The amnio isn't done until about 15 weeks on, if a doctor performs it too early it makes the risk of miscarriage go up.
your NT was GOOD
and your other numbers are alright as well, not great but ok. I seriously think you should consider a level 2 U/S before an amnio to see if there are any soft markers.
Update:
I went to talk to my OB today and to get a copy of my lab results. He said that the Perinatologist (the only one in the town where I live) won't meet with a patient unless they are at a risk of 1:30 or greater before the results for the 2nd trimester screen have been factored in. This is ridiculous, my doctor said that he would refer me to a larger peri practice in the nearby large city. I got an appointment for Thursday morning.
The results were:
NT 2.2mm 1.29MoM
PAPP-A 0.31 MoM
hCG-1.48 MoM
1:48 for Down Syndrome
1:800 for Trisomy 18
My doctor said to be prepared for an amnio but I think that 13w6d is still too early. What do you think the doctor will do/recommend at this point?
Your NT results were alright. I don't think it is anything to really worry about. these tests are only indicators for your risks, they don't come up positive or negative. and the blood screens are extremely unreliable
I had high results @12.5 weeks with my youngest son. I ended up with abnormal results on my 16 week blood work and ended up being pressured into an Amnio (it was a very short decision) and everything ended up to be completely fine. I would say that the only thing you can do at this point is wait... which is the worst part of pregnancy anyways. I know there are a few more girls on here that have first hand experience with DS and can tell you what exactly the high risks for DS are. I hope that you feel better about it and hopefully it is nothing more than you can handle. (((HUGS)))
