Patient's question:
During the prenatal check-up last week, I was found to have a high risk of Down syndrome screening. The doctor said it might be necessary to have an amniocentesis, but it is said that this procedure involves an incision. I would like to ask, what does a high risk of Down syndrome screening mean? Is it necessary to have an amniocentesis?Doctor's answer:
Down syndrome screening high-risk indicates a higher risk of the fetus having Down syndrome. After a high-risk result from Down syndrome screening during prenatal care, the pregnant woman does not necessarily need to undergo amniocentesis. Non-invasive DNA testing is also an option. Non-invasive DNA testing has an accuracy rate of 99.99%; amniocentesis has an accuracy rate of 100%. Decide based on your personal situation. If you are concerned about psychological trauma, you can choose non-invasive DNA testing; if you want a 100% accuracy rate, you should choose amniocentesis.
