Question
The risk value for the 21-trisomy screening is 1:530, indicating a low risk. However, the risk value is close to the critical threshold of 1:270. Should I undergo amniocentesis?
Answer
According to the 21-trisomy screening results, the risk value is 1:530, which falls within the low-risk range, but is close to the critical threshold of 1:270. Due to the proximity of the risk value to the threshold, doctors suggest performing an amniocentesis to further confirm whether the fetus has chromosomal abnormalities. Amniocentesis can provide a more accurate risk assessment and help rule out or confirm trisomy 21. It is recommended to follow the doctor’s professional advice and undergo an amniocentesis.
