Saliva Testing

A common way to assess adrenal hormones is by taking a diurnal cortisol curve saliva test.  The Diurnal Cortisol Cx4 Saliva Hormone Test, by ZRT Laboratory, is designed to measure the levels of the hormone cortisol, taken four times in a 24-hour period (morning, noon, evening, and bedtime). The adrenal gland produces the hormone cortisol in response to stress. Prolonged high cortisol production can lead to chronic fatigue, "adrenal burnout" and other health problems.
