Study: new test could eliminate risk for down syndrome testing

A simple, new blood test could help pregnant women eliminate some of the risk that comes from traditional testing for down syndrome.

The test analyzes a mother's blood, which has a tiny amount of DNA from the fetus. The study accurately detected each case of down syndrome, but it mistakenly identified the condition in 2 percent of the cases.

Still, it could give pregnant women a genetic testing option other than amniocentesis and CVS -- which are both invasive procedures that carry the risk of miscarriage.

The study is published in the British Medical Journal.
