I mentioned the MaterniT21 back in a thread that we had earlier on in our pregnancies, the test that uses fetal DNA present within maternal blood to test for trisomies. However, the lab which did the test did not have coverage with our insurance and I would have had to have it done at another facility and be responsible for it out of pocket. That tests for three trisomies, 21, 13 and 18 starting at 10 weeks.
Well, the midwives had encouraged me to do some of the 'afp' screening...however, due to my age, being on the fluffy side and not being exactly sure of dates I knew even doing the quad screen would make it highly likely to get a false positive then be left uncertain of what to do next, if anything. So, at that point I had figured that I wouldn't do any testing. But, I'll admit I was stressing and kind of worrying about things being 'normal' since this pregnancy was unexpected and I'm an older mom now.
Well, I found out from another forum a couple of days ago, that a similar test is now available through a labcorp company which also tests for fetal dna in the mother's blood. It's call the Harmony Prenatal Test. The cool thing about this is that this company is contracted with most insurance companies! I did more research in the last two days, found out that my insurance company covers it and the facility is in network. The funny thing is, the test is so new that it seems like only a limited amount of people seem to know about it. This similar test through the lab corp company actually has only been available about a month! But it looks like their clinical research detected 99% of the trisomies and there was only a false positive rate of 0.1% which is far more accurate than the NT and other combined screens.
So, I think I'm going to go for this one, I had quad screening done with past pregnancies though this time being older this seems like a better, more accurate option.
