Alzheimer’s device gets designation



A new blood test for Alzheimer’s disease has received a ‘breakthrough device designation’ from the US Food and Drug Administration for its promise as a way of identifying the disease early, and distinguishing it from other neurodegenerative disorders. The device, Elecsys pTau217 is an in vitro immunoassay intended for the quantitative determination of the protein phospho-tau (217P) in human plasma.
