Bioavailable Hormone Metrics

Meaning

Bioavailable Hormone Metrics are a set of clinical measurements used to quantify the portion of a hormone that is unbound or loosely bound to carrier proteins, thus representing the fraction immediately available to exert biological effects on target tissues. These metrics include free hormone concentrations and the calculated bioavailable fraction, which typically includes the free hormone plus the albumin-bound fraction. They offer a superior clinical assessment of functional hormone status compared to total hormone levels, which can be misleading due to variations in carrier protein concentrations.
