Why use this test?
This test is used to identify abnormal cortisol output and provides a comprehensive assessment of the cortisol daily pattern. Results provided in both Chart and Graph form.
Cortisol is great when it is working for us but not so great when it isn’t. Healthy cortisol assists with our busy daily lifestyle and also when confronting stressful situations, which we all face from time to time. Issues arise when it malfunctions, which can be over or under production, or where levels are elevated at the time we are attempting to sleep.
Processes differ from state to state with advantages to each.

Cortisol is the body’s primary stress hormone. When the brain stimulates its release in response to physical or emotional stress, the adrenal glands secrete cortisol into the general circulation. Cortisol helps the body regulate blood sugar levels, blood pressure, inflammation, the immune system, memory formulation. It also has a controlling effect on the body’s salt and water balance. In women, cortisol also supports the developing fetus during pregnancy.

Generally speaking, hormone testing is fine to do when using medicines but there are exceptions. Any supplements used to mimic the effects of hormones, and any steroid based treatment will affect the results. HRT treatment will obviously affect (some) test results and it is this effect people look to measure. New medicines, or brands of old ones, become available every day, and there is no conclusive list of medicines which interfere with any kind of human sample analysis.
Heat, cold, infection, trauma, stress, exercise, obesity, and debilitating disease can influence cortisol levels. The hormone is secreted in a daily pattern and it this pattern that is measured with the Comprehensive Cortisol Test.
