Question
I am 4 months pregnant and found that one indicator in the Down syndrome screening is slightly elevated, but it is considered low risk. How should I handle this?
Answer
At around 4 months of pregnancy, a Down syndrome screening is very necessary as it is a method to detect whether the fetus has neural tube defects. It mainly looks at the values of trisomy 21 and the 18-trisomy issue. As long as two results are proven to be low risk in the screening results, this means that the possibility of neural tube defects can be ruled out through the Down syndrome screening. If we are uncomfortable, we can consider further testing, such as amniocentesis or non-invasive DNA testing.
