Clinical utility
Isobaric with 11-deoxycortisol and corticosterone; chromatographic separation is required to resolve them. Immunoassay cannot.
Published reference ranges
Published values for 21-Deoxycortisol vary along one axis:
- time of day (AM / PM)
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.
