I'm so glad that you are getting great support already from your previous practice. It's great that you have the option to meet with the genetic counselor even if you decide not to do the CVS.
I had the nuchal translucency screeing (ultrasound and blood test) at age 42 so I always knew based on my age alone that my risk would come back higher, but I did not expect a 1/5 chance for Down Syndrome and a 1/23 chance for Trisomy. I had passed the window for a CVS and had to wait for the amnio. It was a horrible, horrible time. I'll cut to the chase and say that DD2 is now 27 months old and does not have Down Syndrome or other issues. She's a peanut but feisty and perfectly healthy and happy.
One of the reasons that the wait was so hard was I googled (bad, I know) and learned that the blood test done with the NTS can yield information about other adverse pregnancy outcomes beyond chromosomal adnormailities. I didn't know that. I thought that if the CVS/ammnio came back fine then everything would be fine. There's early evidence that shows the low beta-hCG, low PAPP-A, can signal risks for IUGR and other things. That threw me for a loop.
The visit with the genetic counselor before the ammnio was a very good experience. She explained what I had googled and went through the blood test results and explained why even though my risk was 1/23 it was unlikely that the baby had Trisomy. The focus really was on DS. I'm very glad that we had the amnio based on the conversation with the genetic counselor alone. The genetics department let the midwife practice know that they should be on the lookout for IUGR based on my blood test. Without that prompt from genetics, I know they wouldn't have scheduled the extra ultrasounds to screen for IUGR. Sure enough, an ultrasound at 37 weeks pointed to IUGR so I delivered that day. She did have IUGR and weighed only 4 lbs 6 oz at 37 weeks 4 days. I'm forever grateful that everyone was paying close attention.
I say this not to scare you but to confirm that it sounds like you are with a practice that will have everything covered and that the meeting with the genetic counselor will be really helpful.
