NCT ID NCT07187921

First seen Jun 27, 2026 ยท Last updated Jun 27, 2026

Summary

This study looked at whether a finger prick blood sample can accurately measure a key Alzheimer's biomarker (pTau-217) compared to a standard blood draw. 49 adults already in another Alzheimer's study provided both types of samples. The goal was to see if the finger prick method is accurate, easy, and acceptable for future at-home testing.
