For women who are concerned that they may be carrying a child with Down's Syndrome, testing  includes risky, invasive procedures that carries a 1% risk of miscarriage. But scientists now say that a new blood test, which could be available in about two years, will eliminate the risk of miscarriage while still delivering reliable results.

In a blind study of blood samples taken from 40 pregnant women, the test correctly identified 14 cases of Down's syndrome with no false positives. While this does seem promising, researchers still need to conduct a larger clinical trial in order to validate these results.

Details of the study can be found in the journal Nature Medicine.
