What is PhenoAge?

PhenoAge (phenotypic age) is a biological age estimate computed from a set of clinical biomarkers and chronological age. It is designed to summarize mortality and morbidity risk signals into an age-like metric. This page provides educational information and should not be used as medical advice.
