This type of test is used to check for Cushing's syndrome, which is a condition where the body produces too much cortisol.

Cortisol Levels

Cortisol is produced by the adrenal gland and has a massive impact on multiple physical and mental functions within the body. Cortisol is a steroid and is often referred to as the "stress hormone" due to it often being released when a person is in a perceived state of "stress". However it is not limited to this role within the body and is also involved in multiple metabolic and immune responses. Please note that cortisol levels fluctuate throughout the day with them peaking when you wake up and being lowest at the end of the day. Therefore it is important to take your blood test first thing in the morning when you wake up to make sure you measure them at maximum capacity.

Additional Insight from Dr Sameer Nakedar, MBBS, MRCGP, PGCert

Cortisol helps the body with many functions, including stress management, inflammation, blood pressure, metabolism, and blood sugar control. 

Conditions, where too much cortisol is present in the blood can result in symptoms such as weight gain, round face, marks on the skin, thin arms and legs, bruising or muscle weakness. 

High levels are seen in Cushing's Syndrome, when a person takes certain medicines (like steroids) or in certain tumours. Low levels of cortisol show symptoms such as fatigue, weight loss, muscle weakness, appetite loss and abdominal pain. Low cortisol levels are seen in Addison's disease or adrenal insufficiency, after certain infections, autoimmune disorders or brain injuries.
