Patient's question:
I am 18 weeks pregnant. Last week, I had a color ultrasound. At that time, the doctor briefly introduced us to the screening test for Down syndrome. So far, the pregnancy has been going well with no abnormalities. I also want to undergo this test to further confirm the health status of the baby, but I don't know at which gestational week it is most appropriate to do it.What kind of help I need: When is the best time for the Down syndrome screening?
Doctor's answer:
Starting from the 14th week of pregnancy, as expectant mothers, we have a very important screening test, which is the screening for Down syndrome. Down syndrome is a congenital fetal malformation that we often encounter in clinical practice. It is caused by the formation of trisomy 21 during the development of chromosomes.
