Preventive medicine does a huge leap with a study published in Nature Medicine, where researchers at Stanford University announce a blood test capable of estimating the biological age of each body. With the help of artificial intelligence, the analysis could become a routine tool for early disease detection, completely changing how doctors approach health.
The method is based on the measurement of thousands of blood proteins and their comparison with the average values associated with a certain age. Thus, the test indicates whether an organ is “younger” or “older” than the chronological age of the patient shows. The technology was validated on a sample of over 45,000 people in UK BioBank, and the results were impressive.
Hidden risks
The conclusions are worrying: a higher biological brain brings a 12 times higher risk of Alzheimer in the next 10 years. The same correlations were observed for kidneys, liver and pancreas. Among the factors that accelerate the aging of the organs are smoking, excessive alcohol consumption, lack of sleep and rich diets. In contrast, exercise, consumption of fatty fish or supplements such as glucosamine and estrogen seem to reduce the biological age of the organs.
The discovery is not only at the laboratory stage. A concrete example is that of entrepreneur Paul Coletta, in which the test identified “aging” kidneys at the age of 68, although the classic analyzes seemed normal. An ultrasound later confirmed the existence of a renal cyst. Impressed by the accuracy of the test, Coletta has founded Vero Bioscience, who wants to sell it for about $ 200 and develop a digital health monitoring platform at home.
