Biological Age Tests: What Is an Epigenetic Clock Actually Measuring?

A biological-age report can look like a second birthday. But an epigenetic clock does not directly count how old every part of your body is. It applies a statistical model to measurements from a specimen. Before reacting to the number, find out what that model was built to predict. Trace a specimen through a methylation model and learn why repeatability, biological variation and a changed score require different evidence.
