Patient's question:
At 17 weeks of pregnancy, the two screening tests for the TNI screening showed low risk, and one test showed a critical risk of trisomy 21 syndrome at a 1/890 probability. Is it still necessary to do it?Doctor's answer:
Based on your description, I recommend non-invasive DNA testing. The diagnostic rate of Down syndrome screening is 50%-60%, the diagnostic rate of non-invasive DNA testing is 99%, and the diagnostic rate of amniocentesis is 100%. You can choose for yourself. I don't know what the doctor will advise you after the test. I suggest getting tested for one to be safer. Currently, the diet during pregnancy is relatively light. Avoid spicy foods.
