For the uninitiated, this is how they do it: They assign odds of having a baby with Trisomy 21 or 18 based on your age. This is your statistical risk. This is then adjusted based on the NT value, and beta HCG and PAPP-A levels.
My calculated or statistical risk for Downs was 1:536.
After adjusting, my risk was a very comfortable 1:8,000 +
For Trisomy 18, my adjusted risk was 1:100,000 (!)
YAY!!
Even a worry-wart such as myself would relax a bit at this point. But I can never go all the way it seems. J told me this morning that her nausea was dying down....and instead of celebrating, I started getting slightly worried. That is INSANE. Of course her nausea is supposed to go away at this point, but try telling my hand-wringey stupid self that.
I've run into a bit of a roadblock trying to find the Indian partner for BGI (the Chinese company) to run the fetal DNA testing. While I'm more relaxed about the 3 big ones now (13, 18, 21), and also to an extent, Turners (it presents with an increased NT thickness and lower PAPP-a levels), I would also like to get the other sex chromosome aneuploidies (Kleinfelters and triple X) ruled out, and they can't really be detected by ultrasound. BGI, according to one link, may be able to do this.
Science aside, I'm thinking about this baby constantly. The advice my parents gave me (don't think about this one way or the other) has fallen by the wayside. I'm so scared about how many things still have to go right for this baby to make an appearance safe and sound. When other people with losses had gotten to this point with everything looking good, I had relaxed and thought their chances were great. On paper, I know things look good. If only I could believe it without reservation now.
