Prenatal screenings can identify problems with your health, such as anemia or gestational diabetes. Pregnancy screenings take place during the first, second, and third trimesters. A nuchal translucency NT scan screens your baby for these abnormalities. This test is typically scheduled between weeks 11 and 13 of pregnancy. An NT scan is a common screening test that occurs during the first trimester of pregnancy. But too much clear space can indicate Down syndrome, or might show another chromosome abnormality like Patau syndrome or Edwards syndrome. Our body cells have many parts, including a nucleus. The nucleus holds our genetic material. In most cases, the nucleus has 23 pairs of chromosomes, which are equally inherited from both parents. Individuals born with Down syndrome have an extra copy of chromosome

12 week pregnancy dating scan: here’s what to expect
Nuchal translucency is the name for the normal fluid space behind the neck of a foetus unborn baby that can be seen on ultrasound scans. A nuchal translucency scan also called first trimester of pregnancy screening is carried out during weeks 11—13 of a pregnancy. 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. Screening can determine the likelihood of risk of an abnormality, but does not diagnose the condition. If screening does identify a possible risk, it does not necessarily mean there is an abnormality present, but does mean that further testing is necessary.
A dating scan is an optional early ultrasound to confirm your due date. At weeks, a nuchal translucency scan and blood test is offered.
This combined test is an extremely accurate non-invasive screening test available to help identify a fetus at risk for Down syndrome as well as other chromosomal abnormalities and some major structural abnormalities. The sensitivity of this only recently eclipsed by NIPT. An ultrasound screening test is non-invasive and does not have any side effects or complications.
The only way to diagnose Down syndrome or other chromosomal abnormalities is by having a diagnostic test — either a CVS or an amniocentesis — and testing the fetal cells. These tests are invasive and require a needle to be passed into the maternal abdomen and uterus and therefore carry a small risk of miscarriage. Many patients do not wish to have the diagnostic test because of the small risk of miscarriage and prefer to have the ultrasound screening test, the NT scan, to help them decide if they wish to proceed to testing the fetus.
Unfortunately, while NT combined with the first trimester biochemical blood test is a very accurate screening test available for chromosomal abnormalities, it will not detect all fetuses affected with Down syndrome or other chromosomal abnormalities. Chromosomal abnormalities occur when there is a change in the number or structure of the chromosomes. Normally we have 46 chromosomes, 23 pairs numbered and a pair of sex chromosomes.
