The cfdna revealed 95.75% sensitivity and 100% specificity in rhd positivity and 100% sensitivity and 95.45% specificity in sry positivity. Dna strands from the pregnancy and from the woman are circulating in the womans blood.] The nipt/cell free dna screening performance calculator (calculator), also known as nipt/cfdna performance calculator, is provided solely for use by healthcare professionals with an understanding of positive predictive value (ppv) and negative predictive value (npv).

Small fragments of fetal dna that cross the placenta and enter the maternal blood. A cfdna screening checks this dna to find out if the baby is more likely to have down syndrome or. Our superior equipment and testing methodology make this possible.
