a, Collection and processing of venous plasma and capillary DPS and DBS samples. For DPS and DBS sample collection, a finger prick was carried out by trained study personnel and a few drops of capillary blood were spotted onto DPS and DBS collection devices. DPS and DBS were collected via semi-automated spot collectors and incubated with analyte-specific extraction buffer in a 96-well filter plate. After incubation and centrifugation, the eluate was immediately measured using ultrasensitive immunoassays on the single molecule array platform. b–f, Participant numbers and collection device numbers per cohort: capillary p-tau217 (b), capillary GFAP (c), capillary NfL (d), DS cohort (e) and self-sampling cohort (f). Panel a created using BioRender.com.
