Aim/Results

Aβ1-17 (Aβ17) appears to be the second-most abundant cerebrospinal fluid (CSF) Aβ fragment, after Aβ40. AD patients have higher Aβ17 directly accessible from plasma than healthy controls. Although the confidence intervals are wide, these findings suggest that assessment of Aβ17 may increase the diagnostic performance of blood-based Aβ tests which might be developed into minimally invasive first-step screening tests for people with increased risk for AD.

What is Required from the Health System

blood draw, mild discomfort, in clinic visitsphlebotomist, equipped lab (e.g., centrifuge), a way to measure the peptide (e.g., mass spectrometer, protein assay kit, ELISA, or western blot)
