Blood Tests of Phospho-Tau, Aβ42, Track With Brain Amyloid
Using mass spectrometry to detect teensy amounts of phospho-tau species in plasma, researchers reported that p-tau-217 and p-tau-181 picked out people with Aβ pathology. Differences between groups appear to be huge. An MS-based test for plasma Aβ42 corresponded to brain amyloid, and is going in for regulatory approval.
