24-HR Circadian Rhythm Test (Circadian Phase Map), 9-Sample

*Currently Unavailable in New York State*

A 24-Hour Melatonin Circadian Phase Map, measured in saliva, maps the biological night, a state of entirely different physiology from the wake state. A full 24-hour Circadian Phase Map can provide useful physiologic information to help assess an individual’s biological night in relation to circadian timing and sleep function for complex issues where an individual may be suffering from multiple sleep disruptions or non-24-hour sleep-wake rhythm disorders. A circadian rhythm disorder is generally present when the relationship between the timing and duration of sleep and the circadian rhythm is significantly altered. Thus, the “biological night” can be too long, too short, unstable (varying with time), or misaligned – all of which can cause clinical symptoms and are also targets for treatment.

This Circadian Phase Assessment Kit offers an all-inclusive, easy and accurate way to measure your circadian phase through salivary melatonin testing in the convenience of your own home or at a sleep facility, without the need for a blood draw or overnight polysomnography. For a full phase map, you will collect 9 timed saliva samples over one day. Once samples are self-collected, freeze and send samples to Salimetrics’ CLIA-Certified testing facility using the pre-paid return shipper. Results are reported directly to your sleep specialist (if provided) and you through a secure, HIPAA compliant results portal within 7-14 business days. Results can then be used as valuable insight towards treatment for a better night’s sleep.
