Plasma amyloid-β oligomerization assay as a pre-screening test for amyloid status

Additionally, we examined long-term storage effects on plasma OAβ.We included 399 subjects regardless of clinical diagnosis from the Amsterdam Dementia Cohort and European Medical Information Framework for AD project (age, 63.8 ± 6.6; 44% female).
