Telomere Length Testing

Telomere length testing measures the protective caps at the ends of chromosomes as a marker of cellular ageing and biological age. Shorter telomeres are associated with accelerated cellular ageing and increased risk of age-related conditions in research literature. Results inform personalised longevity and lifestyle programmes at Angel Longevity Medical Center in Studio City, Los Angeles.

Telomere Length Testing at Angel Longevity Medical Center quantifies the length of telomeres — the repetitive nucleotide sequences (TTAGGG) that cap the ends of chromosomes and protect them from degradation during cell division. Each time a cell divides, the telomere shortens slightly because DNA polymerase cannot fully replicate the terminal end of the chromosome; beyond a critical minimum length, cells may enter a state of senescence (permanent growth arrest) or apoptosis (programmed cell death). Telomere length is therefore considered a biomarker of cellular replicative capacity and biological age — individuals with shorter telomeres for their chronological age are said to have an accelerated cellular ageing trajectory. Epidemiological research has associated shorter leukocyte telomere length with higher risk of cardiovascular disease, cancer, diabetes, and all-cause mortality, though the mechanistic relationship is still under active investigation. The test at Angel Longevity uses blood to measure mean telomere length in leukocytes (white blood cells), which are the most accessible cell population and are commonly used in telomere research. Results are compared against age-matched reference ranges to estimate the patient's telomere age relative to their chronological age. Dr. Anju Mathur MD uses telomere length findings as one component of a multi-marker biological age assessment, combined with other longevity-focused biomarkers to guide personalised interventions — including nutrition, lifestyle modification, targeted supplementation, and hormone optimisation — that may be associated with supporting telomere length maintenance.
