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. 

Why get a cortisol test?

Are you worried that you might be facing too much stress in your daily life? You can now definitively find out how much stress you encounter with our advanced home cortisol test. We can accurately measure the levels of your adrenal hormone to gauge how much of the stress hormone your body is producing.

Symptoms of elevated cortisol levels include:

  • Increased fatigue
  • Muscle weakness
  • Skin changes: bruising, red flushes, rashes
  • Anxiety
  • Mood swings
  • Increased heart rate
  • Feeling of thirst or the need to frequently urinate


Additional Information

There are a few different types of cortisol blood tests that can be administered, depending on your needs and what you are wanting to test for. The most common type of cortisol blood test is the serum cortisol test, which measures the amount of cortisol in your blood serum. This type of test is used to check for Adrenal Hyperfunction, which is a condition where the adrenal glands produce too much cortisol. This can be caused by a variety of things, including stress, Cushing's disease, or Addison's disease.


Another type of cortisol blood test is the plasma cortisol test, which measures the amount of cortisol in your blood plasma. This type of test is used to check for adrenal insufficiency, which is a condition where the adrenal glands do not produce enough cortisol. This can be caused by a number of things, including adrenal gland tumours, pituitary gland problems, or certain medications. Lastly, there is the urinary free cortisol test, which measures the amount of free cortisol in your urine. This type of test is used to check for Cushing's syndrome, which is a condition where the body produces too much cortisol. If you are experiencing any of the symptoms of one of these conditions, it is important to get tested so that you can get the appropriate treatment.

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.
