TL;DR: In this paper, a seven-center inter-laboratory standardization study for cerebrospinal fluid (CSF) total tau (t-tau), phospho-Tau (p-tAU(181), and Aβ(1-42) was conducted as part of the Alzheimer's Disease Neuroimaging Initiative (ADNI).
Journal ArticleDOI

TL;DR: This study demonstrates that multiplex xMAP is an appropriate assay platform providing results that can be correlated with research-based ELISA values, facilitating the incorporation of this diagnostic biomarker into routine clinical practice.
Journal ArticleDOI
Validation of the Erlangen Score Algorithm for the Prediction of the Development of Dementia due to Alzheimer's Disease in Pre-Dementia Subjects.
Piotr Lewczuk,Johannes Kornhuber,Jon B. Toledo,John Q. Trojanowski,Malgorzata Knapik-Czajka,Oliver Peters,Jens Wiltfang,Leslie M. Shaw +7 more
TL;DR: The findings confirm the utility of the Erlangen Score algorithm as a useful tool in the early neurochemical diagnosis of Alzheimer's disease.
