Prenatal cell free dna (cfdna) screening is a blood test for pregnant women. during pregnancy , some of an unborn baby's dna circulates in the mother's bloodstream. a cfdna screening checks this dna to find out if the baby is more likely to have down syndrome or another disorder caused by a trisomy. a trisomy is a disorder of the chromosomes . This is called cell free fetal dna testing, or more commonly, non invasive prenatal testing ( nipt ), and it can be performed very early in the pregnancy. the uptake of nipt around the world has been remarkable, with literally several million pregnant woman getting this test each year. however, it is important to know that the american college.
