amniocentesis can be performed as early as 13 weeks gestation. Standard amniocentesis is usually performed between 15 and 20 weeks gestation. Results take about two weeks. Often, genetic counseling is done before amniocentesis, or other types of genetic testing, is offered.
Risks
Amniocentesis is slightly less risky to the child than chorionic villus sampling although villus sampling can be done earlier. Amniocentesis done in the second trimester is often said to have a risk of foetal death between about 1 in 400 and 1 in 200. More on [ Amniocentesis ]
