The Adrenal Stress Index (ASI) test is used to determine the levels of the adrenal cortex hormones, cortisol and DHEA/DHEA-S, throughout the day. This information is important because appropriate production and release of these hormones is required for us to deal with the stresses of the day, from simply having the energy to get out of bed, to dealing with work and relationship stress, as well as the life and death situations which trigger the fight-or-flight-response.
This test is often used when people feel their ability to cope with stress has decreased or they are experiencing symptoms associated with adrenal fatigue such as:
- Fatigue
- Feeling Drained
- Hypoglycaemia/Blood Sugar Imbalance
- Dizziness Upon Standing
- Insomnia
- Not Feeling Rested on Waking
- Poor Stress Tolerance
- Depression
- Poor Exercise Tolerance
- Recurrent Infections
- Allergies
- Chemical Sensitivies
- Lack of Mental Alertness
The ASI test is also used in conditions such as chronic fatigue syndrome (ME/CFS) and fibromyalgia as studies have indicated that the adrenal glands and the mechanisms controlling them are often dysfunctional, resulting in low cortisol and DHEA production.
What the Adrenal Stress Index (ASI) Test Involves
The ASI is a simple inexpensive saliva test that can be carried out at home. It involves the collection of saliva samples in test tubes provided at specific times throughout the day. There are usually 4 or 6 sample collection times typically starting with the first at 6-8am and the last a midnight. You must not eat for a few hours before each sample to avoid contamination.
Once you have collected the samples you simply seal them in a prepaid envelope provided and mail them back to the lab.
Explanation
The lab will mail your results back to you, typically with graphs displaying your hormone levels throughout the day along with the numerical results. The lab may also provide interpretation of the results. It is best to discuss your results with your doctor or other health care provider however as interpretation and determination of appropriate treatment is complex. General hormone concentrations as well how they vary throughout the day (the circadian rhythm) and the relationship between cortisol and DHEA levels are all important factors to consider.
