Morning serum cortisol levels are typically the first step in the diagnostic work-up, but this test is only significant if values are extremely low, adrenal insufficiency is almost certain with values below 3 μg/dl, or it can be excluded with values in the upper half of the normal range. Cortisol levels above 19 g/dl almost always rule out ...
Viral infections increase cortisol levels through activation of the HPA axis by cytokines. [100] Intense (high VO 2 max) or prolonged aerobic exercise transiently increases cortisol levels to increase gluconeogenesis and maintain blood glucose; [101] however, cortisol declines to normal levels after eating (i.e., restoring a neutral energy ...
Acid–base and blood gases are among the few blood constituents that exhibit substantial difference between arterial and venous values. [6] Still, pH, bicarbonate and base excess show a high level of inter-method reliability between arterial and venous tests, so arterial and venous values are roughly equivalent for these. [44]

To confirm inappropriately low cortisol secretion, testing can include baseline morning cortisol level in the blood or morning cortisol level in the saliva. [2] Cortisol levels typically peak in the morning; thus, low values indicate true adrenal insufficiency. [2] Urinary free cortisol can also be measured, but are not necessary for diagnosis. [2]
The long test uses 1 mg tetracosactide (intramuscular). Blood is taken 1, 4, 8, and 24 hours later. Normal plasma cortisol level should reach 1,000 nmol/L by 4 hours. In primary Addison's disease, the cortisol level is reduced at all stages, whereas in secondary corticoadrenal insufficiency, a delayed but normal response is seen.
Adrenal insufficiency can be diagnosed by testing renin, dehydroepiandrosterone sulfate, aldosterone, serum cortisol, and ACTH levels. [14] A high cortisol level of more than 13 to 15 mg/dL can rule out the diagnosis. A low cortisol level of less than 3 mg/dL, obtained in the early morning or during a stressful period, strongly suggests the ...
