Lesedi and her doctor need to know as quickly as possible (hopefully within 24 hours) whether the child she has been carrying for only nine weeks possesses any genetic abnormalities. Which technique is Lesedi's doctor most likely to employ?

Question

Chorionic villus sampling (CVS) is a prenatal test that can detect genetic abnormalities in a developing fetus as early as 9-14 weeks of pregnancy, which makes it the best choice in Lesedi's situation. It involves taking a small sample of tissue from the placenta and testing it for genetic disorders. Ultrasound and genetic counseling can provide additional information, but they are not as effective at detecting genetic abnormalities as CVS. Amniocentesis is another prenatal test that can detect genetic abnormalities, but it is typically performed at 15-20 weeks of pregnancy, which is later than Lesedi's preferred timeline.
