Diurnal Cortisol Home Health Test Kit - Saliva

Use the above tabs for extended information on this product.


Cortisol is a steroid hormone found in the glucocorticoid class of hormones. Produced within the adrenal gland, cortisol is often referred to as the "stress" hormone because it is released in response to stress and low blood-glucose. Cortisol increases blood sugar through a process called gluconeogenesis, that suppresses the immune system and help metabolises fat, protein, and carbohydrates. It also decreases bone formation.

Under stressful conditions, cortisol provides the body with glucose by tapping into protein stores through gluconeogenesis in the liver. This energy helps you engage the fight or flee response to a stressful condition. However, elevated cortisol levels over long periods of time cause the body to consistently produce glucose, leading to increased blood sugar levels. Elevated cortisol levels interfere with learning and memory, lower immune function and bone density, increase weight gain, blood pressure, cholesterol, heart disease and more.

Chronic stress and resulting elevated cortisol levels also increase your risk for depression, mental illness, and lower your life expectancy.

Your saliva samples will test: Cortisol (Cx4) levels at four times during the day.
