How does prenatal cell free DNA screening work?
Overview. Prenatal cell-free DNA (cfDNA) screening, also known as noninvasive prenatal screening, is a method to screen for certain chromosomal abnormalities in a developing baby. During prenatal cell-free DNA screening, DNA from the mother and fetus is extracted from a maternal blood sample and screened for the increased chance for specific…
