Low levels of Testosterone, DHEA-S, and Cortisol together are indicative of chronically decreased adrenal function. And how to do saliva cortisol testing.

"How I Use the Saliva Hormone Tests

"I use the saliva hormone test to confirm other signs and symptoms of adrenal fatigue. I start with a saliva cortisol screening test that measures cortisol levels at four different times during the day: between 6:00-8:00 AM (within 1 hour after waking) when cortisol levels are highest; between 11:00- 12:00AM; between 4:00-6:00 PM; and between 10:00-12:00 PM. This shows how your cortisol levels vary during the day (something else you cannot easily do with blood or urine tests).

"In addition, if I have a patient whose main symptom is fatigue and their questionnaire is inconclusive, or if someone has intermittent symptoms, I use the saliva test to determine if their symptoms are related to low adrenal function. Sometimes I have patients carry around some test vials with them so they can take saliva samples while they are experiencing a low period or other symptoms, at any time during the day. On each saliva sample they write the date and time. They also record, along with the date and time, information on a separate sheet of paper and send the vials off to the lab. When I get their test results back, I compare their saliva cortisol levels with the laboratory standards for the time they are
experiencing symptoms. If the cortisol levels are low at those times, we know that low adrenal function is involved in the symptom picture. This gives me a way to assess adrenal activity at the time they were
experiencing a symptom.

"Another way I like to use the saliva test, when possible, is to compare samples taken when a patient is experiencing an energy high or low with samples taken during a regular day, when the patient is feeling relatively normal (baseline samples). After we have a baseline, these patients carry around some spare vials to take saliva samples at times when they are feeling especially good or especially bad. Again, they record the symptom(s) they were experiencing as well as the date and time (on a separate sheet of paper). They also record the date and time on each vial and send them off to the lab. This is an excellent way to determine whether the lows and highs you experience correspond to relatively low and high cortisol levels. To my knowledge, no other physician uses this method, but it is quite a handy method of determining cortisol levels in relation to symptoms.

"I also usually measure DHEA-S levels with the saliva test as well because the adrenals are the primary source of DHEA-S (but not necessarily DHEA). Adrenal fatigue syndrome often involves decreased DHEA-S. The DHEA-S level is a direct indicator of the functioning of the area within the adrenal glands that produces sex hormones (the zona reticularis). Saliva tests for testosterone, the estrogens, progesterone and other hormones can also be done, if needed, and may be of value in working with adrenal fatigue. Testosterone and DHEA-S levels are two of the most reliable indicators of biological age. Testosterone and DHEA-S levels below the reference range for the person’s age may be indicators
of increased aging. If the cortisol levels are also decreased, the 3 tests together further indicate chronically decreased adrenal function."
