The results of the non-invasive prenatal DNA report card are usually low risk or high risk, and the screening rate of non-invasive prenatal DNA is over 99%. If the result is low risk, the chance of the fetus having Down syndrome, which is trisomy 21, trisomy 18 and trisomy 13, is very low, almost none, and the expectant mother can continue to have regular labor tests. If the non-invasive prenatal DNA screening result is high risk, the fetus is at high risk of having Down syndrome and can be identified as a child with Down’s syndrome, and amniocentesis is required to confirm the diagnosis. Since Down’s syndrome is a chromosomal abnormality, there is no cure for it. When Down’s syndrome is diagnosed, it is best to terminate the pregnancy by inducing labor.
