Welcome to HCM
I find that you are asking very interesting questions from morning about Cortisol
and now adrenal androgens!!!
Are you a Clinical Researcher or allied health professional?
In this forum where we usually give clinical advice and guidelines for investigations and management,I wonder whether we can answer to your satisfaction.
However I will try!
The DHEAS concentration is usually stable through out the day and can be measured any time of the day .
The timing of the test does not affect the test.
So this means that it is not secreted in pulses.
This is unlike cortisol.
Cortisol is highest after waking and very low at bedtime.
ACTH is tested usually in the morning at about 8 am and has circadian rhythm like cortisol.
Its levels are opposite to that of ACTH.
But your questions of how many pulses in children ,I can not answer. Sorry!
All the best
