More about Cortisol

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.

How much Saliva is required for each [tube] sample collection for this test?

This test includes 4 sample collections, each of them requiring 5mil of saliva. Your collection vial/tube has indicators clearly marked to prevent any confusion. Included in the instructions are tips on producing saliva. These tips can also be found in the Q&A on this website.

I take medicines, how do I know they won't affect the results?

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.

How do I know the sample will not deteriorate in the mail?

The laboratory will not compromise themselves by testing saliva that is past its used by (too viscous). Their only concern is the accuracy of the results and the integrity of the laboratory. So when a sample turns up that has been delayed by Australia Post, and it isn't fit for testing, they have no hesitation in rejecting it, and we start the process over (at no cost to you).

More: The official position of saliva travel time is that saliva samples are good for (up to) 12 days, Despite the guidelines, each sample is assessed for suitability upon arrival prior to testing.

What are causes of cortisol irregularity?

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.
