Mothers in the UK get rough statistics based on their age (e.g. you're told you have a 1 in 8000 chance of having a kid with Down's), and have the option of an amnio, which is invasive and carries a risk of miscarriage, so many will go off the stats alone.
NIPT has only been around for a few years, whereas amnio has been available for decades AFAIK, so I guess it's amnio that's been commonly been available in Norway too?
