About the Test

This cortisol hormone test can help determine the amount of cortisol present in your blood in the morning. Cortisol is the human body’s main stress hormone. It is necessary for the body to control things like fear, mood, and motivation. It also aids in regulating inflammation, blood pressure, blood sugar, sleep cycles and managing how foods are used, especially during stressful situations. Cortisol tests can help determine if there are issues with your body’s “alarm system.”

Cortisol is an essential hormone that plays a vital role in almost every organ and tissue system in the human body. The levels of cortisol change throughout the day to maintain a steady state. If you are experiencing any of the signs and symptoms listed below, this cortisol level test may be for you.

This cortisol blood test measures the morning level of cortisol present in your blood. The adrenal glands above the kidneys produce cortisol. Normally the body will regulate cortisol levels to deal with stress and pressure, but sometimes our bodies remain in a stressed state for too long. Too much (hypercortisolism) or too little (hypocortisolism) cortisol can result in the body’s inability to complete its normal functions and may lead to health problems such as anxiety, depression, headaches, memory issues, digestion problems, trouble sleeping, weight gain, and heart disease.

A cortisol imbalance test can help determine if the following signs and symptoms are due to:

Too little cortisol:

Overly tired
Worsening muscle weakness
Skin changes (darkening in folds & of scars)
Nausea/vomiting/diarrhea
Appetite loss/weight loss
Low blood pressure
Addison’s disease

Too much cortisol:

Trouble sleeping
Digestion problems
Headaches
Concentration/memory issues
Easy-to-bruise skin
Anxiety/depression
Weight gain
Heart disease
Cushing’s disease

FAQs

Is there a reason this blood test is to be completed in the morning?

Yes. Cortisol levels naturally change throughout the day. Cortisol levels typically peak in the morning, and the morning level would be the best single point indicator of a problem with your stress hormone.
