This thread made me wonder if anyone did or will do the MaterniT21 PLUS test, which screens for trisomies 21, 18 and 13 (21 causes Down syndrome). Because I'm 35 now and I heard how this test is super accurate (compared to the screens that just give you probabilities--stress!) and no risk to the baby, I decided to do it. My CPM midwife had heard of it but had never used the test before. She called the company, which got test kits to her, and then came last week to draw my blood. It can be done after 10 weeks of pregnancy. I did it at 11 weeks just for logistical reasons and to be 100% sure I was past 10 weeks. I got my results (negative!) today, and I am so happy I did the test. If it weren't available, I probably wouldn't have done any testing but I'd feel a little worried.
Wondering if anyone else had experience with it. I hope this test becomes more widely known so that as many women women don't have to deal with those pesky probabilities offered by the screens, or with the risks of more invasive testing. I sound like an ad, but it really is so liberating to me!
