Part Description
LP14161-1 Cortisol
Cortisol is a glucocorticoid produced in the adrenal cortex. A synthetic version of this same chemical is called hydrocortisone and manufactured as medication. Cortisol is not to be confused with cortisone, a closely related compound with much less (PubChem calls it "inactive") biologic activity. Cortisone is also offered as a drug, and it is converted to cortisol (the active form) in the liver. They both have a circadian rhythm with peak in the AM (around 8AM) and trough in the evening (around midnight), but this shifts according to sleep habits (work shifts). The morning measurement, which should be high, is most useful for diagnosing Addison's disease (too little cortisol) and the evening measurement, which should be low, is the most useful for diagnosing Cushing's disease (too much cortisol). Salivary cortisol may be a more sensitive measure than serum or plasma.
