Published reference ranges
Published values for Testosterone, total vary along 4 axes:
- sex
- age
- time of day (AM preferred)
- Tanner stage in adolescents
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.
