Researchers at Tel Aviv University developed a new blood test to find genetic abnormalities in fetuses from 11 weeks on into pregnancy.

This new test led by Prof. Noam Shomron of TAU’s Sackler School of Medicine was published last week in the Genome Research Journal. The blood test enables doctors to diagnose genetic disorders caused my impairments in the fetal genome by sampling DNA from both the mother and father’s blood.

After the blood is sampled a computer algorithm produces a “map” of the baby’s genome identifying abnormalities with over 99% accuracy.

“Non-invasive prenatal tests are already available for chromosome disorders such as Down syndrome,” said Prof. Shomron.

While genetics have for a long while have been able to detect Down syndrome, the new process and algorithms will allow doctors to detect many more diseases that were, in past years, harder to detect before the actual pregnancy.
