ULTRASOUND NUCHAL TRANSLUCENCY
The Nuchal Translucency (NT) is a collection of fluid under the skin at the back of the baby’s neck that can be measured using ultrasound. All babies have some fluid, but in many babies with Down’s syndrome, the NT is increased.
Nuchal Translucency ultrasounds are performed as early as 11weeks, 6 days to a maximum of 13 weeks, 6 days gestational age.
Along with serial blood tests, the NT ultrasound is a screening test that can estimate the risk of your baby having Down’s. In specific cases, it is offered along with blood tests to determine fetal risk for certain abnormalities. The NT ultrasound can help you decide whether or not to have a diagnostic test such as amniocenteses, which will give you a definite diagnosis but carries a small risk of miscarriage.
In order for the Medical Services Plan of British Columbia to cover this exam the patient must meet at least one of the following criteria:
Over 35 years old at their expected date of delivery
Multiple gestations (twins)
History of a previous child or fetus with Down's Syndrome, Trisomy 13 or 18
