A head‐to‐head comparison of plasma phosphorylated tau assays in the real‐world memory clinic

Several blood phosphorylated tau (P‐tau) species (P‐tau181, P‐tau217, and P‐tau231) have shown high accuracy to detect AD pathology, but a direct comparison of the main blood P‐tau assays in a real‐world memory clinic is needed. The main aim of this study is to perform a head‐to‐head comparison of 9 plasma Tau assays and determine their accuracy to discriminate between symptomatic AD from non‐AD.
