LH, FSH and Estradiol Interpretation
Endocrine Laboratory Assessment and Functional Testing
LH, FSH and Estradiol Interpretation
LH, FSH and estradiol together help characterize reproductive feedback and ovarian or central function.
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
Interpretation changes with cycle phase, menopause, medicines and clinical context; a normal-range gonadotropin can still be inappropriate for a low sex-steroid concentration.
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.
