Header: See a detailed review of rapidly emerging Alzheimer blood tess, especially pTau217.
I did an MD-PhD with the intention of working in Alzheimer's research, and neuro disease was my focus from 1988 to 2001. Even in the 90's, there were regularly promises of a new Alzheimer blood test, which never panned out.
So I was excited to see a feature article in 360Dx by Adam Bonislawski about the rapid publications and advances in Alzheimer blood tests. Both plasma ABeta 42/40 ratio and Tau epitopes are promising. The article focuses on large new clinical reports that highligh phopho-Tau 217.
- "Plasma phosphorylated-tau 217 (p-tau 217) has emerged as a highly promising marker of the brain amyloid pathology characteristic of Alzheimer's and one that could lessen demand for plasma amyloid-beta 42/40 (Aβ42/Aβ40), the first blood-based marker for the disease to come to market."
