If pregnant women want to undergo Down syndrome screening, they need to understand the relevant methods and cannot choose randomly. Some pregnant women choose these methods without sufficient protective measures, which often leads to many negative effects. So pregnant women should be cautious and understand the precautions for screening. Does the DNA Down syndrome screening require fasting?
Pregnant women do not need to undergo DNA Down syndrome screening on an empty stomach. They can consult a professional doctor first to understand the examination process, which can promote the operation of the examination and ensure a smooth examination process. The more common methods are Down syndrome screening and serum chorionic gonadotropin testing, which can not only understand the pregnant woman's due date and the health level of blood drawn, but also grasp the baby's brain development and genetic health.
Pregnant women undergoing Down syndrome screening can understand the condition of neural tube defects. If there are developmental abnormalities in the nervous system of pregnant women, the relevant reasons can often be analyzed through these methods, and the correct nursing measures can be selected to ensure the accuracy of Down syndrome screening. If there is suspicion that the baby has symptoms of Trisomy 21 or Trisomy 18, this screening method can also be used to determine.
Pregnant women should also control the timing of Down syndrome screening, usually around 15 weeks of pregnancy. Of course, most pregnant women are too familiar with these operating procedures, so it is important to understand them before the examination.
