I had the 1st trimester screening done with my first pregnancy, at the time I was 42. My odds came back much much worse than yours, like 1:27 for downs, and my son is now 28 mos, healthy and beautiful. Your numbers all look great! Seeing the nasal bone is an excellent sign as well! Congrats...don't worry! Pam
I've read that those blood tests are notorious for giving nonfavorable results and the baby is fine..
If the u/s came out good, I would do my best to put that blood test out of my mind.
Congrats on your pg.
