Bio-Available Hormone Metrics

Meaning

Bio-Available Hormone Metrics represent the quantitative clinical measurement of the fraction of a hormone in the circulation that is unbound to carrier proteins and is therefore free to engage with its target cell receptors. This specific, physiologically active concentration, often encompassing free testosterone or free cortisol, provides a more accurate and functional reflection of hormonal activity at the tissue level than total hormone concentrations. Clinical assessment of these metrics is critical for determining the true functional status of the endocrine system and for guiding precise, personalized hormone optimization strategies.
