DEXA Lean Mass Analysis

Meaning

DEXA Lean Mass Analysis is a precise clinical measurement derived from Dual-Energy X-ray Absorptiometry (DEXA) scanning, which quantifies the total mass of non-fat and non-bone tissue in the body, primarily representing skeletal muscle. This assessment provides a regional and total-body breakdown of lean tissue, offering a highly accurate, objective metric for monitoring sarcopenia, evaluating the efficacy of hormonal or exercise interventions, and assessing overall metabolic health. It is the gold standard for tracking changes in muscle mass over time.
