Telomere Length Test

Measures the length of telomeres — protective caps on the ends of chromosomes that shorten with each cell division and serve as a biomarker of biological ageing. Shorter telomeres are associated with accelerated ageing, increased disease risk, and reduced cellular repair capacity. This test compares your biological age to your chronological age, providing a data point for tracking the impact of lifestyle interventions on ageing at the cellular level.

Telomeres are protective caps on the ends of chromosomes — repetitive DNA sequences that shorten with each cell division, functioning as a biological clock at the cellular level. When telomeres become critically short, cells enter senescence (they stop dividing and begin secreting inflammatory signals) or undergo apoptosis. Telomere length is considered one of the most direct biomarkers of biological ageing. This test measures your average telomere length and compares it to age-matched reference data, producing an estimate of your biological age relative to your chronological age. A biological age younger than your actual age suggests that your cells are ageing more slowly than average — a positive indicator for long-term health. The reverse suggests accelerated cellular ageing that may warrant lifestyle intervention. Factors known to accelerate telomere shortening include chronic psychological stress, sleep deprivation, smoking, excessive alcohol, sedentary lifestyle, obesity, and chronic inflammation. Factors associated with telomere preservation include regular exercise (particularly moderate aerobic activity), meditation and stress management, adequate sleep, a diet rich in antioxidants and omega-3 fatty acids, and strong social connections. This makes telomere length a useful feedback marker for people making lifestyle changes. Results take 5-7 business days due to the specialised chromosomal analysis required. ClearLabs delivers the results through a digital dashboard, showing your telomere length against age-matched percentiles. For those pursuing longevity protocols, serial measurements every 12-24 months can track whether interventions are having a measurable effect at the cellular level.
