A nuchal translucency screening, or NT screening, is a specialized routine ultrasound performed between week 11 and week 13 of pregnancy. Fetuses with increased fluid at the base of their necks — a spot known as the nuchal fold — may have a chromosomal problem such as Down syndrome.

Usually it is not inherited, so a baby can be affected even if there is no history of Down syndrome in the family.
Although Down syndrome occurs more frequently as mothers get older, about 70 percent of babies with Down syndrome are born to women who are younger than 35 years old. Down syndrome is always associated with mental retardation and is often associated with physical problems such as heart defects and difficulties with sight and hearing. It is not possible to assess the degree of handicap before the baby is born. About nine out of 10 babies with Down syndrome will survive their first year, and nearly half of these will reach 60 years of age.
The First Trimester Test is performed between 10 and 13 completed weeks of pregnancy to screen for Down syndrome – this test is not used to screen for open neural tube defects. It combines information from an ultrasound examination of your baby with maternal blood analysis. It is suitable for women of all ages.
