Bioavailable Hormone Indexing

Meaning

Bioavailable Hormone Indexing is the clinical assessment and subsequent interpretation of the fraction of a hormone that is unbound to carrier proteins, such as sex hormone-binding globulin (SHBG) or albumin. This index provides a more accurate representation of the hormone’s biological activity at the tissue level compared to measuring total hormone concentration alone. Clinicians use this metric to gauge the true physiological impact of key hormones like testosterone and estrogen. Accurate indexing is paramount for effective and personalized hormonal health management.
