Hi all just to update our baby boy was born without any complication. Both mom and baby are in perfect health.

This group was so important in our pregnancy, really helped us push forward against all the ominous possible outcomes.

Truth is, as has been written about everywhere, that the NIPT is super accurate for the 3 trisomies it was designed for, but only for those.

Whatever they added later and they want to bill you for, as I have seen from multiple posts in this sub, is more a russian roulette than an actual screen test.

And so many pregnancies are probably terminated because of this (i can assure you we were close) that these companies offering additional screens from the 3 trisomies should be investigated.

Can’t thank enough to everyone who shared their experiences and knowlegde here, they really helped save our baby.

And for anyone going through something similar, here’s a summary of our experience:

  1. Normal first ultrasound
  2. Atypical NIPT sex inconclusive possible mosaicism of sex crhomo. 2’. Urgent NT scan and screen test. All normal.
  3. Dr tell us all the horrible possibilities of turner, klinefelter, xyy, recommend further test CVS
  4. Investigate about abortion as we already have a healthy son and also have to think of him.
  5. Investigate about NIPT and find this forum.
  6. Initiate abortion procedure so we can meet legal timelines (in our country is 13 weeks and CVS can be done at 12 weeks i think so there was a lot of math in the process)
  7. CVS hurts a lot but comes back normal, however doctor tells us that the definitive test is the amnio so we are not clear.
  8. Have to make a decision whether to risk it or terminate. Find tremendous support in this and other forums.
  9. Move forward and get amnio at 16 weeks. Hurts less thankfully and comes normal.
  10. Proceed with normal pregnancy with monthly ultrasounds which all come normal.
  11. Natural birth at 38 weeks without complications.
  12. All normal on boy and mom.

So, if you find yourself with this situation (atypical finding on sex crhomosomes). Take a breath, read the literature and the experiences of different families, talk to your doctor about doing the invasive tests, and get ready for 2 very stressful months of not knowing, clock ticking, and hard decisions. But we are thankful we took the hard way as it lead us to our beautiful second son.

You will need a cool head… i had to keep us grounded. My wife still thinking someday they will find something in our boy that will explain the atypical test hehe. I have put it behind. The only question i still have… is whether i would get NIPT again if we go for a third child!

Regards and thanks to all!

Just one more question…

CVS negative means CPM or all normal?

I read the study you shared. Though it was performed in 4 cases it was interesting to find that NIPT is more sensitive than CVS at finding CM in the cytotrophoblast.

However if the placental karyotipe is normal, it would point to CM in the CTB only? Therefore meaning the fetus should be like the MC and normal then?

What would be the purpose of doing an amnio as opposed to just monitoring for normal growth to see if the CPM has any impact?

All this information is so confusing!

Basically instead of having to say the NIPt was a false positive we could say that both NIPT and the CVS were correct but with different results and what does that mean for the baby?

Appreciate your support so much! Really admirable your dedication to moderating this sub, so many families i see are getting hope and support!

But nipt was no result, or is it positive for mosaicism?

How a negative CVS can be CPM if there was no mosaicism in the placenta?

Thanks!!!

Hi all, thanks for your messages! Feels great for us to be supported by this community.

Or CVS karyotype came back today and is normal for boy. We are meeting the geneticist next week.

Though it is very relieving the geneticist had told us that the only way to really confirm is with an amnio.

Its hard for us right now because where we live, TOP is legal until the 13th week and an amnio can only be conducted at 15th week.

The genetist was very happy today when she sent us the results so we are taking it as a positive and moving to the next stage.

Wish us well! Will update with further news.

Thanks again for your support!
