Patient's question:
Screening item: Trisomy 21 screening result: Low risk Risk cutoff value: 1:270 Risk value: 1:530 However, the doctor said that these two risk values are too close and there is still a risk that 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 above it are considered high-risk, while those below it are considered low-risk.Recommendation: It is best to undergo an amniocentesis test. Amniocentesis can detect whether there are congenital malformations, congenital metabolic defects, chromosomal abnormalities, or sex-linked genetic diseases, among others.
