Fetal fraction‐based risk algorithm for non‐invasive prenatal testing: screening for trisomies 13 and 18 and triploidy in women with low cell‐free fetal DNA

What is it about?

Current approaches to prenatal testing utilize the small amounts of fetal DNA (cell-free DNA) found in the mother's blood. Most tests cannot report on fetal risk if the levels of this DNA are too low, which can be caused by several factors. We developed an computational approach that takes two, gestational age and maternal weight, into account.
