My PhenoAge: 20.17 years

Result at a glance

The basis is my blood panel from 19 September 2025. My chronological age on that day was 34.57 years. The nine mandatory markers of the clinical PhenoAge produce a value of 20.17 years.

That works out to roughly 14 years and 5 months below my chronological age. This is a model-based estimate – not a diagnosis and not a statement about individual life expectancy.

How the value is produced

The nine markers and chronological age are weighted with the coefficients from Levine et al. (2018). This yields a linear predictor that a Gompertz function translates into a ten-year mortality risk. That risk is then converted back into an age in years – the PhenoAge.

This is the clinical PhenoAge from blood values, not the DNA-methylation-based DNAm PhenoAge. Both carry the same name but measure different things and are not directly comparable.

How this differs from my Bortz Age

In parallel I calculated my Bortz Age from the same blood panel. Both models pointing in a similar direction does not make them identical: they use different markers, coefficients and reference cohorts, so the results must not be equated.

Context and scientific limits

The Levine model was developed on a NHANES cohort whose participants were on average considerably older than I was at the time of measurement (34.57 years). The calculation is therefore an extrapolation to the edge of the age range studied.

Lab values fluctuate by day, method and laboratory. A single measurement is a snapshot, not a diagnosis. What matters most is the trend across several measurements taken at the same lab.
