TL;DR
How biomarker-based age estimates differ from birthday age, and why they guide prevention.
What is the difference between biological and chronological age?
Chronological age counts years since birth. Biological age models (such as PhenoAge) estimate how fast your body appears to be aging based on selected biomarkers.
A higher biological age than chronological age can motivate prevention; it is not a diagnosis by itself.
How do clinicians use biological age estimates?
Biological age estimates track response to interventions over time when paired with consistent lab methods. They complement, not replace, standard screening.
Interpretation requires clinical context: acute illness, medications, and lab variability all affect scores.
