Special instructions

Do not eat or drink for 30 minutes before your test. Do not brush your teeth for 30 minutes before your test. Your result could be affected by corticosteroid medication (e.g. prednisolone). Ask your doctor whether you should stop before testing. HRT and the contraceptive pill can affect the results of this test, taking the test during a break from these will give more accurate results. Do not take biotin supplements for 2 days prior to this test. If you are taking prescribed biotin you should discuss this with your doctor.
Chronic stress can be very bad for our health and can lead to an impaired immune system as well as problems with energy levels, fat retention and sleep. Cortisol is a steroid hormone which is produced in the adrenal glands and is your body's main stress hormone. It is vital for survival given its role in various functions such as immunity, regulating blood pressure and releasing insulin for blood sugar maintenance. Cortisol has been termed 'the stress hormone' because it is secreted in higher quantities during the body's 'fight or flight' response to stress, and is responsible for several stress-related changes in the body.

This test measures the levels of cortisol in your saliva at 6 different points in the day. Samples are taken after waking, 12 noon, 2pm, 4pm, 6pm and before going to sleep. Cortisol levels should be highest just after waking in the morning and lowest at bedtime; this is called diurnal rhythm. This test will tell you whether your cortisol levels are normal for the time of day, or whether you need to be taking action to reduce the amount of stress in your day-to-day life. 

As well as helping you to see if you are experiencing too much stress, this test can also help identify medical conditions such as Cushing's syndrome, which is caused by too much cortisol, or Addison's disease, which is caused by damage to the adrenal glands and is associated with too little cortisol. 

Please note that the lower detection limit for this test is 1.5 nmol/L.
