Longevity Testing Evolves Beyond Lifespan to Focus on Healthspan Metrics
Longevity testing has significantly evolved, moving beyond simply predicting lifespan to focusing on 'healthspan'—the duration of life spent in good health and function. This shift involves assessing how well vital physiological systems, such as the cardiovascular system, metabolism, muscles, and brain, perform as individuals age. While traditional blood tests remain foundational for monitoring healthy aging by tracking markers like blood pressure, glucose, and cholesterol, newer technologies are gaining prominence. These include epigenetic clocks that measure biological age through DNA methylation patterns, advanced cardiovascular biomarkers like Apolipoprotein B (ApoB) and Lipoprotein(a) [Lp(a)], continuous glucose monitoring (CGM) for personalized metabolic insights, and the assessment of muscle strength, particularly hand grip strength, as a powerful longevity marker. Wearable technology also contributes by providing longitudinal data on heart rate, activity, and sleep.
