First Trimester Screen results

Were screen negative!?

They gave me a less than 2 percent chance of having down syndrome. The genetic counselor said these were reassuring results. My chances based on age alone had been greater than 2 percent. (However, the test only flags 85 percent of down syndrome cases, they estimate)

I have to make a decision by Monday now on the CVS test. ?I'm 40 and I definitely want a diagnostic test, but I can't decide between CVS and the amnio.?

The facility quotes a miscarriage rate of 1 in 300 for CVS.?

Because I've already probably pissed enough people off today, I'll just refer you to the post right ahead of you for my cranky rant on amnio and/or CVS and the whole "need to know" debate.

But do the math.... you're talking about a 98% chance that you're just fine.  If you were in Vegas, you'd be taking that bet.

BrideBuddies, you are not going to piss me off. It takes a lot more than that to do it.?

(The 98 percent chance is correct IF the screen caught all cases which it doesn't). I'm not trying to start a debate. I know the odds are good. The bottom line for me is I want a diagnostic test. I'm just trying to decide which one.

, Bridebuddies!  Your opinion on this doesn't piss me off either, just so you know.  I just have a different point of view.

Different ppl have different opinions on this topic.  It does tend to be a pretty touchy topic.  DH and I opted for the CVS for reasons I have already posted in the past week, so I won't state them again.  We got our results back yesterday -- we now know with 99.9% accuracy that our baby does not have chromosome abnormalities, at least with regards to the chromosomes examined.  I saw the baby two days ago on U/S.  She looks great, her HB is 164 bpm, and she was moving around and being very active.  We are happy we did the CVS and got a diagnosis, not just risk numbers.  But, that was our personal decision.  

Before we made our decision to do CVS, our genetic counselor asked what risk numbers would I be happy with if we do the NT screening.  I said 1/500.  But, when she told us that the NT screens only 75% of possible abnormalities, we didn't want to leave 25% unknown b/c I have a family history of Down's.  That, coupled with a negligible chance of m/c, made the decision for us. 

If you think you will worry throughout your PG about this issue, then go for the CVS.  It was a very easy and safe procedure for me.  Just my two cents!

I'm sorry, I must have overlooked your real question, which is CVS v. amnio.  At my dr's office, the risk of m/c for a CVS are the same as that for amnio -- TINY (my dr is really good!).  DH and I are not exactly the most patient ppl -- we wanted to know sooner than later.  So, since there was no increased risk, the CVS was the way to go for us.

In our case, CVS wasn't an option because of the location of the placenta -  they couldn't really get to it for the CVS. At the office we used the CVS statistics were about the same, it was just a matter of timing. We were glad we did it.

I just wanted to say congratulations on your numbers.  We had really good numbers as well and decided not to do CVS or Amnio.  Good luck with whatever you decide.
