Patient's question:
Trisomy 21 (Down syndrome) risk is at the critical risk level, Trisomy 21 risk value 1:918, is the risk of having Down syndrome high?Doctor's answer:
21-trisomy syndrome, also known as Down syndrome, is a chromosomal abnormality of autosomes. Down syndrome is the most common type of chromosomal disease in children. Screening is conducted based on the levels of AFP and HCG in the pregnant woman's serum, combined with the pregnant woman's age, weight, and gestational age. The critical value is 1/275. High risk is greater than low risk. If high risk is detected, the probability of the fetus representing a child with congenital idiocy is relatively high. It is recommended to undergo further amniocentesis for a definitive diagnosis to ensure fetal health.
