Résumé
Quantification of tau proteoforms in cerebrospinal fluid (CSF) could be useful to help diagnose Alzheimer's disease (AD), other neurodegenerative diseases, and brain damage. In this article, LC-MS/MS results for tau and phosphorylated tau (pTau) are compared with in vitro diagnostic (IVD)-qualified immunoassay kits to distinguish between AD patients and control patients (1).
