respectively, are defining physical features of Alzheimer's disease in the brain. Buildup of tau tangles is thought to correlate closely with cognitive decline. In these newly reported results, blood/plasma levels of p-tau 217, one of the forms of tau found in tangles, also...
"If we had ablood testfor tau as well, we could combine them to get an even better idea of who is most at risk of developing Alzheimer's disease," Bateman said. "That would be a huge step forward in our ability to predict, and maybe even prevent, Alzheimer's disease." More informa...
a blood test to detect the tau protein, one of the hallmark signs of Alzheimer's, was as accurate as a spinal tap or a positron emission tomography (PET) scan, which are the current gold standards of diagnosis while a person is living. ...
Across all the participants, the blood test predicted a diagnosis of Alzheimer’s disease with 88% to 92% accuracy. Further analysis found that measuring the proportion of p-tau217 alone yielded results similar to using both measures. The blood test performed far better than clinical evaluations ...

"We also show that a simple statistical model that takes into account blood glycan and tau levels, the risk gene APOE4 and a memory test can be used to predict Alzheimer's disease to a reliability of 80 percent almost a decade before symptoms such as memory loss appear,"saysmedical ...
according to a study.Called PrecivityAD2, the blood test combines the ratio of plasma phosphorylated tau 217 (p-tau217) relative to non-p-tau217 (expressed as percentage of p-tau217) and the ratio of plasma amyloid-p42 and amyloid-β40 (Aβ42:Aβ40), analysed by mass spectrometry. ...

(HealthDay)—When someone suffers a concussion, it can be hard to tell how serious it is and how long recovery will take, but a new blood test might help answer those questions. Swedish researchers report they have found a way to test blood for a protein called total tau (T-tau), whi...
