Aging
Telomere Length
Measures the length of protective caps on chromosome ends — a marker of cellular aging and replicative capacity.
Optimal Range
Age-adjusted percentile (>50th = favorable)
Why It Matters
Telomeres shorten with each cell division and with chronic stress, inflammation, and poor metabolic health. Shorter telomeres are associated with increased disease risk and mortality, though the clinical utility of single measurements is debated.
