What is the probability of a fetus with Down syndrome being born healthy?

Patient's question:

Down syndrome screening result: Trisomy 21 is 1 in 207, which is high risk

Doctor's answer:

Analysis of the condition: A high risk result in the Down syndrome screening indicates a higher likelihood of giving birth to a child with Down syndrome. Children with Down syndrome have severe intellectual disabilities, cannot live independently, and are often accompanied by complex cardiovascular diseases, requiring long-term care from family members. This can impose significant mental and financial burdens on the family.
Recommendations: It is recommended to undergo amniocentesis and fetal chromosome testing between weeks 16-20 to confirm whether the child has Down syndrome.
