Pairwise test, 11-14. It is also known as week screening test or nuchal thickness test.
What is Neck Thickness Test?
Dual Test: In the blood sample taken from the mother at the same time as the ultrasonographic examination performed between the 11th and 14th weeks of pregnancy It includes calculating the risk of some common fetal abnormalities (such as Down syndrome) in that pregnancy with the laboratory screening test performed. What does measurement mean?
It is the ultrasound measurement of the fluid accumulation in the skin-subcutaneous space at the nape of the baby in the mother's womb. This fluid is normally present up to a certain limit in every baby. In cases where the NT measurement increases, the possibility of both chromosomal and structural disorders increases.
11-14. What is the purpose of this week's scan, double test?
The purpose of this ultrasound scan and test is to assess the risk of Down syndrome and other chromosomal abnormalities, to diagnose structural abnormalities that may be present in the fetus this week, to diagnose multiple pregnancies such as twins and triplets, and to diagnose and symptomatology. To diagnose pregnancy loss that does not give birth.
11-14. What does the week test (double test) consist of? What is the detection percentage of Down syndrome?
11-14. In the risk calculation made in the week, the age of the mother, the levels of PAPP-A and Free Beta hCG measured in the mother's blood, the nuchal thickness of the fetus measured by ultrasound, the blood flow of the baby's nasal bone, the baby's heart and ductus venosus are given. Down syndrome detection rate is around 97.5% with all these markers.
