An early Christmas gift

I received an early Christmas gift today, no not a Red Ryder BB Gun.

Last week I posted “Houston, we have nasal bones” with details on my NT ultrasound and first trimester screening test. The genetic counselor from my maternal-fetal medical specialist gave me a call.  The results are in!  We received good news that the results are normal and show a decreased chance of trisomy 13/18/21.

I understand that these are screening tests and not diagnostic tests, but they do allow me to breathe easier for the next month or so before we will get amnio test and results.   

Here’s what we’ve got.  The genetic counselor started with Trisomy 21 (Down syndrome).  Given my age, the normal statistics for a child with Down syndrome is 1 in 62, or a 1.61% chance.  After the screening results, that number is now 1 in 627 for Baby A (.15%) and 1 in 660 for Baby B (.15%).  Going from roughly a one-and-a-half-percent chance to one-tenth-of-a-percent chance is very heartening indeed.  I was pretty happy about that.

For trisomy 13 and trisomy 18 she said the normal listed risk at my age was 1 in 109 or .9% to 1 in 2161 (.04%) for both Baby A and B.  Again this is very good news. 

I feel right now like one of my very favorite Christmas songs…

I am merry, my heart is light.  Big hugs and much love –- Traci.

Great news!

Warning: Assvice follows.
Just a thought - are you sure you want to do amnio? I don't want to be a pain if you've thought it all through already, but even though I'm 35, I decided that if my NT and nasal bones looked good, I wasn't going to take the 0.5% risk of miscarriage that comes with the amnio. Your results so far sound very good (and I'd think the fantastic NT scans might be the more accurate part of that with it being multiples?), and if I were in your shoes, I think I'd probably want to leave well enough alone.
Trisomy 13 and 18 aren't very compatible with life (only 5-10% survive the first year, and I'd bet that's with lots of medical intervention for most). If one child were to be affected, given the severity of the condition, you could most likely opt for comfort measures only in terms of their care.
Before doing the amnio, you need to be sure you know what, if anything you'd do with bad news if you were to get it. Would you consider terminating one baby if it had an issue, putting the other at higher risk? Would you be OK raising a child with Down syndrome? Are you only doing the amnio for added peace of mind? Most likely, your anatomy scan at 18-20 weeks will give you even more reassurance that everything's normal, and given how hard you've worked to conceive your monsters, how much risk are you willing to take?
Chances are the genetics counsellor will have already gone over all this with you. But sometimes they don't, and people opt for the invasive testing without knowing all the risks or realizing the implications. If you wouldn't terminate for one of the conditions, there's not much point in going ahead, if you know what I mean.
Hope that wasn't too long-winded and annoying! All I want to do is provide food for thought, so please don't take this as criticism of your plans/choices. Last thing I want to be is judgemental, since I know everyone's comfort level with stuff is different.

Yay - that is great! I wonder how they split up the odds - they just gave me one number for both of mine?
