This Alzheimer's blood test, PrecivityAD2, is based on the p-tau217 biomarker.
In one recent study, people very high p-tau217 had a 38% chance of progressing to cognitive impairment within 5 years vs 12% for those with low levels. The current tests cost about $200-300, so they're not unreasonable as a screening test.
