Patient's question:
Please help the expert take a look at the result of the Down syndrome screening, which says low risk, but why do I still need to do a B?free-hCG B-mom value: 3.036
AFP mom value: 1.45321
Trisomy risk: 1/520 (standard 1/270)
Trisomy 18 risk: 1/50,000
NTD risk: screening negative
History of treatment and effectiveness: I took medication for maintaining pregnancy in the early stage. Will this have an effect?
What help do I want: What is the B-C check? Are these values normal?
Doctor's answer:
Fetal protective medications have no effect on the embryo and will not affect your test results. Guidelines: The best time for Down syndrome screening is between 14 and 19 weeks of pregnancy. It is a neural tube defect. Three-dimensional and four-dimensional color Doppler ultrasound can diagnose fetal abnormalities between 20 and 24 weeks of pregnancy. Down syndrome is a chromosomal disease. In patients with Down syndrome, there are three chromosomes in their 21st chromosome, one more than the normal number.
