Procedure where fluid is withdrawn from the abdomen and reveals chromosomal abnormalities and certain metabolic disorders in the fetus

Amniocentesis

Explanation:

Amniocentesis is usually done at 14-16 weeks of pregnancy. It tests a sample of the amniotic fluid in the womb for genetic defects (the cells found in the fluid and the fetus have the same DNA). Under local anesthesia, a thin needle is inserted through the woman's abdomen and into the womb.
