Discover Your Biological Age
Calculate your physiological age using three scientifically-validated algorithms. Your biological age may differ from your chronological age based on your biomarker values.
Three Algorithms
KDM, PhenoAge, and Homeostatic Dysregulation - each validated in peer-reviewed research.
Instant Results
Get your biological age calculated in seconds from your blood test results.
Track Progress
See how lifestyle changes affect your biological age over time.
About the Algorithms
KDM (Klemera-Doubal Method)
Uses 10 biomarkers to estimate biological age based on regression analysis of biomarker changes with age. Developed using NHANES III data.
PhenoAge
Based on mortality prediction using 9 biomarkers. Developed by Morgan Levine and colleagues, correlates with DNA methylation age.
Homeostatic Dysregulation (HD)
Measures deviation from a healthy young adult reference population using Mahalanobis distance. Higher values indicate greater physiological stress.
You'll need values from a standard blood panel including:
Albumin, Creatinine, CRP, ALP, HbA1c, Cholesterol, Blood Pressure, and more.
