Can Down Syndrome be detected on an ultrasound?
The thickness of the skin fold in the child’s neck is measured by ultrasound during the week of pregnancy and can thus be used to detect between 75 and 80 percent of all fetuses with Down’s syndrome because the neck fold is thicker in these. The examination of the nuchal fold or nuchal translucency is also referred to as an “NT test”.
What is the probability of Down Syndrome?
There are 30,000 to 50,000 people with Down syndrome in Germany and 100,000 to 150,000 in the USA. It is estimated that there is one in 650 births with trisomy 21. The higher the childbearing age (about 35 years and older), the risk of having a child with this disease seems to increase.
What is the probability of trisomy 21?

Can the neck fold recede?
Up to the 14th week of pregnancy, the lymphatic fluid builds up there because the lymphatic system and the kidneys are not yet fully developed. After the 14th week of pregnancy, the nuchal fold recedes, so that a later examination is pointless.
