Nuchal Translucency (NT) Scan in Chennai

Overview of the Nuchal Translucency (NT) Scan

The nuchal translucency (NT) scan in Chennai is a prenatal screening test performed between the 11th and 14th weeks of pregnancy. This ultrasound examination measures the clear space in the tissue at the back of the foetus's neck, known as the nuchal fold. The purpose of the NT scan is to assess the risk of chromosomal abnormalities and genetic conditions in the foetus, such as Down syndrome, Edwards syndrome, and Patau syndrome. Although the NT scan does not provide a definitive diagnosis, it helps identify pregnancies that may require further testing. The nuchal translucency test is often combined with first-trimester blood tests to enhance the accuracy of predicting chromosomal disorders.

Cost of Nuchal Translucency (NT) Scan

The NT scan cost in India varies depending on location, hospital, and package of tests included. In private hospitals and clinics, the NT scan price ranges from ₹2,500 to ₹6,000, while in government hospitals, it can cost between ₹1,000 and ₹3,000. Advanced diagnostic centres may charge between ₹3,500 and ₹7,000 for the NT scan sonography price, which may include the ultrasound and blood tests if they are part of the first-trimester screening package.

Use of Nuchal Translucency (NT) Scan

The nuchal translucency test is used to screen for various genetic and chromosomal conditions in the foetus. Some of the most common conditions that may require an NT scan include:

• Down Syndrome: This genetic disorder, caused by an extra copy of chromosome 21, is associated with intellectual disability and distinctive physical features. An increased NT scan measurement indicates a higher risk of Down syndrome.
• Edwards Syndrome: A rare genetic disorder caused by an extra copy of chromosome 18, often leading to severe developmental delays and physical abnormalities.
• Patau Syndrome: Another rare genetic disorder caused by an extra copy of chromosome 13, associated with severe intellectual disability and physical abnormalities.
• Turner Syndrome: A genetic disorder affecting females, caused by the absence of one X chromosome, which can lead to physical and developmental issues.
• Congenital Heart Disease: An increased NT scan measurement may also indicate a higher risk for congenital heart conditions, although it is not specific to these conditions alone.

What is the Procedure for Nuchal Translucency (NT) Scan in Chennai?

The procedure for a nuchal translucency test scan involves several steps:

• Preparation: For an abdominal ultrasound, patients should have a full bladder by drinking 2-3 glasses of liquid about an hour before the test. For a vaginal ultrasound, the bladder should be empty.
• Application of Gel: A water-based gel is applied to the abdomen to facilitate the transmission of sound waves.
• Ultrasound: The doctor uses an ultrasound transducer to capture images of the foetus and measure the thickness of the nuchal fold in millimetres.
• Measurement: The fluid-filled space behind the foetus's neck is measured, and the thickness of the nuchal fold is recorded.
• Interpretation: The measurements are interpreted in the context of gestational age, and the results are discussed with the patient. If the NT scan measurement is abnormal, further diagnostic tests may be recommended.

How to Prepare for Nuchal Translucency (NT) Scan

Preparing for a nuchal translucency test is relatively simple and involves the following steps:

• For an abdominal ultrasound, drink 2-3 glasses of liquid about an hour before the test to ensure a full bladder, which provides a clearer ultrasound picture.
• If a vaginal ultrasound is performed, make sure to have an empty bladder.
• There are no specific dietary requirements or restrictions before the NT scan.
• Wear comfortable clothing that allows easy access to the abdomen.

Who Can Opt for Nuchal Translucency (NT) Scan

Any pregnant individual between the 11th and 14th weeks of pregnancy can opt for a nuchal translucency test. The test is particularly recommended for:

• Women aged 35 or older at the time of delivery, as the risk of chromosomal abnormalities increases with maternal age.
• Couples with a family history of genetic disorders or previous pregnancies affected by chromosomal abnormalities.
  Pregnancies with abnormal first-trimester screening results or other risk factors identified during prenatal care.
• Individuals seeking additional reassurance about the health and development of their foetus.
