Patient's question:
Ten days ago, I started working at a wooden floor store and have gained some experience. I would like to ask, can the Down syndrome screening check the health of the fetus? If so, at what month should it be done?Doctor's answer:
Hello, generally it is about 100 dollars. Before doing Down screening, you must have an ultrasound examination to check the fetal biparietal diameter. If the fetal biparietal diameter is between 28-48, then it can be done. Down syndrome is a screening for fetal abnormalities (such as congenital idiocy). It is best to do it. Usually, it is recommended that older pregnant women (age over 35 or carrying twins) do not undergo Down screening. Due to the certain false positive rate of Down screening, it is usually necessary to take amniotic fluid to confirm the high-risk diagnosis. Therefore, it is usually recommended that elderly women undergo amniocentesis directly. It is recommended to perform Down screening for pregnant women between 14-20 weeks.
