My CVS is scheduled for Wed. 10/20.
I opted for an amnio w/my first DD because I had a 3rd cousin who had DS.
Renee, 43, EDD 03/05/11
I don't want to find out the gender as I'd love the surprise after giving birth "it's a...." but my husband is also planner and wants to find out.
I had CVS with both my first pregnancy at 39 and this one at 42. I was very glad to be able to get a test at 11 weeks rather than waiting until the second trimester. CVS is done by a specialist, so they tend to be experienced. I planned to have the test from the start, and appreciated having that option, as it can test for precisely the type of chromosomal abnormalities that age puts us at a higher risk for.
I found the physical discomfort to be fairly minor, especially compared with nearly constant nausea that I had for three months; the needle part takes a few minutes, and is likely similar to amnio (I never had one). Two days later they called with preliminary results, which are 95% accurate (fortunately, good news both times) and the gender (second boy; I will be surrounded). Full results come about two weeks after the test.
For me it's the waiting for the results part that is the hardest.
My EDD is 11/24/10; I will be 42 1/2. I am in NYC, where having a baby in your forties is not unusual. When I told my OB that I was bummed about not having a girl, she said, well, try again.
It may be that the lab does not do the preliminary test, but if they do it, you should be able to get results. I would be surprised if Standford does not do it.
BTW, for 3 days after the test, they tell you not lift your kids and to take it easy. My husband had to do all the diaper changes. After the test they tell you to go home and rest (I was tempted to cheat and go to the office, but thought it would not be worth the risk or the guilt).
My OB is actually very supportive and doesn't seem to think I'm too old.
