Needs Evaluation: Nt at 13 wks was borderline high. Nasal bone measurement at 21 wks is rather low since lower range of normal would be 4.4mm. In up to 15% of fetuses with nasal bone hypoplasia there were no other findings of aneuploidy. So, there is certainly a degree of risk here. You may want to consider amniocentesis to be better prepared if there is a problem and relieved if there is not. Good luck!
