Objective: The objective of this study was to examine clinicians' patient selection and result interpretation of a clinically validated mass spectrometry test measuring amyloid beta and ApoE blood biomarkers combined with patient age (PrecivityAD blood test) in symptomatic patients evaluat...
The results suggest these biomarkers could be used instead of the more expensive, and not always readily available, PET scans to monitor patients taking anti-amyloid agents. "We probably can't measure complete amyloid removal with a blood test, but we can see that something's happening and we...

Ideally, a blood test based on levels of Aβ1-42 in blood, as a reflection of a central nervous system pathological process, could be used to predict the risk of dementia much like levels of serum cholesterol are used to predict risk of coronary heart disease and candidates for drug therap...
Figure 1. Blood biomarker performance recommended by the Global CEO Initiative on Alzheimer’s disease.A triaging test aims to identify an individual unlikely to have amyloid pathology who may require further evaluation. A confirmatory blood biomarker test seeks to identify an individual with amyloid ...
"Although these findings have potential for supporting future research, exciting new developments in blood tests that focus on a different Alzheimer's protein, tau, hold the most promise for supporting an Alzheimer's diagnosis. "A reliableblood testwould be a huge boost for the dementia field. ...
(1795 - 1878) described a substance in woods that resembled starch. This substance reacted with iodine-sulphuric acid test similarly to starch, and Payen named it "cellulose". The iodine-sulphuric acid reaction became later on a standard procedure used by botanists to demonstrate the presence of...
