Cortisol
A cortisol test measures the level of cortisol in your blood, urine (pee), or saliva (spit). Cortisol is a hormone made by your adrenal glands, two small glands that sit above your kidneys. Hormones are chemical messengers in your bloodstream that control the actions of certain cells or organs. Cortisol affects almost every organ and tissue in your body.

These labs do not agree for 18 y+ · morning: the published adult ranges differ by up to 52%, so the same result can read as normal at one lab and be flagged at another — ARUP 4.6–20.6 · Mayo 7–25 ug/dL. Both are real published values, shown as each lab states them.
