A nuchal translucency scan is combined with the mother’s age and results of a blood test showing the mother’s pregnancy hormone levels to provide a ‘combined risk’.Without the blood test, screening is 75% accurate for predicting Down syndrome.These days, it's pretty much routine for women in their second trimester to be scheduled for a level 2 ultrasound, commonly called the 20-week anatomy scan.That's because practitioners have found that this special pregnancy ultrasound is a great way to see how a baby is developing and offer reassurance that everything is going exactly the way it should be.
During the scan, you may be able to spot your baby's beating heart, the curve of the spine, and the face, arms and legs.
Important to know before you head into your scan: Very few babies showing soft markers (choroid plexus cyst, echogenic foci or pyelectasia, to name an unpronounceable few) end up having an abnormality.
Your practitioner will let you know whether any follow-up testing is necessary (it often isn't).
The scan uses ultrasound to screen for Down syndrome, or other chromosomal or inherited conditions in the foetus.
Other non-chromosomal conditions, such as neural tube defects, abdominal wall defects, limb abnormalities and some congenital heart disease, can also be detected at this stage of the pregnancy.
