LOINC description : Melatonin assays are used to evaluate the phase position of the biological clock and alignment of an individual's circadian rhythm with a typical 24-hour sleep-wake cycle. Saliva melatonin levels are relatively unaffected by changes in posture and at any given time, the saliva concentration is approximately 30% of that in the plasma. Given that saliva sampling is noninvasive and painless, saliva provides a convenient alternative to plasma. Timed melatonin measurement is used to identify sleep-wake cycle disorders, and melatonin can also be used to determine pineal gland function and help in the diagnosis of pineal tumors.
