What should I do if I have a high risk of Down's syndrome during pregnancy?

I have been pregnant for a while, and I went to the hospital for a Down's syndrome test. The doctor said it was high risk. What should I do if I have a high risk of Down's syndrome during the pregnancy test?

Pregnant women who are found to be at high risk of Down's syndrome during pregnancy need further examinations, such as amniocentesis, to directly observe the number and structure of fetal cell chromosomes, or choose to do non-invasive DNA examinations, which can Clearly understand the risk of the fetus suffering from trisomy 21, trisomy 18 and open neural tube defects. If the test results indicate that the fetus with Down's syndrome is at great risk, the pregnancy can be terminated in time under the advice of a doctor if necessary, and the birth of a Down's child can be avoided. If the test results show that the fetus is less likely to have neural tube defects, the pregnant woman can continue the pregnancy.
