Every pregnant woman who has considered getting a prenatal genetic test is familiar with the dilemma: Amniocentesis and chorionic villus sampling (CVS) are the only available diagnostic tests that can say for sure whether a fetus has a devastating genetic disorder—but these tests are invasive, and each carries a small risk of miscarriage. Now, researchers are developing a less invasive test that collects fetal cells from a maternal blood sample using an antibody-coated chip, allowing . . .
