Adrenal Reactivity Assessment

Meaning

A clinical diagnostic procedure used to evaluate the dynamic functional response of the adrenal glands, specifically their capacity to produce and regulate stress hormones like cortisol and DHEA in response to a physiological challenge or throughout a diurnal cycle. This assessment moves beyond single point-in-time measurements to reveal the overall pattern and reserve of the hypothalamic-pituitary-adrenal (HPA) axis. Understanding this reactivity is crucial for identifying patterns of hormonal dysregulation, which may manifest as chronic fatigue or poor stress adaptation. This testing provides actionable data for personalized intervention strategies in hormonal health.
