Who qualifies for NT as part of IPS?
As of March 2011, women who are ⩾35 years old at their expected date of delivery (EDD) qualify for an NT ultrasound to be done in conjunction with fi rst and second trimester serum markers (IPS). In order to ensure the quality of NT ultrasound, every sonographer must annually perform a minimum number.

Women who have a higher order multiple pregnancy (at any age) qualify for an NT ultrasound alone.
