5 Perinatal and genetic outcomes associated with no call cfDNA results in 18,496 pregnancies

Failed or no call cell free DNA (cfDNA) testing confers an increased risk of aneuploidy, but few series include complete obstetric, infant, and genetic outcomes. We hypothesized that failed tests would be associated with aneuploidy and adverse perinatal outcomes. Secondary analysis of a multicenter prospective study of SNP-based cfDNA; confirmatory genetic testing was performed in all cases during pregnancy or after birth. Demographics,...
