Hi everyone,
Just had the results back from my 12 week NHS screening and it's said baby has a 1 in 10 risk of Downs syndrome. This has come as quite a shock to say the least. I'll be 33 at term, and having done a bit of research into my results (bHCG 1.88 MoM, NT 2.9mm, Papp-A 0.72) I don't think they are that extreme, so I'm confused where the very high risk has come from. I've read with Downs you often have elevated bHCG but lower Papp-A, but my Papp-A result was much lower with my DS1 who is all healthy (and he had a v low risk result for the 12 week screening). I've also read some papers which seem to say female fetuses can lead to these higher results...surely if that was the case they should account for that?
We've decided to have a CVS test which I'm very anxious if I'm making the right decision about given the risks it holds (I'll be 13w on the day), hoping I can get some clearer answers about the above figures before the test but everyone at the hospital I've asked so far has been pretty useless just saying they've calculated it as high risk.
Wondering if anyone has similar experiences they are willing to share and also the outcomes? I'm trying to stay positive but also can't help but worry. Sorry for the long message but would be very grateful for any responses, xx
