Diagnostic testing after positive results on cell free DNA screening: CVS or Amnio?

12 Aug 2021

Abstract excerpt

OBJECTIVE: The positive predictive values of cell free DNA (cfDNA) and rates of confined placental mosaicism (CPM), imprinting and other factors vary by chromosome. METHODS: We sought to review the literature for each of these features for each chromosome and provide recommendations on chorionic villus sampling (CVS) versus amniocentesis after an abnormal cfDNA result. RESULTS: For chromosomes with high rates of...
