Patient's question:
Ten days ago, I started working at a wooden flooring store and have gained some experience. I want to ask, can the Down syndrome screening test check the health of the fetus? If so, at what stage of pregnancy 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 greater than 35 or 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 the Down screening for pregnant women between 14-20 weeks.
