Patient's question:
Still in the process of trying to conceive, I've already become a protected object in the family. As soon as I confirmed the pregnancy, the family became even more careful, couldn't be more careful. Today, my mom asked me when to do the Down syndrome screening, and I don't know. Hello, how many weeks pregnant can you do the Down syndrome screening?Doctor's answer:
Hello, according to your description, there are currently two methods for Down syndrome screening. One is the early NT detailed examination, which is recommended to be performed between weeks 11 and 13 of pregnancy. It involves using ultrasound to measure the thickness of the nuchal translucency. The other is prenatal screening, which is a blood test done on an empty stomach, recommended between weeks 15 and 20 of pregnancy, and the age should not be greater than 35 or 38 years old.
