Tests that measure 'biological age' aren't helpful for tracking your health, scientists say
Scientists argue that tests measuring biological age are not effective for tracking individual health. While these tests can be useful for studying populations, they often yield unreliable results for individuals. The tools, based on epigenetic aging clocks, do not meet the standards of common medical tests.
- ▪Biological age tests are marketed by numerous companies, with prices ranging from $30 to over $1,000.
- ▪Epigenetic clocks are effective for population-level studies but not for individual health assessments.
- ▪The chemical changes in DNA measured by these clocks can reflect aging influenced by lifestyle and environment.
