New Blood Test Predicts Risk of Disease by Estimating Organ Aging

Study finds nearly 20% of healthy adults have at least one organ aging faster than others, increasing risk of disease or death.

Scientists have developed a new method to estimate the biological age of organs in a person's body, which can predict the risk of disease related to that organ.
The study found that nearly 20% of healthy adults have at least one organ aging faster than others, increasing the risk of disease or death.
The research involved examining blood samples from over 5,600 adults and using machine learning to identify proteins associated with aging produced by specific organs.
Individuals with accelerated aging in the heart were found to be 2.5 times more likely to experience heart failure, while those with aged brains were 1.8 times more likely to show cognitive decline over five years.
The findings may pave the way for a simple blood test to detect early signs of disease and prevent it before it strikes.
