Patient's question:
My wife is pregnant. A few days ago, she had a detailed Down syndrome screening test at the hospital. Now we have the report, but neither of us can understand it. I'd like to ask how to read the Down syndrome screening report for the fetus during pregnancy? Which specific indicators should be checked?Doctor's answer:
If your wife is currently about four months pregnant and has undergone a Down syndrome screening, the result report mainly focuses on the values of trisomy 21 and trisomy 18. Both of these values have reference ranges. The normal value for trisomy 18 is 1:270, and the trisomy 18 value is 1:350. If it is lower than this value, it indicates a high-risk result. If it falls between this value and 1:1000, it is a borderline risk value. If it is below 1000, it is considered a low-risk result. It is recommended that you consult a professional doctor.
