Normal values of cortisol and ACTH When assessed with a typical radioimmunoassay (the most commonly used method), cortisol levels range from about 10 to 20 micrograms per deciliter (ug/dl) in the early morning (within one hour of the usual time of awakening), from 3 to 10 ug/dl at 4 PM, and are usually less than 5 ug/dl after the usual bedtime, but there is a great deal of variation ...

Cortisol Not to be confused with cortisone, a metabolite from cortisol, with a similar name, genesis, and function. Cortisol is a steroid hormone, in the glucocorticoid class of hormones. When used as a medication, it is known as hydrocortisone. It is produced in humans by the zona fasciculata of the adrenal cortex within the adrenal gland. It is released in response to stress and low blood-glucose concentration.

Cortisol in Urine  [en EspaÃ±ol] Cortisol is made by the adrenal glands. Cortisol levels go up when the pituitary gland releases another hormone called adrenocorticotropic hormone (ACTH). Cortisol has many functions. It helps the body use sugar (glucose) and fat for energy (metabolism), and it helps the body manage stress.

- Vol. 11 No. 11 P. 38. Cortisol, a glucocorticoid (steroid hormone), is produced from cholesterol in the two adrenal glands located on top of each kidney. It is normally released in response to events and circumstances such as waking up in the morning, exercising, and acute stress. Cortisol’s far-reaching, systemic effects play many roles in the body’s effort to carry out its processes and maintain homeostasis.

Normal values of cortisol and ACTH There is an increase in cortisol secretion in response to eating and exercise as well as to physical and psychological stress. It is also important to recognize that these assays measure ‘total’ cortisol, most of which is bound to proteins in the bloodstream. Only the unbound cortisol is biologically active.
