Patient's question:
Screening item: Trisomy 21 screening result: Low risk Risk cutoff value: 1:270 Risk value: 1:530 However, the doctor said these two risk values are too close and there is still a risk, suggesting an amniocentesis may be needed. I'm very worried and confused. Should I have an amniocentesis?Doctor's answer:
Disease Analysis: The critical value is 1/275. Values greater than this indicate high risk, while those less than it indicate low risk.Guidance: It is recommended to undergo amniocentesis. Amniocentesis can detect whether there are congenital malformations, congenital metabolic defects, chromosomal abnormal diseases, or sex-linked genetic diseases.
