The analytical determination of the DLMO is based on a partial, 5 point salivary melatonin profile. The client is provided with a collection pack containing five saliva collection devices together with the appropriate instructions enabling the client to collect the samples at home. The samples are collected at hourly intervals around the normal sleep time, over the course of one evening. The samples will be sent to the specified in-vitro diagnostic routine laboratory where melatonin concentrations are determined and the individual DLMO is determined.

The Sleep Check Collection Pack can be supplied directly by a Medical Health Specialist (sleep specialist, neurologist etc.) during a face-to-face consultation or could be requested directly by the client via internet facilities. The client could also retrieve results directly from the internet for discussion with the sleep specialist depending on the Sleep Center offering the service.

You can check in our instructions for use how to proceed properly.
