NT Scan in Chennai
The NT scan in Chennai is a safe and important early pregnancy ultrasound that helps assess the risk of certain chromosomal conditions in your baby. At Unittas Hospital, we provide this gentle screening with expert care to give you reassurance during this special time. The nuchal translucency scan (also called nuchal translucency ultrasound) measures the small amount of fluid at the back of your baby's neck using ultrasound. It is part of first-trimester screening and looks at the chance of conditions like Down syndrome, Edwards syndrome, or Patau syndrome. It is not a definite diagnosis but helps calculate risk when combined with other factors.

What is the NT Scan?
This quick ultrasound checks the thickness of fluid under the skin at the back of the baby's neck (nuchal translucency). A thicker measurement can suggest higher risk for chromosomal issues or sometimes heart problems, while a normal measurement is reassuring.
When is the NT Scan Recommended?
It is usually done between 11 and 14 weeks of pregnancy (most often around 12 weeks). Doctors suggest it as:
Part of routine first-trimester screening
For all pregnant women who want early information
If there are factors like maternal age or family history
Alongside a blood test for more accurate risk assessment
It is optional, and your doctor can discuss if it suits your pregnancy.
NT Scan Procedure
The NT scan procedure is simple and non-invasive:
You lie comfortably on an exam table.
A clear gel is applied to your tummy.
An ultrasound probe is gently moved over your abdomen to get clear images of the baby.
In some cases, a transvaginal scan may be used for better views.
The sonographer measures the nuchal fluid carefully.
The whole process takes about 20 to 30 minutes and is painless.
You can often see your baby on the screen during the scan.
Preparation for the NT Scan
- Little preparation is needed:
- Drink plenty of water before the appointment so your bladder is comfortably full (this helps get clearer pictures).
- Wear loose, comfortable clothing that allows easy access to your abdomen.
- Eat normally; no fasting required.
- Bring any previous scan reports or blood test results if advised.
Understanding Your NT Scan Report
The NT scan report shows the measurement of the nuchal translucency in millimetres, along with a risk calculation. This combines the NT value with your age, exact pregnancy stage, and often blood markers.
NT scan price
The NT scan price in Chennai is affordable, usually ranging from INR 1,000 to INR 3,000 depending on the centre and if combined with other checks. At Unittas Hospital, we offer transparent and reasonable pricing to make this essential screening easy for expectant parents.
What the Results Mean
A normal measurement (typically less than 3.0 to 3.5 mm, depending on exact weeks and baby size) suggests low risk.
A higher measurement may indicate increased risk, but most babies with slightly higher values are healthy.
Your doctor explains the full risk figure (like 1 in 1,000 low risk or 1 in 150 higher risk) and may suggest next steps, such as more tests if needed.
The scan is highly accurate for screening when done by trained experts.
