Biological Age Testing Explained
How epigenetic clocks and other biological age tests work, what they can tell you, and where their limits are.
Glossary TermEpigenetic Clock
A biological age measurement tool that uses patterns of DNA methylation, chemical modifications to DNA that change predictably with age, to estimate a person's biological age.
ArticleWhat Is Biological Age?
Biological age estimates how your body is aging from measurable signals. It adds context to your birth year, but no single score can tell you how long you will live.
