I am one of the very rare women who has had both CVS and amino IN THE SAME PREGNANCY. I feel like if someone had told me what I am about to tell you that I would have not had to go through 2 invasive tests and stress twice about possible miscarriage. I am writing this hoping it helps someone else who has to make a decision about how much testing to do and what kind.
Basically, we did the first trimester screening tests and while the ultrasound looked perfect, the bloodwork was a little off, add to that my age (35) we were advised to do CVS testing. So we did. Our preliminary results were perfect, but about two weeks after that we got a call with the final results and we had what is called “mosaicism” meaning that most of our cells were normal, but a few were not. In some cases the masaicism is incompatible with life and you need to prepare yourself for that but ours was not that way, ours was something that if our baby had it, it would be totally treatable. There was also a 90% chance that the issue was limited to the placenta and that our baby was 100% fine. It’s like getting an irregular pap smear, where some of the cells are bad, but overall you are fine.
With CVS testing they are taking the cells from your placenta. The placenta is made up of the same cells as your baby but is also an organ with it’s own life, so there is a chance that some of the cells, that have nothing to do with your baby, can be abnormal. We were never told that this was a possibility or that amnio would be more accurate than CVS (in amnio the cells are 100% baby).
So we had amnio. The good news is that our amnio is perfect. If we had just had amnio, we wouldn’t be worried AT ALL and would be elated by all of the normal, healthy cells they found. But since we had CVS, we will now ALWAYS be worried that they could be mosaicism that will present itself and cause health issues in our baby. For our specific case, we pretty much can relax when she starts puberty, so you know, 14, 15 years from now!
I feel like I have been robbed of the chance to watch my child grow normally without worrying. If someone had explain “mosaicism” to us in advance and the chance to get these ambiguous results, we would have just waited for amnio.
I know this is long, so if you are still reading thanks! I just hope that knowing the difference will help someone else if they have to decide what testing to do. Please PM me if you want to know more about the testing, mosaicism, have questions about the procedures themselves, etc. Having had every test you could possibly have in 18 short weeks, I feel like an expert!
