A first-trimester screening test can reliably identify fetuses likely to be born with Down syndrome, providing expectant women with that information much earlier in a pregnancy than current testing allows, according to a major study being released today, 11/09.

The first-trimester approach identified 87 percent of Down babies when used at 11 weeks, whereas the later quadruple test identified 81 percent. The two tests together picked up 95 percent of cases. Both produced false positives in about 5 percent of cases.
