By testing the levels of these elements together, ZRT can create a profile for the donor, which gives a more complete picture of the elements that affect sleep balance beyond testing a single element or hormone level. Testing multiple element and hormone levels at once is also more convenient and less expensive than testing single levels.
Hormone Imbalance Can Adversely Affect Sleep
Why test for these hormones and elements?
Cortisol/Cortisone: These are the hormones released by our bodies in response to stress. Chronically elevated levels are known to impair one's ability to sleep. By checking cortisol & cortisone levels at various time points, you can check to see if you're levels are in a constant state of elevation.
Melatonin: Melatonin is known as the sleep hormone and when melatonin levels are high, cortisol levels should be low and vice-versa. The gradual decline in production of the sleep hormone melatonin as we age triggers imbalances directly related to sleeping.

The graph shows the typical circadian variation in urinary melatonin and cortisol levels (Source ZRT). Melatonin production is greatest during the nighttime hours, resulting in a peak urinary MT6s early in the morning. Melatonin is gradually suppressed during daylight hours and rises during the evening towards bedtime. In an opposing pattern, night-time cortisol production is at its lowest; it is normally at its highest immediately after waking, peaking in the urine around 2 hours later. Cortisol levels drop towards the end of the day, with progressively lower levels in the evening as the night-time nadir is approached.
