Biological Age Test Explorer: Functional vs. Molecular Testing
Which biological-age testing approach fits what you want to learn?
Compare functional-performance testing with laboratory-based approaches in about 60 seconds. No email, medical history, or personal score is required.
AgeMeter measures functional performance. It does not measure DNA methylation and does not replace medical care. Different biological-age approaches measure different aspects of aging and can be complementary.

What do different biological-age tests measure?
| Approach | What it observes | Typical experience |
|---|---|---|
| Functional-performance testing | Current performance in defined sensory, cognitive, movement, strength, balance, or related tasks, depending on the test. | Guided tasks with results available after the assessment; repeat testing may be used to follow performance over time. |
| Molecular testing | Biological signals such as DNA methylation or other molecular markers. | Usually requires a collected sample and laboratory analysis. |
| Clinical or blood-based composites | Selected laboratory or physiological measurements combined by a model. | Requires the specified measurements and depends on the model and reference population used. |
| Questionnaire calculators | Self-reported habits, history, or other answers. | Fast and accessible, but not a direct performance, molecular, or laboratory measurement. |
No method produces a universal “true age.” Ask what was measured, what the model was designed to estimate, which reference population was used, and what a change in the result has actually been shown to mean.

Evidence boundary: AgeMeter results are for informational assessment and tracking. They are not a medical diagnosis and should not direct treatment. A change in any biological-age or functional score is not, by itself, proof that aging has been reversed, disease has been prevented, or lifespan has been extended.
