Prenatal genetic testing

Will you be doing any genetic testing? Our midwife gave us info on it yesterday. We have to decide over the next couple weeks because the first blood test is around 10-12 weeks I think? Anyway, she told me that there are a lot of false positives on the blood tests, and that amniocentesis can possibly cause a mc. Frankly I don't think I want to do it for those reasons and also because it will stress me out too much, and it looks like age has a lot to do with risk and I am only 26. So I am leaning towards no right now...what does everyone else think?

Nah, we don't do any of that. The benefits are not worth the risk, for us personally. We would never terminate nor would we ever do an amnio (unless it was a situation where we could save mine or the baby's life). I have heard far too many moms who were told they were in a higher risk category after the testing, then they worried and stressed about it, stressed themselves out wondering if they should do an amnio, etc, etc. And almost always they ended up with healthy babies. So I just don't see the point of the testing (for me).

I will get the testing done. It is covered by my insurance so it is no cost to me. I would rather know something is wrong earlier on so I can be prepared and do research on it than be shocked at birth. I wouldn't terminate unless my life was at risk.

We won't undergo genetic testing either.

We wil probably do the nuchal test or first trimester screen. its done between 11-13w5d or something like that. its an u/s which measures the babys parts specifically the neck folds with a blood test to screen the baby for downs and trisomy something and its better as far as less false positives than the quad screen around 16 weeks. I wouldnt do the amnio unless the nuchal screen show increased risk.

For us we would want to be prepared if the baby had downs or trisomy conditions.

The risk of miscarriage from amnio has gone down in recent years due to experience i suppose. It used to be about 1-2% but now its about half that.

Yeah....I am leaning more and more towards no. It's all covered under our provincial health care so no cost, but I think still not worth it. I was told it would be one blood test in a couple weeks, then one more in another two weeks or so, and then if those two blood tests showed a higher chance, it would be right on to amniocentesis. Maybe the ultrasound too, I forget. I don't think I could handle all that waiting and wondering. Especially with so many false positives. So much to think about, I guess!

It is alot to worry about! As if we didn't have enough concerns already. LOL

did they offer the nuchal scrren or first trimester screen?

I dont know what test they do at 10-12 weeks and again later. I only know about the Quad screen (notorious for false positives) and triple screen or AFP for blood draws.

Not sure if this is the same as what you're talking about, but I just took a look at my handout. Looks like it's two blood screening tests, one between 10 and just under 14 weeks, and the second between 15 and just under 21 weeks. If those screens show an elevated risk, I'd be offered a NT ultrasound and amniocentesis, depending on which of the conditions I'm at risk for. 1 in 20 women will show a positive screen, though something like only 1 of those women will actually be positive!! So false positives (and then the worry) is a concern for me.

We have never done any genetic screening in our prior 2 pregnancies and I feel that not doing it is the right choice for us. Good luck with your decision, Hilary.

I definitely won't have any unneccesary testing done. My doc sends me for blookwork during the first trimester, once in the second, and then once more for gestational diabetes. I agree that so many times they come out with false positives and cause a lot of worry and stress for nothing. With my last baby they screwed up my testing and because they were unaware that my US tech had pushed my due date back 6 days the test showed that my daughter was at an increased risk for downs. It took them a couple of days to figure out where they had screwed up and I was devastated during that time... all that worry for nothing. It wouldn't matter to me anyway, I would never terminate the pregnancy either way.
