What is nuchal translucency?


Nuchal translucency is a test that is commonly performed at the end of the first semester of pregnancy as one of many screening tests for potential birth defects.

Nuchal translucency refers to the fluid sac found at the back of the neck of the fetus, which can give an indication of an increased risk for the baby to have a chromosomal defect. T
his test is not 100% accurate and will be used in combination with other tests, such as a blood test if the results come back positive for a more conclusive test result.

Nuchal translucency testing is optional but must be completed before the 13-week mark.
After that point, the tissue being measured loses its translucency and the test results will come back as inconclusive.

Nuchal translucency testing is done using ultrasound testing equipment that is very safe for both the baby and mother, with the sonographer using it to take a measurement of the fluid at the back of the baby’s neck.

What does nuchal translucency test for?


Nuchal translucency is a commonly performed test for pregnant women at the end of their first semester to check for the likelihood of the baby having or developing a chromosomal defect.

A nuchal translucency test measures the size of the fluid sac found at the back of the baby’s neck in the womb.

This sac is normal and intended to be there, however, the size of it has been shown to be an indication that the baby may have a defect such as Down Syndrome or other chromosomal disorders.

A nuchal translucency test is often performed during the standard first-trimester ultrasound and is done in conjunction with other tests, such as blood tests, in order for the doctor to identify any risks or likelihoods that the baby will be born with a defect.

Women can choose to opt out of having the test done, however, they can’t go back and have the test done later on in their pregnancy as the tissues will no longer be transparent and the test results will be inconclusive.

Who should have a nuchal translucency scan?


A nuchal translucency scan is offered to all women as part of the several routine screening tests done throughout the pregnancy.

This particular test must be performed no later than 13 weeks into the pregnancy as the tissues lose their translucency after that point and can’t be accurately measured.

Provided a woman finds out she is pregnant before the end of her first semester, she will be offered the nuchal translucency test. It is recommended for all women; however, women do have the ability to opt-out if they so choose.

For women who are already considered high risk for having a child with a chromosomal birth defect, such as Down Syndrome, it is highly recommended that they have the test done, along with other screenings to identify the likelihood that their baby will be born with a defect.

The likelihood of the baby having one of these abnormalities can be determined based on the size of the fluid sac that is measured during the ultrasound.

Does nuchal translucency go away?


A nuchal translucency scan should be completed at the end of the first trimester of a woman’s pregnancy, typically between 10 and 13 weeks.

After the 13th week of the pregnancy, the tissues that are measured lose their translucency and are unable to be accurately measured for conclusive test results.

Women can choose whether or not they want to have a nuchal translucency test done, however, if they opt-out in the first trimester, they won’t be able to have the test done later on for this reason.
