Won't be a commercial diagnostic for use in the general populace but perhaps a predictive test to find those patients with mild cognitive impairment or pre-AD who will probably progress to moderate AD within 1-2 years.

Agreed that if(!) you have other statistically independent tests that in combo the overall predictivity may become acceptable. E.g. how many people classified as 'mild cognitive impairment' (a test of a kind) later go on to have alzheimers?
