Patient's question:
I got married last year. Recently, I've been experiencing lower abdominal pain, especially during my period. I'm very worried it might affect fertility, and I'm also extremely sensitive to cold and coldness. What is the critical risk value for the Down syndrome screening?Doctor's answer:
The screening test provides a risk assessment value. The critical value is generally 1/270; values above this are considered high risk, while those below it are considered low risk. 1/436 is less than 1/270, so it is low risk. However, the accuracy of the screening test is only about 70%, and a low-risk result does not necessarily mean the baby is healthy. Further tests are needed to confirm whether the baby is affected.
