Why Run this Test?

Knowing the timing of a patient’s nocturnal melatonin secretion reliably evaluates the sleep-wake cycle to determine alignment or misalignment (phase delay or phase advance) from a typical 24-hour entrained circadian clock. Temporal shifts on the phase response curve can indicate abnormal sleep-wake patterns and provide clinicians with important data for sleep disturbance assessment.
