    Default Bad NT score from blood test

    Hi, Just wondering if anyone else has had a good NT score via ultrasound but bad score from Blood work?

    I had my NT scan bloods Monday and NT scan yesterday (wednesday) Dr just called to say that i have a 1 in 33 chance of DS. The scan results were alright but the bloods was the one which gave me that score.

    I am having issues finding information from the blood work side of things. Can you help me or share your stories.

    Thanks in advance..

    Hi darl.

    I had the same issue. My scan was fine but the blood test resulted in my risk increasing to 1:41. Mine was due to low Papp A. Is that what yours was?

    From what I was told, the low Papp a levels are more often than not due to placenta issues, but of course it also raises concern with the chromosome tests too. I had an amnio and it turns out everything is fine. Chromosome wise. So that just means I'll require more monitoring toward the end regarding the growth of the baby.

    Do you know if you are going to have an amnio or anything?

    Just remember though, 1:33 might sound bad, but try look at it as a percentage. Mine was a 2% chance. Doesn't sound so daunting when you put it that way hey. Try not to stress Hun xoxo

    I am not sure of the Papp A. (what is Papp A??) The dr just told me the score and i didn't know (and couldn't think) of any questions to ask..

    I will be having the Amnio test to find out (not that it will change my mind but would like to prepare before birth)

    Hi,

    For my last pregnancy I also had a high risk (1:21) based on the blood test results alone, the NT scan was normal.

    We chose to have CVS testing which showed no chromosomal abnormalities. I was also further told there may have been placental issues because of low Papp-A levels but in the end there were no problems and DS is now a healthy 2.5 month old.

    Hope all goes well for you.

    I had this problem too, ultrasound measurement was excellent but bloods were really bad! My Papp-a was only 0.07 and it is meant to be around 1.0. I had cvs done (2 weeks ago) and got results yesterday. They had to test for every known chromosome problem. I had a 1:3 of downs, 1:55 trisomy 18 and 1:108 for trisomy 13. Test came back that everything is completely normal. They now know my placenta is the issue.

    You will more than likely be ok, but to put your mind at ease, have a cvs or amnio done. Get it done by a dr that performs these everyday to eliminate the possibility of miscarriage.

    Hope all is ok xx

    I had a normal NT result (High end of normal though), and my blood results gave me a 1:20 risk of T21.

    DS did not have T21.

    Hi
    I'm not due to have my NT scan until march 29 but the results r something I eagerly await. What is the difference between CVS and amino tests? Is the amino one when they put a needle in your stomach through to the womb? Do any hurt?
    Good luck to everyone!

    Cvs is usually done between 11 and 14 weeks and they insert a needle either through your stomach or through your cervix (?) to take samples off your placenta for testing. Amnio goes through your stomach and takes sample of amniotic fluid. Both are tested for same things, however, you get your results earlier if you have cvs because they don't do amnio's until about 16-20 weeks.
    In my opinion, I had a cvs and it bloody hurt a lot. Not the needle into my stomach but once it hit the cervix and dr was scraping for fibers of placenta, that hurt like crazy. I didn't cry then and there but as soon as I left I broke down in tears. Many people say it doesn't hurt, so it may just depend on your level of pain tolerance... I have none!
    The results are I think 99.9% accurate. Having cvs that comes back abnormal gives you a chance to terminate if that's what u want at an earlier stage in pregnancy then amnio does. There is a higher rate of miscarriage in cvs, however, I think as long as you see a specialist who performs these daily, you are in the best hands and your odds go down significantly.

    Hope this helps
