First national study of non-invasive prenatal testing shows it works and is preferred by high-risk women

Although non-invasive prenatal testing carries a much lower risk of miscarriage than do invasive tests, it is slightly less accurate, because it only analyses DNA from the outer layers of the placenta. In some cases a trisomy will be present in these outer layers, but not in the fetus. However, a large European study shows that high-risk women prefer NIPT.
