Study Finds Performance Variation Among Commercial Alzheimer’s Blood Tests

The CLEAR-AD study highlights the need for platform-specific calibration for plasma p-tau217 assays to ensure diagnostic accuracy. The Clinical Evaluation of Blood-Based Tests for the Rapid Identification of Amyloid Pathology in AD (CLEAR-AD) study found significant performance variations among nine commercially available plasma p-tau217 assays. The findings, published in Science Bulletin, indicate that these blood tests for Alzheimer’s disease …

New Blood Test Could Reveal How Far Alzheimer’s Has Progressed

Alzheimer’s disease begins changing the brain many years before memory problems become obvious. Scientists can now detect some of these hidden changes with blood tests, making diagnosis easier than it was in the past. A new study suggests that measuring a small group of blood proteins together could also help doctors estimate how far the […] The post New Blood Test Could Reveal How Far Alzheimer’s Has Progressed appeared first on Knowridge Scien…

Blood Test Predicts Alzheimer's Risk a Decade Early

A blood test detecting p-tau217, a protein linked to Alzheimer’s, may help predict cognitive impairment in older adults a decade before symptoms appear.
