Invasive vs. Not invasive genetic testing

The way it was explained to me is that the initial non-invasive testing will tell you whether or not you should look into more invasive testing and then those tests can allow you to treat the baby for fixable issues before they are even born. I fully intend to do the inital testing as they can detect those issues or prepare you for life with a baby with something that cannot be fixed like Chromosomal abnormalities.

Luckily my doctors office offers the initial non-invasive test to all moms to be regardless of age! 🙂

@ANewMrs:  I had the Jewish panel done (blood work) and the NT scan (u/s with blood work).  I believe most conservative providers would start with the uninvasive tests and only move to more invasive procedures (amnio, CVS) if they felt it was necessary based on the results of the noninvasives.  It’s really ultimately up to you what tests you want to have done, though regardless of your age.  

They also have blood tests (MaterniT21, Harmony, Panorama, etc.) that are used in place of the traditional 1st trimester screen (NT scan + blood work).

Good luck!

@ANewMrs:  I think they now offer pretty accurate blood tests for Down’s.  My mom was 39 when she was pregnant with my sister and her doctor classified all patients over 35 as “geriatric” pregnancies.  Such an awful term!  He highly recommended chorionic villi or amniocentesis for all mothers 35 and older since the risk for Down’s and other genetic problems are increased.

I highly recommend testing because whether you plan to continue with the pregnancy or not it educates you as to the risks and it allows you to be prepared should the child have special needs.  There are great supports groups and parenting co-ops that you can tap into during the pregnancy for support and guidance (as well as assistance in navigating complicated genetic disorders for medical care, respite care, and funding resources.)

It’s definitely a good idea to be on the same page with your SO before TTC so you have an idea of what path would be best for you as a couple.

P.S. My mom’s (and baby sister’s) tests were fine.  She had no complications from the amnio and we were able to know my little sister’s sex at 12 weeks because we had her DNA panel.

@ANewMrs:  I second the idea of doing the new blood test. MaterniT21 and Harmony are the most common ones. It’s a blood sample from mom, taken at 10 weeks or later. You get results in 2 weeks and it is more accurate than the typical genetic screening tests (I think 99% accurate for Downs, 95% for other trisomies, but don’t quote me on that), and is absolutely no risk to baby. Plus, if you want, you can find out the sex too. I did the Harmony test and am very happy I did! If you’re over 35, your insurance should cover it.

There are several tests prior to something as invasive as an Amnio or CVS. After blood work and a NT, on a subsequent U/S they found my baby had a somewhat “bright bowel” which could be an indicator for Down’s. I did a blood test (CCCH? CCCP? not sure, they called it the “new test”) and eliminated the odds of DS by 99.9%.

I had the Verifi test done – that is the one we have available in Canada. I was happy with it, its like the Materniti21 test. Results were quick and accurate. I did at 13 weeks and also found gender. I opted out of the NT scan because it is not as accurate as the blood test and I didn’t want too many ultrasounds during my pregnancy.
