The baby's NT was 2.2mm, well within the normal range so the high risk result was due to age (38) and also a slightly higher hcg level. Therefore, the risk of fetal karyotype abnormalities increases with the increased number of ultrasound soft markers, and multiple genetic tests, including NIPT, are more feasible for this population. Restate the SMFM recommendations for the role of ultrasound in the era of non-invasive prenatal screening for fetal aneuploidy. You'll receive a low-, moderate-, or high-risk result. False-positive results can occur in the presence of placental mosaicism, vanishing twin syndrome, or an unidentified maternal condition, such as mosaicism or cancer.
