"The Truth About Biological Age Tests: Accuracy, Interpretation, and Business Boom"

Biological age tests, based on DNA methylation, estimate how fast or slow a person is aging compared to peers. While they can provide insight into overall health and potential lifespan, experts caution that the results should be interpreted alongside clinical variables and other health assessments. The tests are currently more useful for scientists studying aging, and their practical application for consumers is limited. However, researchers hope to use DNA aging tests in clinical trials to determine whether lifestyle changes or interventions can slow down aging.
