Women who are ≥ 35 years old at their expected date of delivery (EDD) qualify for an NT ultrasound to be done in conjunction with first and second trimester serum markers (IPS).
In order to ensure the quality of an NT ultrasound, every sonographer must annually perform a minimum number. In order to maintain this minimum number in Northern Health and the East Kootenay/Kootenay/Boundary regions, pregnant women 30 years and older from these areas are eligible for an NT ultrasound as part of IPS.
The other eligibility criteria for NT to be done in conjunction with serum biochemistry (IPS) include:
- Women with twin pregnancies
- Women who have a history of a previous child or fetus with Down syndrome, trisomy 18 or trisomy 13
- Women who are HIV positive;
- Women pregnant following invitro fertilization (IVF) with intracytoplasmic sperm injection (ICSI).
