WebFetal Fraction. The percentage of total cell-free DNA (cfDNA) in a sample derived from the fetus is called the fetal fraction—which can affect the ability of NIPT to detect fetal aneuploidy. When considering various cfDNA NIPT technologies, it’s important to understand how fetal fraction is used and how it can affect test results. Webif nipt is positive for t21 regardless it's just a positive nipt and you have to work that up with diagnostic testing regardless of FF%. in your case 15% is not really high. It's a normal FF had your nipt been negative but unfortunately it was not. She was saying that in comparison to the other trisomies the t21 is "higher".
