What is the lab range? Every lab differs. The time done is good.
Also, was this the only test done, and the only time cortisol was done? Cortisol can vary - and testing only once... it should be done several times - and if consistently low, a stim test should be done.
Sodium and potassium needs to be looked at as well.
Lab ranges say <5 . I have to take another one plus 24 hour urine also.. I just feel so like I got hit by a bus I am so tired and body aches like back and legs and a headache that will not go away. I also have really low blood pressure and get dizzy all the time .
Low blood pressure is another symptom consistent with AI. That goes along with the sodium and potassium readings - did they do any? The 24 hour test will help as well.
The aches can come from the cortisol changes. Cortisol is a natural anti-inflammatory so when it is low, things hurt a lot.
Are they doing any other testing like renin, aldosterone, dhea sulfate, antibodies and ACTH?
Weird that they have not done a CMP - comprehensive metabolic panel at least for electrolytes to get sodium and potassium. That would tell a lot. Headache is so difficult - hard to determine a source when it could be so many things!
Odd they are focusing on sugar though. To me anyway.
They run the creatinine to make sure that you are not over-sampling (as in save more than 24 hours worth of pee... because it is so so much fun)...
I am not sure why that is low. "Low blood levels of creatinine are not common, but they are also not usually a cause for concern. They can be seen with conditions that result in decreased muscle mass."
The cortisol is on the lowish side - did you keep it cold the entire time?
Your ACTH is fine. All the other tests fine as well...
Yes I kept it in frige the whole time, I am still feeling so weak and still very low blood pressure. My doc said test results were fine, and threw me some anti depressants So typical.. I dont know what to do anymore I am very tired of feeling so blahhhhh. Is there any other test I should ask for?
That set was fine - but alas, cortisol testing takes time - and should be done in several sets over time as it can vary quite a bit. Plus the symptoms can overlap with other things - so you would need a good endocrine check. But the normal sodium and potassium pretty much means low cortisol may not be the issue as Addison's is a salt wasting disease and those would be off if you had low cortisol - they would be at the low end (or K at the high end).
Fatigue is a difficult symptom as it can be endocrine, auto-immune (see a rheumy?) vitamin deficiencies, low iron, etc etc etc...
