Clinical utility
Confirms dexamethasone exposure within a suppression test — a task immunoassay cannot perform.
Published reference ranges
Published values for Dexamethasone vary along one axis:
- dose and timing relative to suppression testing
Because a single unstratified figure would misrepresent them, none is shown here.
Published values vary by sex, age, time of collection, menstrual cycle phase and analytical method. The interval applicable to a patient's result appears on that patient's report.
