Healthy Cortisol levels

[A_omshanti]

Hi am new here and wanted to introduce myself .

I would like to know wa hat are the cortisol levels range Morning and afternoon.....

[SeasideSusie Remembering]

According to rt3-adrenals.org/cortisol_t...

Optimal levels for a cortisol *saliva* test are

• Morning at the top of the range

• Noon approximately 75% of the range

• Evening close to 50% of the range

• Nighttime at the bottom of the range

Nobody can tell you what the ranges (reference intervals) are as they differ from lab to lab.

If you have had a test done, the range should be with the result.

Thank you

This link will take you to a chart which shows what normal cortisol levels are in a healthy person based on information gathered from several hundred people by a leading Endocrinologist. (Look on page 2) cahisus.co.uk/pdf/CIRCADIAN... Cortisol varies through the day with it being the highest first thing in the morning. Endo's will do various tests depending on whether the result is high or low.

Hi

I’ve had differing low levels of cortisol. As low as 68 in the afternoon with a range of 155-600.

Although I felt extremely unwell and have had 7 low cortisol results with a few months last year have had no medication. I had a synacthen test and it was normal. My thyroid has been all over the place which I’m still trying to get my levels optimum. My sister has just had a 9am result of 100 range is 155-600

She had a synacthen test last week and it was normal! 100 result at 9 am is normally automatic Addison’s. It’s not Addison’s they said. However, my sister had thyroid cancer and has to keep her TSH completely suppressed at zero therefore she has to take high dose of Levothyroxine which sends her T4 over the range. Could it be Levothyroxine so high is causing cortisol to be so low!??

Did they do a ACTH blood test at the start of the synacthen test? The blood for this needs to go on ice straightaway. Sadly many Enod's aren't very good at interpreting results & will say that an SST is normal if the values double, that only means that the adrenal glands are responding, the ACTH will show what is happening in the pituitary gland. Addisons (primary) is where the adrenal glands don't work, however secondary adrenal insufficiency is where the issue is with the pituitary. You both need an Endo who is conversant in pituitary/adrenal issues. TSH is affected when there is a pituitary issue, T3 & T4 needs to be done instead.

Hi. My Endocrinologist is a world leader and insists I have no adrenaline issues. He said, which I thought was as you say, that if the SST is normal I don’t have primary or secondary.

Thanks for your reply it is really appreciated
