MIA PETERSON is not a fan of tests. Because she has Down syndrome, she says, she cannot always think as fast as she would like to and tests end up making her feel judged. A recent driving test, for instance, ended in frustration.

Ms. Peterson, 31, the chief of self-advocacy for the National Down Syndrome Society, prefers public speaking and travel. And her test aversion extends to the latest one designed to detect Down in a fetus. "I don't want to think like we're being judged against," Ms. Peterson said. "Not meeting their expectations."

Heralded in the Nov. 10 issue of The New England Journal of Medicine, the new prenatal test provides earlier, more reliable results for all women than the current test, which is routinely offered to only older women who are at higher risk. But for people with Down syndrome and the cluster of other conditions subject to prenatal screening, the new test comes with a certain chill.

Because such tests often lead to abortions, people with conditions from mental disability to cystic fibrosis may find their numbers dwindling. As a result, some fear, their lives may become harder just as they are winning the fight for greater inclusion.
