Performance of non-invasive prenatal testing for trisomies 21 and 18 in twin pregnancies
Background Cell-free fetal DNA in maternal plasma represents a source of fetal genetic material that can be sampled noninvasively. There are ample studies confirming the accuracy of NIPT in singleton pregnancies, but there is still relatively little ...
