Fox News
Non -invasive prenatal testing (NIPT) on pregnant women to detect the risk of a fetus having rare genetic abnormalities may often be wrong, according to recent reports in the media. These tests, according to multiple health experts, can actually give false positives, which can create significant angst in expecting parents.
Genetic specialists and obstetricians told Fox that noninvasive prenatal testing works well for screening the fetus’ risks for common chromosomal disorders like Down syndrome but said the tests are not as accurate for relatively rare conditions associated with chromosomal microdeletions such as Wolf-Hirschhorn syndrome.
Dr. Siobhan Dolan, System Vice Chair for Research in the Department of Obstetrics, Gynecology and Reproductive Science at the Icahn School of Medicine at Mount Sinai in New York City, told Fox News that it is important for expectant parents to recognize that these types of maternal blood tests are screening tests and not actual diagnostic tests.
