Cell Free DNA: A New Non-Invasive Test for Downs Syndrome

April 4, 20167 min
The cell-free fetal DNA test is a relatively new test that may be used to assess the risk of a pregnant woman's developing baby having a chromosome disorder, such as Down syndrome, Edwards syndrome, or Patau syndrome. It may be used to identify other rare conditions resulting from an extra chromosome or missing piece of chromosome.Cell-free fetal DNA is genetic material that is released by the placenta and circulates in a woman's blood during pregnancy. It is present in small quantities starting in the first trimester and increases throughout pregnancy. CffDNA generally reflects the genetic makeup of the developing baby. Sean P. Kenney, MD, with the Center for Maternal & Fetal Care at Bryan Health, is here to help you better understand this procedure and how it can help determine health risks to an unborn child.
