Sleep Balance Profile Test
The industry’s most accurate sleep-wake cycle testing reveals whether hormones are your hidden barrier to restful sleep. Measures cortisol and melatonin in dried urine at 4 time points – providing a true 24-hour sleep-wake pattern.
Sleep Balance Profile
ZRT is the only laboratory offering testing for the circadian rhythm of melatonin in concert with cortisol and cortisone to assess sleep/wake cycle dysfunction. Circulating melatonin is efficiently hydroxylated and conjugated with sulfate in the liver to form its primary metabolite, 6-sulfatoxymelatonin (MT6s), and excreted into urine; it is this metabolite that is measured in the Sleep Balance Profile. Adrenal cortisol, produced in response to stress, is also known for its diurnal variation linked to the sleep/wake cycle. It has the opposite pattern to melatonin production in a healthy individual.
Sleep Balance Profile includes:
Dried Urine: Melatonin MT6s x4, Free Cortisol x4, Free Cortisone x4
Sleep Balance Profile allows physicians to pinpoint imbalances of melatonin and cortisol circadian rhythms associated with acute or chronic sleep disturbances.
Consider for: Patients with an inability to get to sleep, frequent waking, or chronic sleeplessness affecting vitality, cognition, weight, and diabetes / cardiovascular disease risks.
+ Optional Norepinephrine & Epinephrine Add-on: Gives a better picture when there are adrenal issues
