The biomarker p-tau 217 best correlated with other established signs of Alzheimer's disease in a head-to-head study evaluating six blood-based assays.

In a recent study, the 48-protein panel improved the diagnostic performance of existing Alzheimer's markers and helped predict progression of the disease.

The researchers developed a plasma protein signature that can identify patients with cerebrospinal fluid amyloid-β42 levels indicative of risk for the disease.
