Validation of an Ultra-Sensitive Method for Quantitation of Phospho-Tau 217 (pTau217) in Human Plasma, Serum, and CSF using the ALZpath pTau217 Assay on the Quanterix HD-X Platform

Both blood (plasma and serum) and CSF tau phosphorylated at Threonine 217 (pTau217) have been shown to be able to discriminate early to mild Alzheimer's disease (AD) from non-AD neurodegenerative disorders and healthy controls with high sensitivity and specificity.
