Elecsys® Total-Tau and Phospho-Tau (181P) CSF assays : Analytical performance of the novel, fully automated immunoassays for quantification of tau proteins in human cerebrospinal fluid
Background: Total tau (tTau) and phosphorylated 181P tau (pTau) are supportive diagnostic cerebrospinal fluid (CSF) biomarkers for Alzheimer's disease. Manual CSF tau assays are limited by lot-to-lot and between-laboratory variability and long incubation/turnaround times. Elecsys® Total-Tau CSF and Phospho-Tau (181P) CSF immunoassays were developed for fully automated cobas e analyzers, allowing b
