Fetal Fraction Chart

Fetal Fraction Chart - Web the ability to detect fetal chromosomal aneuploidies is directly related to a sample’s fetal to total dna fraction, known as the fetal fraction (ff). In some studies, failed nipt results due to low ff are associated with an increased risk of aneuploidy. Web the fraction of all dna circulating in the mother’s blood that originates from the fetus is called the fetal fraction (ff), expressed as a percentage value. The minimum ff is considered 4%, and the test result below 4% is uncertain due to low fetal fraction (lff). The minimum ff is considered 4%, and the test result below 4% is uncertain due to low fetal fraction (lff). Biologically, gestational age of up to. In patients who weigh more than 250 pounds (113 kg), 10% may have a fetal fraction of less than 4% (49). Because of the effect of fetal fraction on test accuracy, a laboratory test that reports fetal fraction is preferred.
