Morning free cortisol in saliva; highest 7–9am; tests adrenal function.

The normal DHEA concentration alters significantly with age, gender and time of the day. During the day, DHEA values have the highest level in the morning and decrease over the day to the lowest level during night time. This pattern is somewhat similar to Cortisol. For this reason clear indication about the reference values is of utmost importance.
