Nuchal Translucency Scan

TYou’ll have several doctor visits and screenings from now until the birth of your child if you just found out you’re expecting. Prenatal screening is one. Having undergone an NT scan recently, if you have no clue how to read or check NT Scan Report, this post will guide you.

Background information – NT scan

The first, second, and third trimesters are when pregnancy screenings are conducted. 

A type of prenatal test called first-trimester screening or the nuchal translucency (NT), the scan gives your doctor early knowledge about the health of your unborn child, specifically your child’s chances for chromosome abnormalities.

Quality improvements to antenatal screening for Down Syndrome and other conditions were introduced in the year 2010.

 NT Scan Screening for Down Syndrome

This is a high-quality scan and is taken between 11-13 weeks to precisely measure the NT and CRL measurements. These are essential in providing pregnant women with an optimum risk result for antenatal screening.

During the process, generally, there is a tendency to under-measure the nuchal translucency. It is therefore important that the NT and CRL are measured correctly due to the amplification of errors that can occur when done otherwise. Ensuring to carry out the NT scan from a trustworthy scan center under the guidance of an expert fetal medicine specialist is hence essential.

How to check NT scan report?

NT scan report

The primary goal of an NT scan is to determine whether or not the developing fetus has Down Syndrome. We know your anxiety as parents-to-be. On receiving the NT scan report, you would naturally want to know everything about it. Here’s quick help.

A baby can be diagnosed with Down Syndrome in one of two ways:

NT above 3 millimeters in most pregnancies indicates a discussion of genetic counseling and additional testing.

To check your NT scan report here is an easy calculation.

Your baby should be between 45mm (1.8in) and 84mm in size for an NT of less than 3.5mm to be considered normal (3.3in).

Another way of putting is here;

1:30 means that out of 30 pregnant women with similar results, one baby will have Down Syndrome, while the other 29 will not.

1:4000 means that out of 4000 pregnant women with similar results, one baby has Down Syndrome while the remaining 3999 babies do not.

There will be less risk if the second number is high, such as 4000 in a ratio of 1:4000.

The outcomes can be divided into low-risk and high-risk categories. A cutoff of 1 in 350 is applied in these circumstances.

Because 1:30 is more dangerous than 1:350, it is regarded as high risk.

Since 1:4000 carries less risk than 1:350, it is regarded as low risk.

Nineteen of the twenty pregnant women who have an NT scan come back normal.

A note from Jammi Scans

A nuchal translucency (NT) scan can assist in determining the likelihood of your baby having a congenital or genetic condition. Don’t be alarmed if your results are unusual.

It does not indicate that your child has Down syndrome or another congenital syndrome. It could simply indicate that your baby is at a higher risk of developing these conditions.

What is even more important is obtaining a high-quality nuchal translucency and crown-rump length measurement during the scanning. To get the most reliable scan result, get in touch with an expert fetal medicine expert who is adept at using high-frequency transducers by various adjusting settings.

Create an opportunity to discuss the test results with your doctor. She may confirm the findings with additional tests such as chorion villus sampling or amniocentesis. As a result, you can decide whether or not to keep the baby.

If the NT is normal, your doctor will recommend a blood test in addition to the NT scan because it will provide a more accurate assessment of your chances. More prenatal testing may be required in some cases to determine your baby’s chances of being born with a genetic condition.
