Finger-prick blood test could speed up early Alzheimer’s detection, trial suggests

An international Bio-Hermes-002 trial spanning the UK, US, and Canada is testing a finger-prick blood test that looks for three Alzheimer’s biomarkers to diagnose the disease noninvasively. About 883–1,000 participants aged 60+ are being enrolled to compare the test against standard invasive diagnostics, with researchers and NHS experts stressing that earlier, accurate diagnosis is crucial as new treatments become available.
