I’m reposting in an easier format to read (thanks Greygoose)

Just an update, I’ve had the retest results through on Saliva Cortisol tests and full Thyroid check If its ok I’ll post them here, any and all advice welcome. Ive just made an appointment with GP for 23/5/18 (earliest) re Cortisol results to ask for blood test.

Waking. 3.810. (6 - 21)

Midday 1.870 (1.50 - 7.60)

4pm. 1.560. (0.00 - 5.49)

Bed time. <1.5. (0.00 -1.9)

So it’s dropped a bit since last test 2 weeks ago.

Thyroid has come back ok results are:

Hi, your adrenal glands do seem to be struggling a bit, especially the morning levels which as you know should be at their highest level dropping off during the day and lowest at night. I presume you didn't have DHEA tested at the same time? DHEA is an androgenic hormone and is the precursor for testosterone and the estrogens. DHEA antagonizes the effects of cortisol and they should be viewed together as a ratio and like every major control system in the body should work in balance.

If you want to read more about the adrenals/DHEA there are a couple of good sites (in my opinion) you might find of interest:-



I presume your GP will do the serum morning cortisol test, the problem with that test is that it shows bound and unbound cortisol and is most likely to give you a higher morning reading. GP's generally only look for the extremes of adrenal fatigue i.e. Cushing's or Addison's, anything in between is considered normal!!


Take care, best wishes


Thank you Cassie0707 I’ll have a look at both of those sites.
