FYI

Having 4 limbs is good but has nothing to do with whether or not a baby has DS. And also while it is good to see a nasal bone, some babies with DS do have a nasal bone. A good nuchal measurement is not a bad thing but just not enough to conclude no down. Of course you are right about the maternit21 test, as someone who had it I realize just because I got a negative doesn't mean my baby won't have down. My point was that you need the blood with that measurement to better decide if you want to proceed with further testing. You just can't say I had a good measurement I'm in the clear. That's all I am saying.
