AI blood test finds silent liver disease years before symptoms

Researchers created an AI-driven liquid biopsy that scans patterns in fragments of DNA circulating in the blood. The system detected early liver fibrosis and cirrhosis—conditions that often go unnoticed until serious damage occurs. By analyzing genome-wide DNA fragmentation patterns rather than specific mutations, the approach captures hidden signals about a person’s overall health. Early detection could help doctors treat liver disease sooner and potentially prevent cancer.
