What it analyses

Not just how old you are, but how old your cells seem

Many age clocks read DNA methylation, which changes slowly. The GENEOMETRY® Clock reads microRNAs, which reflect current activity in your cells. It estimates how far your biological age sits from your calendar age.

Your report

Biological age at a glance

The report shows your result in years, on a scale from minus 10 to plus 10. Each microRNA is scored 1 to 9, with diet and lifestyle scores from a short questionnaire.

  • GreenIn the favourable range. The report suggests how to keep it there.
  • YellowIn the middle band. Your doctor explains what it means for you.
  • RedStands out. Your doctor prioritises it in your plan.
  • A fictional example report from HealthBioCare, the laboratory that runs the analysis. Your own report follows the same layout.

It measures three microRNAs and combines them into an estimate of your biological age at the time of the test. Your doctor goes through the report with you.

No. It is an estimate for discussion with your doctor, not an exact age or a prediction of lifespan. The model behind it comes from one early study, so treat the number as a rough guide.
