Nuchal Translucency Screening: What It Tells You
Nuchal translucency (NT) screening is a first-trimester ultrasound that measures the thickness of the fold of skin behind your baby’s neck. That measurement helps assess the chance of chromosomal conditions and certain other findings, such as heart concerns. It’s performed between 10 weeks 6 days and 13 weeks 6 days. Remember that it’s a screening: it estimates chances, it doesn’t diagnose.
A first, gentle look, explained simply
The nuchal translucency screening is a straightforward ultrasound. A licensed sonographer measures the thickness of the skin fold behind your baby’s neck. That single measurement is meaningful: it helps assess the chance of chromosomal conditions, and it’s also used to evaluate the chance of other findings, such as certain heart concerns.
When it’s done and what to expect
The screening is performed in a specific window, between 10 weeks 6 days and 13 weeks 6 days, when the measurement is most reliable. During the appointment, your sonographer takes a minimum of three measurements while your baby is in an acceptable position, to ensure accuracy.
About certification, and why it matters here
Patients sometimes ask whether a practice can be “certified” for NT measurement through bodies like the FMF or NTQR. There isn’t a way to certify a practice as a whole through those organizations. What matters is the certification of the people doing the work, and in our practice, the providers overseeing the measurement, the person performing it, or both, have been certified. The expertise sits exactly where it should: with the people measuring.
If you’ve received an elevated result
First, take a breath. This is the single most important thing to understand: an NT screening is a screening, not a diagnosis. An elevated result is not, by itself, confirmation of a problem. It means a closer look is the sensible next step, usually further follow-up or additional testing to give you a clearer picture. Many pregnancies with an elevated NT result go on to be perfectly healthy.
You won’t be left wondering
Whatever your result, you’ll have a specialist who explains what it means in plain terms and lays out your options. From the first measurement onward, this is something we navigate together.

“Saw them with my first pregnancy in hospital and they were great. When I got pregnant with my 2nd son 2 years later needed to be followed by a high risk dr and saw them again and they remembered me. Very compassionate and knowledgeable. If I decide to have a 3rd will definitely see them again. Great office staff too.”
