"Another ominous point: Because this maternal blood test is so much safer than amniocentesis, more mothers will likely seek them out than in the past. More Down syndrome babies will be identified. And more of them will be aborted—in part because medical professional paint such a negative picture of what life will be like with a Down syndrome child.
It’s one thing to encourage parents to undergo prenatal testing if the purpose is to prepare them for what lies ahead, or if there’s something that can be done about a medical problem. It’s quite another matter to use testing as a search-and-destroy mission, identifying problems that cannot be solved—and then pressuring patients to abort and try again for a less “defective” child."
