Test Specimen: Saliva
Test Analytes: : Melatonin x 3
The Melatonin Profile provides a snapshot of the sleep/wake cycle during a one day period. This profile is recommended for those experiencing sleep disturbances.
Many people are familiar with melatonin because of its influence on sleep. Healthy melatonin curves help positively influence the initiation and maintenance of quality sleep cycles, and disruptions in melatonin curves, commonly referred to as phase shifts, may present clinically as disordered sleep patterns.
Melatonin and cortisol share an inverse relationship – when melatonin levels are low, cortisol levels should be high and vice versa. However, just as it is possible to see disruptions in cortisol curves, disruptions in melatonin curves may be noted and are influenced by several factors. For instance, declines in melatonin levels are seen with age, blue light exposure (as commonly emitted by TV and computer screens), and some medications including benzodiazepines and antihypertensives (beta blockers). Some antidepressants and anti-psychotics may shift melatonin curves, as can strenuous exercise. Melatonin supplementation can be particularly useful for people who engage in shift work or are jet lagged.
