A new finger-prick blood test detects Alzheimer’s with 86% accuracy using dried blood spots, enabling earlier, non-invasive screening.
A new finger-prick blood test detects Alzheimer’s disease with 86% accuracy by measuring key biomarkers in dried blood spots, according to a study in Nature Medicine.
The method, validated across four countries, could enable earlier diagnosis without invasive procedures, supporting early treatment and large-scale screening, especially in remote areas.
While promising for research and high-risk groups, experts caution against clinical use until further validation, noting risks of misuse in direct-to-consumer settings.
