Patient's question:
Is a 1/160 result normal for the Down syndrome screening?Doctor's answer:
Analysis of the condition: A 1:290 risk ratio indicates a high risk, requiring further amniocentesis to determine if the child has any issues. Because prenatal screening is only a screening test, a high-risk result may still be normal after amniocentesis. Prenatal screening can detect 60% to 70% of Down syndrome cases.Recommendations: It is generally believed that amniocentesis will not harm the fetus, as all procedures are performed under strict ultrasound monitoring, allowing clear visualization of the fetus's position. Therefore, there is no need to worry about the needle causing harm to the fetus. Amniocentesis is typically suitable for pregnant women around 16-20 weeks.
