Plasma p‐tau181 concentration accurately predicts clinically diagnosed Alzheimer’s Disease cases

The feasibility of detecting tau phosphorylated at threonine‐181(p‐tau181) in CSF makes it a valuable biomarker for diagnosis in the field of Alzheimer’s Disease (AD). Recently, the novel technologies accurately measuring biomarkers directly in blood offer a unique advantage for use in clinical testing and trials. This study describes the performance testing of a novel plasma p‐tau181 Simoa assay to predict clinical AD.
