The ultrasound aneuploidy screening is performed to estimate the risk of possible aneuploidy development, specifically Down syndrome. The screening test doesn’t confirm the chromosome status of the baby, but it evaluates the risk of having a baby with the Down syndrome and suggests the need for further diagnostic tests.
The ultrasound screening includes two procedures. First one is nuchal translucency test (NTL) or the first trimester screening scan which is performed between 11-14 weeks of the pregnancy. The second procedure is the anomaly scan or the second trimester screening scan which is performed between 18-20 weeks.
Ultrasound screening combined with hormone blood tests of the mother lets you accurately assess the risk of the Down syndrome development.
