My dr today recommended that I get a nuchal translucency sonogram at 12 wks (2 weeks from now) as well as the blood tests for plasma protein-A (PAPP-A) and human chorionic gonadotropin (hCG). My husband and I don't have any history of Down Syndrome in our family but I am high risk for fetal cardiac issues due to my blood clotting disorder, so the dr was saying that I should have the scan in case there are any signs of cardiac problems. He did acknowledge that he tends toward the medical side and that my midwives will likely advise me to skip these screenings.<br><br>
Is the main concern with these tests false positives, which can lead to further testing and (hopefully) unnecessary anxiety while waiting for results? Or is there any actual danger to the fetus in having a 12 week sonogram? I'm already due for quite a few sonograms b/c I am high risk, so I am hesitant to add another one to the calendar. If I don't do the NT screening, then my next sono will be at 19 weeks, and then I'm supposed to have one a month(!)

The general medical consensus is that ultrasound poses no risks to the fetus. Of course, there are people here who disagree with that. I am having the 12-week scan due to a history of trisomy 18 and the ONLY anxiety I feel about it has to do with possible bad results. I do not personally feel that the fetus is at any risk at all.

What a tough decision! The only thing I would add is that my aunt just went through a very difficult experience that reminded me about the risk of false positives. She is older, and decided to do the NT screening. The screening indicated an issue with the baby's neck- initially it was thought that there was excessive tissue there- and the first diagnosis was Turner's syndrome. This lead to a myriad of additional testing, a horribly stressful preganancy, and a c-section due to concerns that the baby had (additionally) a uterine growth restriction and a high risk of further complications. Turns out the baby is absolutely fine, there is NO excess tissue, everything is normal. Thank goodness for all that, but my poor aunt feels cheated- her whole pregnancy was one stressful event after another. Additionally, she's now in the hospital with four blood clots- the result of her c-section.<br><br>
That's just a personal anticdote, but I know that for many mamas a false positive can be truly a horrible experience. A positive (real or not) can cause a stream of intervention. In the end, though, you have to do what your heart tells you.

NT is usually checked during an ultrasound, and if there is any problem, they usually track in another US. We've always had it mentioned during our US, but we've never had any problems either.<br><br>
Good luck...hope all works out well.

Not necessarily true. I've never had NT checked- in my experience, you are asked, and you can decline.

They might not write it down, but it's not a big deal to measure. Most clinicians will automatically spec it out, and then ask if you want to know. It takes less than two minutes.<br><br>
Mama, don't worry about it. If it was positive, what would it change in your care? You'd probably have it repeated over time to see if any cardio issues are developing. If you're already at risk, i would keep track. That's my opinion, of course.

Thanks everyone for the advice! I've decided to have the screening because of the possible cardiac issues...

We've decided to do it as well-- I'm 37 and expecting twins, and this seems rather non-invasive.<br><br>
ETA: It's not that it would change my mind about having the babies or anything, but since insurance covers it I feel like it would be really good to know in case there was either something that could be done to help them either in utero or as soon as they would be born.

I will only be 26 when this baby is born and I am pretty sure my ins co. won't pay for it.<br><br>
I will have the anatomy screen at 20weeks though <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/smile.gif" style="border:0px solid;" title="smile">
