Biological Age Calculator

Biological age is a research concept for describing biological characteristics in relation to chronological age. Different methods measure different things and can give different results. This tool expresses a combination of health markers in years for educational exploration; it does not measure your body's true age.

For directional markers, the model compares your value with the NHANES sample mean and standard deviation for your age and sex, then converts that z-score into an age shift using a heuristic coefficient. Other markers use deviations from configured clinical ranges. The weighted average is adjusted for activity and sleep. It does not search for the age at which your value would be typical.

Clinical accuracy has not been established for this tool. Its weights and years-per-standard-deviation coefficients are heuristic, and the result has not been externally validated against mortality or clinical outcomes. The data-coverage badge counts optional markers; it is not a confidence interval or a measure of accuracy.

No. The calculator works with basic measurements alone. Coverage is basic without optional markers, additional with one or two, and broader with three or more. Blood pressure, waist circumference and blood-test values count toward coverage, not proven precision.

Changing inputs can change this model's result, but a lower estimate does not demonstrate rejuvenation or reduced health risk. The hypothetical scenario removes positive marker contributions and applies the best lifestyle adjustment in the model. It does not establish a treatment target; discuss abnormal measurements and appropriate changes with a healthcare professional.

Measured-marker reference statistics are derived from NHANES 2017–2018 (US CDC). The current processing uses age/sex sample statistics without survey weights and trims extreme values, so they are not representative US population estimates. The methodology lists clinical references separately from the model's heuristic coefficients.

No. MyAgeScore is an educational tool. It does not diagnose, treat or prevent any condition. If a marker looks abnormal, discuss it with a qualified healthcare professional.
