Patient's question:
Down syndrome screening risk value for 21-trisomy is 1/300 at critical risk. Is amniocentesis necessary? How great is the impact on the fetus?Doctor's answer:
Analysis of the condition: Based on your description, your situation is that the results of the Down syndrome screening are in the critical range. In such cases, an amniocentesis should be performed to rule out fetal chromosomal abnormalities.Recommendations: Generally, a normal Down syndrome screening result is less than 1/2500. Your result is relatively high, so an amniocentesis is necessary. If the amniocentesis results are normal, you can continue the pregnancy with peace of mind. If there are any issues, it is best to terminate the pregnancy. Additionally, this test is performed under ultrasound guidance and will not affect the fetus.
