Can Down syndrome screening be detected during pregnancy?

Patient's question:

It took a lot of effort to get pregnant, and now I'm over ten weeks along. Today, when I went to the hospital for a prenatal check-up, the doctor said I needed to have a Down syndrome screening. I want to ask if Down syndrome can be detected during prenatal testing? What kind of help I need: Can Down syndrome be detected during prenatal testing?

Doctor's answer:

Down syndrome can be carefully examined, generally based on chromosomal testing. According to your situation, if you are not reassured, it is recommended to undergo further amniocentesis at 16-18 weeks (this is the most accurate) or non-invasive DNA testing (non-invasive is more accurate than Down syndrome screening, slightly less accurate than amniocentesis). The above is the advice for the question "Can Down syndrome be detected during prenatal testing?", hoping it helps you. Wishing you health!
