Patient's question:
I heard that the Down syndrome screening can detect fetal abnormalities. I've always been afraid of blood draws, but I can't avoid it. I don't know if the accuracy rate of the Down syndrome screening is high. If it's not, I don't want to do it. I'll just have the 4D ultrasound exam instead.Doctor's answer:
Down syndrome screening is usually completed between the third and fourth months of pregnancy. Down syndrome screening remains a very important test throughout the entire pregnancy process. Therefore, it is recommended to perform Down syndrome screening clinically. The accuracy of this test is relatively high. If the diagnosis indicates a high risk, the fetus may have developmental issues. If the test result is low risk, most risks can be ruled out for fetal abnormalities. I suggest you have the doctor review the results after the test.
