Japan develops AI blood test for measuring biological age

Scientists in Japan have created an AI blood test that measures biological age using just five drops of blood. This test analyzes 22 steroids, including cortisol, to assess organ health and the impact of stress. Unlike traditional DNA tests, this new method offers a more direct evaluation of how well the body is aging. It focuses on the health of vital organs rather than chronological age. The AI model identifies interactions between steroid molecules and cells. Researchers found that increased cortisol levels can significantly raise biological age, highlighting the effects of stress on health.
