Understanding BioAge

Compare a blood-based estimate with your actual age.

BioAge combines your age with nine lab measurements and shows the estimate in years. It is educational information, not a diagnosis or prediction of lifespan.

How it is calculated

One estimate, with every input shown.

The calculation uses your age and nine results from your lab report. It follows the same formula each time; AI does not create the score.

  1. Our lab completes the reportAll nine required results must be available.
  2. The formula calculates the estimateThe same method and measurement units are used each time.
  3. You compare the numbersSee the estimate beside your actual age.

Measurements used

Nine lab measurements plus your actual age.

A score is only shown when every required result is available and valid.

When you retest

Compare the same calculation over time.

A future report can be compared with an earlier estimate when both use the same measurements and method.
