I had my Maternal Serum Screening & Nuchal Translucency/Nasal Bone Sonogram to assess risks for Down Syndrome, trisomy 13, and trisomy 18, and my risk for Down Syndrome came back as 1 in 23.
I'm going to be 40 at delivery and I know that factors into it but the free beta-human chorionic gonadotropin (hCG) came back in the 95% and pregnancy associated plasma protein-A (PAPP-A) was in the 10th percentile, so although the nuchal transparency came back looking good and the technician found a nasal bone, that is what sent up the red flag.
My midwife encouraged me to get CVS, and I'm going in for the test tomorrow. I'm just pretty nervous right now. I know there is a 5% rate of false positives with the testing I had and tons of anecdotal evidence that its not terribly accurate. But the CVS is supposed to be diagnostic and be 99% accurate....
Any comforting stories? Any advice?
