Nuchal Screening
Fri, 06-04-2010 - 9:25pm

I'm so glad I found this site. I'm 40 years old and pregnant for the first time. I'm 11 weeks 5 days and I conceived through IVF. I went for my last visit to the fertility specialist before I get released to my regular OB/GYN and during the ultrasound they measured the baby and the nuchal measurement came back at 3.625, for my age the Dr said they like to see it at 3 or less. According to the technician the baby was at awkward angle but they're referring me to a specialist non the less. I have the appointment with the specialist next Thursday but in the meantime I'm completely obsessing and for the first time since I found out I was pregnant not enjoying being pregnant.

There was no blood test done, that will be done by the specialist but I'm taking no comfort in the data I'm finding on line that there is a high rate of false positives with this screening. Anyone out there going through or been though anything similar?

Any insight would be appreciated.

Sorry that you are stressing about this & not enjoying your pregnancy. But try to relax (easier said than done for sure!).

When I was pregant the first time at 41, I had the 12 week NT scan done at the HR dr. & it came back with a 1 in 20 that the baby would have DS. Well, of course, I freaked out about that. But then I thought this is my baby and it doesn't matter but you still worry no matter what. Although once I converted that to a percentage, I realized it was only a 5% chance that the baby would have DS and that made me feel better. I went through with having an amniocentsis to be sure and he did not have DS.

With this pregnancy, I opted not to do the 12 week NT scan since I knew it would stress me out & with our age, it usually comes out a higher risk in any case. So I decided to just wait and only do the amniocentsis and found out that our little girl was fine.

Yes, there are a lot of false positives out there. I think sometimes the doctors worry about not saying there is a chance just to cover themselves in case it turns out the baby does have a problem.

Anyway, just wait and go see the specialist and then find out your options of testing and decide what is best for you & your baby and then go from there.

Good luck & kup!

I've walked a similar road as you and Michelle.

My nuchal measurement was actually good, but my blood work PAPP-A score was low which gave me a 1:17 chance for Trisomy 21.

I was a mess for several weeks, but have since come to terms with it all. I was referred to a perinatologist, but since Baby Boy's scans all looked good and we refused amnio, there wasn't any other reason to have to continue on with them. So I was released back to my high-risk ob/gyn.

I've had monthly sonos, and now bi-weekly sonos to measure growth (due to gestational diabetes) and he continues to look good. Never showed any of the 10 soft tissue markers they look for on sono.

The only way to know for sure is thru amnio so research and think about it (pray if that's comforting to you too).

Wishing you lots of luck and sending positive thoughts your way!

My baby had a high number for her NT and also had a septated cystic hygroma. We were told she had a 15% chance of being healthy. After a month of waiting (which was awful) I had genetic testing done & the results were normal. I was so happy I chose the amnio. I have a very healthy 13 month old!

I am going to have my nuchal screening june 21. I'll be 12 weeks then. I'm nervous but looking forward to having it down.

I'm 40, unexpectedly pregnant with my third. we are thrilled! i cried at my first ultrasound, still in awe.

I believe being pregnant in our 40s is a special miracle we have to cherish. it is so hard not focus on the doom and gloom reports out there, I'm guilty too. it seems all our lives we've been told a child with

When I had my Nuchal screening done, the technician told us that things looked good. We didn't get final results until the bloodwork was in too (about a week) but she said that she expected us to get a good result based on the u/s.

Hi there,

I got my NT results back today. For trisomy 21, I'm at 1:180 and for trisomy 18 I'm at 1:10,000. I 'm not sure how they can vary so much. She said the doctor did not recommend any invasive testing but to just go ahead with the second part of the bloodwork in two weeks. She said i could expect my numbers for 21 to even look better after the second test.

My confusion is everything I've read online says an abnormal result is anything below 1:250 and doctors recommend the CVS or amnio at that point. But the doctor said more than once that my numbers looked great and not to go any further.

(I'm 40#

What do you think? Would you feel better knowing your risks for DS were 1:180? That number is better than my odds with my age alone.

BTW -- I felt so happy I cried
