Hormonal Biomarkers
Endocrine Laboratory Assessment and Functional Testing
Hormonal Biomarkers
Hormonal biomarkers are measurable indicators of secretion, hormone action or regulatory feedback.
Separate biological and analytical effects
Hormone results depend on secretion rhythms, binding, clearance, sample handling and the measurement method. Reference intervals and decision thresholds serve different purposes. Assay-specific interpretation is especially important near low concentrations and when results conflict with the clinical picture.
Specific considerations
A marker can be analytically reliable yet insufficiently specific for a particular diagnosis, so its clinical meaning depends on the question and population.
Define the testing question
Dynamic tests examine a regulated response under specified conditions. Their protocols, contraindications and thresholds require clinical oversight. A glossary explanation supports understanding and does not provide a self-testing or medication-adjustment protocol.
