rusty really try not to worry. The 1 in 10,000 result is the standard Harmony or Panama "low" result. The alternative is 1 in 2 or 1 in 3. There is no inbetween - hence why it is a preferred measuring tool.
1 in 250 and below are the results which usually trigger a decision to have further testing on the standard nuchal test. If you google your age, I'm pretty sure your results sounds completely normal. Age is the biggest factor in the calculation. That is why I am disregarding mine and having the Harmony. I personally wouldn't want to have intrusive testing just because of my age. Fingers crossed your second bloods work on the Panama to set your mind at rest. Then you'll too (probably) have a 1 in 10,000 result like your friend.
I agree - impact on existing children is the reason why I would choose to have further testing if I get a higher score.
My first scan is tomorrow (and Harmony bloods). I cannot wait! I can;t believe I've managed to wait it out so long! I had a 7 weeks scan last time and I thought that was a long wait! Really hope all is ok. I've been regularly sick which is not fun, but has set a little part of my mind at rest! Other than that I still have many "did I imagine the whole thing" moments.
