Alzheimer’s Assay Gets Breakthrough Designation
FDA has granted Beckman Coulter Diagnostics a breakthrough device designation for its Access p‑Tau217/β-Amyloid 1-42 plasma ratio assay, a blood test to help identify patients with amyloid pathology associated with Alzheimer’s disease. The company says the assay measures the ratio of phosphorylated tau protein (p-Tau217) to β‑Amyloid 1-42, two key biomarkers implicated in the neurodegenerative processes of Alzheimer’s disease. “A blood-based IVD test that can quantify these biomarkers in plasma could provide a non-invasive, accessible, and earlier method of detecting Alzheimer's-related pathology,” it says.
