How to check your Cortisol levels with a home finger-prick blood test kit

What Is A Cortisol Test For?

A Cortisol test is also known as a Serum Cortisol test.

Cortisol is your body's main stress hormone, influencing your mood, motivation, and fear.

The production and release of cortisol follows a circadian rhythm, highest in the early morning with several pulses throughout the day to the lowest levels in the evening.

This is called a diurnal rhythm and is clearly linked to daily activity patterns.

But cortisol is also released in high quantities in response to stress, to help the body respond appropriately, so high levels are a good indicator of this.

Although cortisol has an important role in driving your body's “fight-or-flight” instinct during a crisis, it also plays numerous other important roles on a daily basis. For example:

  • Managing the use of key nutrients like fats, proteins and carbohydrates
  • Controlling your sleep patterns
  • Regulating your blood pressure
  • Reducing inflammation
  • Increasing your blood sugar levels
  • Boosting energy levels to handle stressful events

Cortisol is produced in your adrenal glands, small organs at the top of your kidneys. The rate of cortisol production and release is carefully controlled by three different parts of the body communicating together. These are the pituitary gland, adrenal gland and the hypothalamus.

What If Cortisol Test Levels Are High?

What If Cortisol Test Levels Are High?

Physical and emotional stress can increase cortisol levels. When you are ill levels are also increased in response. Obesity, pregnancy and a number of drugs - particularly oral contraceptives - can also increase concentration within the bloodstream.

Since there are a number of conditions including hyperthyroidism or Cushing's syndrome that also increase cortisol concentrations, further investigation with your G.P. is recommended.

What If Cortisol Test Levels Are Low?

What If Cortisol Test Levels Are Low?

Low blood cortisol levels can be caused by a number of conditions including hypothyroidism and certain drugs including some steroid hormones.

It can also result from Addison's disease, a condition where the adrenal glands stop producing sufficient amounts of the hormones cortisol and aldosterone. This can develop very slowly and also has very common non-specific symptoms such as fatigue, weight loss or nausea, so can be difficult to identify.

Where cortisol levels remain low then further investigation is required to determine the cause.
