Amniocentesis, also known as amniotic fluid testing or AFT, is a diagnostic or therapeutic medical procedure primarily used in prenatal diagnosis of chromosomal abnormalities and fetal infections.

A small amount of amniotic fluid (15-20 ml), which contains fetal tissue, is extracted from the amniotic sac surrounding a developing fetus, and the fetal DNA is examined for genetic abnormalities. It is usually performed under ultrasound guidance and is performed between the 15th-20th week of pregnancy. If performed after 20 weeks it is often termed a late amniocentesis.
