I know that the 20 week scan picks up major structural abnormalities, and it also picks up "soft" markers aswell. I was wondering if anyone knows how accurate they are? Would it always pick up downs (ie. does downs usually have a lot of soft markers which would likely be seen)? I want to put my faith in the scan but am worried about how much they might/can miss. Any advice would be really helpful.
Thanks!
