What does low risk mean in the Down syndrome screening?

Patient's question:

AFP: 1.40
HCG: 5.14
The result is low-risk.
This low-risk result refers to which aspect of the fetus being abnormal.
AFP and HCG both represent which part of the fetus.

Doctor's answer:

Analysis of the condition: A low risk result in the Down syndrome screening indicates a low probability of the fetus developing Down syndrome, with a risk rate of less than 1%. This is a normal result.
Advice: AFP stands for alpha-fetoprotein, and HCG stands for human chorionic gonadotropin. It is a substance, not an organ of the fetus.
