Performance Reference Ranges

Meaning

Performance Reference Ranges are clinically derived, functionally oriented ranges for various physiological biomarkers, including hormones, metabolic markers, and nutrient levels, that are correlated with optimal health, high cognitive function, and peak physical performance. These ranges are typically narrower and often higher than the standard ‘pathological’ reference intervals used for disease diagnosis, which merely identify a statistically normal population. The clinical use of these ranges allows for the proactive identification of suboptimal function before it progresses to overt pathology, guiding targeted intervention for true health optimization.
