An obstetrician knows that one of her patients is a pregnant woman whose fetus is at risk for a serious disorder that is detectable biochemically in fetal cells. the obstetrician would most reasonably offer which of the following procedures to her patient?
a) cvs
b) ultrasound imaging
c) amniocentesis
d) blood transfusion
e) x-ray
