1. How to determine the gender of a baby based on Down syndrome screening results?

First look at the MOM value of b-HCG:

Below 0.4, most of them are boys;

Above 1.0, most of them are girls;

It is close to between 0.4 and 1.0, which is the critical value range, and it is possible for both men and women.

Then, the combined binomial values ​​(b-HCG and AFp) are more accurate:

The lower the b-HCG MOM value (<0.4) and the higher the AFp MOM value (>1), the more likely it is that the baby is a boy.

The higher the MOM value of b-HCG (>0.8) and the lower the MOM value of AFp (<1), the more likely it is a girl.

In addition, in the blood cells of Down syndrome children and Down syndrome positive children, regardless of whether the fetus is a boy or a girl, the b-HCG value is higher, but the AFp value is slightly lower.
