Patient's question:

Doctor's answer:

Medical Analysis: Hello! You are pregnant. The hospital performed a Down syndrome screening, and the results showed high risk. In this case, further testing is required because if a Down syndrome child is born, there is no treatment available, which would become a heavy burden for the family.
Recommendation: With a high risk of Down syndrome screening, the most common test performed now is amniocentesis, which can determine whether the fetus is a Down syndrome child. If it is not a Down syndrome child, you can continue the pregnancy. If it is confirmed to be a Down syndrome child, it is recommended to terminate the pregnancy.
