Abnormal NT Scan

I had my NT scan this afternoon and the baby's neck measurement was 4.3. I know 3 or under is considered normal, so I'm going on Thursday for a CVS and more genetic counseling. I'm scared to death! Has anyone else had the NT scan come back abnormal and had a perfectly normal baby? Can anyone share with me their experience? I'm absolutely scared to death and it doens't look like I'll be getting any peace of mind anytime soon

Re: Abnormal NT Scan
My doctor said that coupled with the blood test they are only accurate 92% of the time and they can give false positives. I have heard of so many people who have gotten positives where their babies are perfectly healthy.
Did u get the blood results back as well?
The genetic doctor I saw said that the chances of the blood results coming back abnormal also were relatively high, so his suggestion was to be a little aggressive and do the CVS on Thursday morning. Rather than wait a week for blood results that will likely be abnormal also, since it takes 2 weeks to get results from the CVS we opted to get that done ASAP.
I'm completely freaking out....

im sry. I wish there is something I could say or do. Sending hugs ur way and keeping fingers crossed everything turns out fine.
Okay 1st off--to the PPs: NT Scans do NOT give false positives. They give you your chances of different genetic disorders. Only a amnio or CVS can give you a false or positive result. And they are not usually "inaccurate." More often than not, they are accurate--85% actually.
OP--sorry you are having to deal with this. I do know women who had a high NT measurement and their babies were perfectly healthy. Studies show that high measurements actually turn out fine 5% of the time. GL and please keep us updated.
OP, so sorry to hear this. Yes, I know several women who had an high NT and who went on to have perfectly healthy baby. As Luvmyducks said, and NT is never 'positive', it only shows elevated risks. It is just an indication that further testing is necessary, nothing more or less. I do not know how much of an elevated risk 4,3 mm means, but there's definitely still a chance that your baby is just fine.
Only the amnio and CVS can tell you what's really going on. I hope they'll bring you good nes!
I agree with all of this. Good luck to you. I can understand how scary it must be but hopefully you will have answers soon.

Yes, the NT scan is only an indicator for chromosomal abnormalities. I had mine done at 12 weeks and had a measurement of 3.9mm. We also saw the genetic counselor, which in my opinion scared the crap out of me, who said the chance of my baby having a problem was now 1 in 10. We opted to have the CVS test done that day because as you said the Materni21 test would take 2 weeks and the CVS test took 2 days for results. Those 2 days we had to wait for the results were the most horrible days so far of my life. We already decided that no matter what the results were we would NOT terminate. Friday afternoon at 4:30 the genetic counselor called and said, we were negative for all chromosomal abnormalities. We also were told that our LO is a girl. (A plus of freaking out is you get to know before anyone else due around your EDD that you are either a boy or girl).
Oh BTW, we received a call about a week later saying that the blood test associated with the NT scan came back and our chance of a child with a chromosomal abnormality was now 1:3. (This was wrong because we opted for the diagnostic test). So do not freak out too much, you can PM me if you want to know more details.
We just had our 20-week A/S scan yesterday and everything looks great with our little girl.

We spoke with the genetic counselor again last night, my husband wasn't able to be at the appointment with me because he was on a plane coming home from business. She was nice enought to give me her cell #! Anyway, she broke it down a little more for us, basically we have a 20% chance of there being a chromosome abnormality, a 7-12% chance of it being a structural abnormality, and about a 70% chance of it being nothing at all. She also let us know that 2 weeks for results is worst case, because of our insurance and the lab, we will have some preliminary results in a few days. Hopefully by Wednesday of next week I'll have more info!
I'll keep ya posted! This is such a hard thing to go through, and I really appreciate all the positive thoughts, and supporting words! Hoping and praying we fall into the 70%
Those are great odds! GL! Please keep us posted
