43 years old, 20 weeks pregnant, Down syndrome: 1:155 is it high risk?

Patient's question:

No

Doctor's answer:

Down syndrome children have severe intellectual disabilities, cannot take care of themselves, and are accompanied by complex cardiovascular diseases. Down syndrome screening indicates high risk, suggesting a high possibility of giving birth to a Down syndrome child. It is necessary to perform amniocentesis and fetal chromosome testing to determine whether it is a Down syndrome child.
