Researchers Develop Blood Test to Measure Aging Across Body Systems

What's Happening?

Scientists have developed a new blood test that can measure the aging of 11 different physiological systems, providing a more detailed and personalized look at how the body changes over time. This test, known as Systems Age, uses DNA methylation patterns from a single blood sample to calculate a unique score for the biological age of systems such as the heart, lung, brain, metabolic, and immune system. The test was found to be more effective at predicting specific diseases and aging-related conditions than older epigenetic clocks, which provide a single-number biological age score. The research involved analyzing health data from over 7,500 individuals, linking blood-based biomarkers to age-related conditions in various organs.

Why It's Important?

The development of the Systems Age test represents a significant advancement in personalized medicine, allowing for more targeted treatments based on the specific aging patterns of different physiological systems. This could lead to improved healthcare strategies for managing age-related conditions, potentially reducing the risk of diseases such as heart disease and providing insights into individual health risks. By offering system-specific scores, the test may help doctors better pinpoint which age-related conditions individuals are at risk for, enabling more effective interventions and lifestyle recommendations.

What's Next?

The researchers suggest that the Systems Age test could be used to tailor medical treatments and lifestyle changes to better address the specific aging patterns of individuals. This could involve recommending strategies to boost immunity or cardiovascular health based on the test results. Further research and validation of the test could lead to its integration into routine healthcare practices, providing a valuable tool for assessing and managing aging-related health risks.
