2nd Trimester

Nuchal Translucency

Good morning! 2 weeks from today I am going to the doc to get a Nuchal Translucency Ultrasound. I'm not quite sure why she is doing this seeing as I am 24, in good health and downs does not run in mine or my husbands family. I know that the ultrasound also tests for other disorders, but I am really nervous. What if it comes back positive and I have to worry about this for the rest of the pregnancy? I mean, it will not change the outcome. My husband and I do not believe in abortion so that is never an option. I also have to worry about the fact that I drank quite a bit during my 3rd week of pregnancy. So, I have that in the back of my mind. All of the worry that I harmed my unborn child. Does anyone have any experience with this? What do you think about the test? Were you happy you got it? Just need opinions and suggestions. Thanks!

  • I've heard there are a lot of false positives with this test. I had a false positive and it sucked, days of worry over nothing in the end. I wouldn't do it again if I had the choice. The good thing about getting and and finding out there is something wrong is that you have a lot of time to prepare yourself.

  • Disease and genetics doesn't care about age. I had the NT scan done when I was pregnant with DD#1 and I was only 21. Also did it when I had DS (I was 22) and did with this pregnancy. (I'm 24). I think most doctors recommend the NT scan.

  • A NT scan is optional, so if you really don't want it, you don't have to have it.  As for the drinking...my OB told me that people do a lot of crazy things in the first few weeks of pregnancy, because they don't know they are pregnant, and babies are born healthy all the time.  I wouldn't stress that one too much.  Plus that wouldn't show up on an NT scan.  As for the results...I wouldn't stress yourself too much.  If you are at low risk, that is on your side.  If, by chance, something comes up, they can do further testing to rule things out, and sometimes early indicators are ruled out by the a/s mid pregnancy.  I had the test done.  Results were fine.  I was happy we had it, but we had family suggest against it, because of the fact that sometimes you get false positive results.  Again, if it doesn't matter to you, and it won't change anything..you don't HAVE to get it done.  It's optional.  Good Luck!

  • I had an NT Scan done. Actually the sono pic in my sig is from the scan. We were scared too (who isn't when you start thinking of "what ifs") but it ended up being kind of fun. You get to see your little one and take a peek at how he/she is doing in there. We got to see all of baby's organ systems, saw him moving and stretching and sucking his thumb, we even got an early guess as to the gender. I am 29 and had no risk factors either. We had the test so we could mentally prepare either way and then just relax the rest of this pregnancy. 

    FWIW our test went well. NT measurement was good, and risk factor for DS and Trisomy was 1:10000. Now we won't have nagging worries in the back of our minds until LO is born.

    The NT Scan is not a "positive" or "negative" test. It tells you if your little one is at risk for disease. If they feel your baby is at risk you'll have additional tests (amnio or CVS) to find out for sure. The NT is an OPTIONAL test. If you don't feel comfortable with it you can cancel your appointment and tell your OB.

    For us, we're glad we did it. But if you don't feel it's right for you, just opt out!

    Good luck! :)

  • We took every test offered to us with both babies. We wanted as much information as possible. We just got the results back yesterday and they gave us a risk of less than 1:10,000, so it was nice to have that information and have one less thing to worry about.

    Like PP said, it's not a 'positive' or 'negative' test - it's a screening test that compiles risk factors and information to give you an overall risk of certain genetic disorders. It cannot tell you 100% yes or no, your baby does or does not have this disorder. Then based on that, you can opt for further testing like an amnio that will give you a definitive yes/no answer (i.e. a 100% certain diagnosis). So, if that test gives you a negative result, you can relax and not worry about it for the rest of your pregnancy. If it gives you a positive, then you have some time to prepare before the baby is here so you're not hit with 'omg my child has down (or worse)' at the moment of birth.

     

    Incidentally, at 3 weeks, before you know you're pregnant, the baby doesn't even share your blood source yet, so drinking heavily at that point won't harm it. So you can rest easy about that.

  • Thank you, everyone! All of your posts have put my mind at ease. I greatly appreciate it. My husband and I have talked about it and are definitely going to follow through with it.
  • DOWN SYNDROME IS NOT GENETIC!  It doesn't "run in the family."  There is a small transmutation that is genetic, but it accounts for such a small percentage of Down cases, it's really not even counted.

    Please be informed about things like this.  People always say "well, it doesn't run in my family."  No because it can't "run in families."

  • 40% of babies with an increase NT have a heart problem. It would be worth it to me to know if my baby had a heart problem so we could make the preparation to have it fixed sooner than later.

  • It's your personal choice. I do believe that a lot of these tests these days are designed to cause more tests and therefore generate more money. Just my opinion. I had an increased NT scan. Normal is 2.5 and the babies was 2.7. I was recommened and AMNIO several times even though my risk of miscarriage with the amnio is higher than my risk in downs. 1:941 So instead, I have had to have a fetal echo and another ultrasound at 28 weeks. All this has caused me nothing but worry. My fetal echo came out fine but they are still doing another Ultrasound. I'm still in constant worry, I just don't believe in these tests.
