Screening protocols which use NT together with maternal serum markers at 10–13 weeks can achieve a much better screening performance than do second-trimester serum-only. If it's abnormally large, containing more fluid than usual, it may indicate Down syndrome (trisomy 21) or another genetic condition called trisomy 18.
