Terms of Use
Understand how this directory is prepared and used.
Educational use
Biological Age Index provides general educational information. It does not establish a clinician–patient relationship, diagnose conditions or provide a personalised treatment plan. Consult a qualified clinician about symptoms, clinical laboratory results or medical decisions.
Estimates and changing information
Biological-age outputs are model-dependent estimates. Different methods may disagree. Source dates, provisional evidence assessments and unknown fields should be read alongside the main content. Prices, features, eligibility and provider policies may change.
Purchases and external content
Any purchase is made directly with the test provider under its own terms. We do not process biological samples or guarantee test availability. Links to research and provider material do not imply affiliation.
Preview status
The initial content is a draft awaiting independent editorial and public-launch legal review. These terms describe intended use without removing rights that apply under mandatory law.
