Question

Quizplus · Accepted Answer

Ultrasound is a non-invasive prenatal test which uses high-frequency sound waves to create an image of the developing fetus. It does not require insertion of any instruments into the body. Amniocentesis and chorionic villi sampling are invasive tests that involve sampling of amniotic fluid or fetal tissue through insertion of a needle or catheter into the uterus. Inserting a shunt into a fetus with water on the brain is a medical intervention, not a prenatal test.
