Phenotypic Age Calculator
How old is your body really?

What Is Phenotypic Age?
Your chronological age is years since birth. Your phenotypic age is how old your body actually is based on how well your internal systems function. Two people born the same year can have very different biological ages—and the difference predicts disease risk and longevity.
This calculator uses the Levine et al. (2018) PhenoAge formula, validated in 11,432 adults. It measures 5 body systems using 9 routine blood biomarkers:
Science-Backed (UCLA, 11,432 adults) • Predicts Risk (mortality, disease, functioning) • Trackable (repeat every 3–6 months)
Don't Have Lab Results Yet?
You need 3 standard blood tests: CBC (Complete Blood Count), CMP (Comprehensive Metabolic Panel), and hs-CRP (C-Reactive Protein). * Direct lab ordering not available in NY, NJ, RI, or HI. Residents should request labs through their healthcare provider.Enter Your Lab Results
