Amyloid PET status was identified as the reference standard. For use as a triaging test before subsequent confirmatory tests such as amyloid PET or CSF tests, the BBM Workgroup recommends that a BBM test has a sensitivity of ≥90% with a specificity of ≥85% in primary care and ≥75–85...
Investigators found that changes in levels of these plasma biomarkers were positively correlated with percent change in amyloid plaque levels as shown on positron-emission tomography (PET). The results suggest these biomarkers could be used instead of the more expensive, and not always readily availabl...
In this study, we evaluated whether a precise blood test could perform as well as established cerebrospinal fluid (CSF) tests in detecting amyloid-β (Aβ) plaques and tau tangles. Plasma %p-tau217 (ratio of phosporylated-tau217 to non-phosphorylated tau) was analyzed by mass spectrometry ...
“But in time, if we can get a blood test, it will take us further, just as cholesterol tests did in the cardiovascular field,” says Hartley. Topics: Alzheimer’s More fromNew Scientist Explore the latest news, articles and features ...

useful for detecting and diagnosing Alzheimer's disease pathology," Bateman says. "Moreover, our assay for measuring plasma tau levels could be used as a highly sensitive screening tool to identify tau changes associated with amyloid plaque formation in normal subjects, replacing costly PET imaging....
That type of test measures a form of tau that correlates with how much plaque buildup someone has, Schindler explained. A high level signals a strong likelihood the person has Alzheimer’s while a low level indicates that’s probably not the cause of memory loss. ...

The team is targeting the two proteins themselves as a possible treatment for Alzheimer's disease. Mruthinti explains that, individually, amyloid-beta and RAGE proteins don't provoke an immune response. The trouble begins when the two bind and the immune system attacks, resulting in constant sta...
