I feel as a train of thought strays into very unsettling ground. Any apparently, 'normal' child with no discernible disabilities may develop a debilitating illness or injury which hugely affects later life. A child with Down's, comparitively, might have a very good quality of life. With the information, we have concerning the future of our children, at this level, you might as well be dousing over them or reading their palms to decide their future prospects!
This is just saying that because we can't control everything, we should't try and control anything. The logical extension of that argument is saying that because some babies are stillborn or die soon after birth for reasons we can't predict, we shouldn't abort in cases of Edwards Syndrome which has a very high chance of stillbirth or death within a few days of birth.
Whatever way you look at it, a child diagnosed with DS has a much, much higher chance of severe health problems and poor life outcomes than a child born without DS. We can debate the exactly likelihood of these outcomes vs other more positive outcomes, but this is hardly palm reading.
If your perspective on life is to accept the cards you are dealt, whatever they are, then you wouldn't take the NIPT test in the first place, no-one is forcing it on anyone.
