Scientists develop blood test that reveals how fast your organs are aging

Stanford Medicine researchers developed a blood test that estimates the biological age of major organs by analyzing nearly 3,000 proteins. The test assigns ages to 11 organ systems, offering insights into aging disparities and predicting disease risk and longevity. The biological age of specific organs, particularly the brain, strongly correlates with disease risk and overall mortality. This breakthrough could revolutionize approaches to aging and disease, potentially enabling early interventions and new longevity strategies.
