Blood test estimates biological ages of 11 separate organ systems to predict disease risk years ahead

Article excerpt

Researchers have developed a blood test that measures the biological age of 11 separate organ systems, brain, heart, lungs, liver, kidneys, and others, to predict disease risk years before symptoms appear. Unlike chronological age, biological age varies dramatically between individuals, reflecting differences in lifestyle, genetics, and environment. The test analyzes molecular markers in blood to determine how quickly each organ is aging, potentially allowing doctors to intervene early in patients showing accelerated aging in vulnerable systems. The approach moves beyond single-marker diagnostics, offering a more granular picture of how different organs degrade at different rates.
