Adrenal Stress Hormone Testing

The adrenal glands, otherwise known as the “stress glands,” enable our bodies to cope with stress and survive. Shaped like two tiny pyramids, they sit atop the kidneys and from this central location mobilize the response to changes in our environment.

Whether stress comes from outside in the form of a natural disaster, or from within like the anxiety we experience before public speaking, it’s the adrenals’ job to help us adapt to the situation.

They accomplish this by secreting key hormones:

Cortisol:
The primary stress hormone that fine-tunes our response to the stress of everyday living


DHEA:
One of the most abundant hormones in the body, and a precursor to estrogens and testosterone; also balances some of the negative effects of high cortisol


Epinephrine / Norepinephrine:
Neurotransmitters that mobilize the body’s natural “fight or flight” response in an emergency

Patients can conduct a saliva cortisol test or a urine cortisol test to assess adrenal hormones. This involves collecting four non-invasive samples over the course of one day, from which ZRT is able to generate results with a diurnal cortisol curve. This four-point graph reveals cortisol levels throughout the day and allows health care providers to pinpoint issues with adrenal gland function.

Diurnal cortisol curves – Key to understanding stress, fatigue & insomnia

Adrenal glands that are in balance produce adequate amounts of hormones to power us through the day. These hormones impact just about every process in the body, from energy production and immune activity to cellular maintenance and repair. They are key regulators of glucose, insulin and inflammation, and play a major role in bone and muscle building, mood and mental focus, stamina, sex drive and sleep cycles.

Adrenal glands that are out of balance can lead to:

High Cortisol

Results in insomnia, anxiety, sugar cravings, feeling tired but wired, increased belly fat & bone loss

Low Cortisol

Causes chronic fatigue, low energy, food and sugar cravings, poor exercise tolerance or recovery & low immune reserves

DHEA

Out of balance adrenals can lead to high or low DHEA.

Ideal Ways to Assess Adrenal Hormones

Saliva testing has long been used as an accurate and reliable method for measuring cortisol because it’s simple and non-invasive, and patients can collect these samples multiple times per day. It’s easy to assess DHEA in these samples too.

A newer method that’s just as reliable as saliva testing has also been gaining ground – dried urine testing. Studies show that urine is just as effective for measuring cortisol and DHEA levels, and it’s also simple enough for patients to collect multiple times per day.

The added benefit to dried urine testing is that epinephrine and norepinephrine can be measured at the same time, so patients who want a complete adrenal assessment can now get all four key markers together.
