lili, here's what it says on babycenter.com. if you haven't registered there you should. you can enter your due date and they will email you weekly updates of the baby's develpment which is really cool. tons of other good info there as well..
What is the nuchal translucency screening test?
This prenatal test (also called the NT or nuchal fold scan) can help your healthcare practitioner assess your baby's risk of having Down syndrome (DS) and some other chromosomal abnormalities as well as major congenital heart problems.
The NT test uses ultrasound to measure the clear (translucent) space in the tissue at the back of your developing baby's neck. Babies with abnormalities tend to accumulate more fluid at the back of their neck during the first trimester, causing this clear space to be larger than average.
The NT scan must be done when you're between 11 and 14 weeks pregnant. (The last day you can have it done is the day you turn 13 weeks and 6 days pregnant.) It's usually offered along with a blood test in what's known as first-trimester combined screening.
Like other screening tests, an NT scan won't give you a diagnosis. But it can assess your baby's risk for certain problems and help you decide whether you want to have chorionic villus sampling (CVS) or amniocentesis to find out whether your baby is actually affected.
