What is a normal nuchal translucency measurement at 12 weeks?

What is a normal nuchal translucency measurement at 12 weeks?

At 12 weeks of gestational age, an “average” nuchal thickness of 2.18mm has been observed; however, up to 13% of chromosomally normal fetuses present with a nuchal translucency of greater than 2.5mm.

What is a good result for nuchal translucency?

What is a normal nuchal translucency measurement? An NT of less than 3.5mm is considered normal when your baby measures between 45mm (1.8in) and 84mm (3.3in) . Up to 14 weeks, your baby’s NT measurement usually increases as they grow. But after this, extra fluid can be reabsorbed.

What is a low risk NT measurement?

The nuchal translucency measurement is more than just a screening for Down syndrome. A very small nuchal translucency measurement – less than 2.5 mm – places the pregnancy in a low-risk group for problems, such as fetal heart abnormalities.

Is 3.2 nuchal translucency normal?

First trimester measurement of NT at 12 weeks of gestation was 3.2 mm during the routine first trimester screening. The normal range of NT for this age is 1.1-3 mm.

Can a thick nuchal translucency be normal?

Many healthy babies have thick nuchal folds. However, there is a higher chance for Down syndrome or other chromosome conditions when the nuchal fold is thick. There may also be a higher chance for rare genetic conditions.

Can nuchal translucency go away?

Studies have shown that in normal fetuses the fluid collection known as NT increases with gestational age until about 13 weeks’ gestation3 and usually disappears after 14 weeks3, 4.

Does thick nuchal fold mean Down syndrome?

Many studies have shown that a thickened nuchal fold in a second-trimester fetus is a sonographic sign suggestive of a high risk for Down syndrome. These series have included fetuses already at risk for aneuploidy because of advanced maternal age or abnormal maternal serum alpha-fetoprotein (AFP) levels.

Do I need to get nuchal translucency screening?

Nuchal translucency screening is a type of ultrasound examination that is done in the first trimester to scan for certain medical conditions. It’s often combined with a blood test.

How long do nuchal results take?

In general, the thicker the nuchal translucency at a given gestational age, the higher the chance of a chromosomal problem. You may get the results right away, or you may have to wait up to 10 days if the doctor has to send the data to a processing center.

What does the nuchal scan test for?

The nuchal translucency scan (also called the NT scan) uses ultrasound to assess your developing baby’s risk of having Down syndrome (DS) and some other chromosomal abnormalities, as well as major congenital heart problems. The NT scan measures the clear (translucent) space in the tissue at the back of your baby’s neck.

What does nuchal mean?
