DLMO, Dim Light Melatonin ONSET Test, 7 or 9 Sample


*Currently Unavailable in New York State*

Bedtime Sampling – Do you know when your body wants to go to sleep? Many of us work against our body’s natural sleep cycle, also known as a “circadian rhythm”. However, this simple circadian phase test can reveal the exact timing of your body’s natural circadian rhythm using saliva to determine your Dim Light Melatonin Onset (DLMO).

The Salimetrics Circadian Phase Assessment Kit for Dim Light Melatonin Onset (DLMO test) 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. This simply requires the collection of 7 or 9 timed saliva samples over one evening. Once samples are self-collected, you will freeze them in our cold-chain managed shipping flask, and then use the pre-paid return shipper to send your samples to Salimetrics’ CLIA-Certified testing facility. Results are reported directly to your sleep specialist (if provided) or back to you through a secure, HIPAA compliant results portal within 7-14 business days. Results can then be used as the next step towards treatment for a better night’s sleep.

The National Institutes of Health estimates that 50 to 70 million Americans have chronic sleep disorders and intermittent sleep problems. Likewise, a poll conducted by the National Sleep Foundation indicates that 70% of Americans say they have frequent sleep problems. Due to costly, unpleasant testing procedures, most sleep problems remain undiagnosed and untreated in the US. However, this DLMO test can help. When properly diagnosed and treated, sleep specialists estimate that 85-90% of their patients get better sleep.
