TeloTest — Biological Age Assessment

A telomere length measurement providing an estimate of biological age versus chronological age. Telomeres — the protective caps on chromosomes — shorten with age and cellular division, serving as a biomarker of biological ageing.

Telomeres are repetitive DNA sequences at the ends of chromosomes that protect genetic material from degradation during cell division. With each cell division, telomeres shorten slightly, and when they reach a critical length, the cell can no longer divide and enters senescence or apoptosis. Telomere length is therefore considered one of the most direct biomarkers of biological ageing, reflecting the cumulative impact of genetics, lifestyle, stress, nutrition, and environmental factors on cellular health. The TeloTest measures average telomere length from a blood sample, comparing the result against age-matched reference populations to estimate whether an individual's biological age is younger, equal to, or older than their chronological age. This metric provides a tangible, quantifiable data point that can serve as both a baseline and a motivational benchmark for individuals investing in longevity-oriented lifestyle changes. At EUR 500, the TeloTest is positioned as a mid-tier diagnostic within Qualevita's portfolio, accessible to individuals who want a meaningful longevity biomarker without committing to a full health program. It pairs particularly well with the clinic's Premium Longevity Program for those who want to track biological age alongside comprehensive biomarker panels. Repeat testing at 6- to 12-month intervals can help assess whether lifestyle interventions, supplementation, or treatment protocols are having a measurable impact on the rate of biological ageing.
