What is the difference between cortisol and free cortisol?
What is the difference between cortisol and free cortisol?
Free cortisol is the physiologically active form of the hormone. In a healthy person, 10% of the cortisol is present in the free form, 20% is bound to albumin, and 70% is bound to cortisol binding globulin.
What is a critical cortisol level?
Most critically ill patients have a normal random free cortisol level of >1.8 μg/dL, although further studies are needed to define a normal range in critically ill patients based on both severity and duration of illness.
What is cortisol rhythm?
Cortisol has a particular circadian rhythm that is affected by sleep. Based on normal physiology, lower levels of cortisol are present at the initial part of sleep, whereas there is an increase at the end of the sleep period, which reaches its peak just minutes before the individual wakes up.

What happens when your cortisol level is too low?
If the level is too low, your brain adjusts the amount of hormones it makes. Your adrenal glands pick up on these signals. Then, they fine-tune the amount of cortisol they release. Cortisol receptors — which are in most cells in your body — receive and use the hormone in different ways.
What is the normal range of cortisol levels?
Free cortisol level testing is not available at most hospitals. A majority of experts will agree that a random serum cortisol <10 mcg/dL is low and >34 mcg/dL is high. Controversy of how to interpret levels between 10 and 34 mcg/dL exists (4, 5).
How do the adrenal glands affect cortisol levels?
Your hypothalamusand pituitary gland — both located in your brain– can sense if your bloodcontains the right level of cortisol. If the level is too low, your brainadjusts the amount of hormones it makes. Your adrenal glands pick up on these signals. Then, they fine-tune the amount of cortisol they release.
