The Circadian Phase Assessment saliva collection kit arrives with everything patients need to collect, handle, and transport saliva back to the Salimetrics CLIA-Certified Saliva Laboratory using a robust cold-chain managed collection, shipping and handling protocol for analyzing salivary melatonin samples for circadian rhythm profiling. There are no shipping costs or additional materials required. Once the collection kit is received patients are ready to complete the test.

Test Overview
These are the critical instructions patients need to follow in order to complete the test:
- Freeze the flask upon arrival
- Collect 7 or 9 small saliva samples over timed intervals, in a consistent, dim light environment
- Freeze samples in the flask after each collection
- Return the flask to the Salimetrics Clinical Laboratory for processing
Sample Collection Kit Component Overview
Sample Collection Instructions
The standard collection kit features highly detailed and robust sample collection instructions ensure that your patient’s samples are collected and stored according to the highest quality standards. Each assessment includes a standardized sample collection protocol, and also an option for custom scheduling so that you can fine-tune the collection protocol for complex cases. This provides flexibility when you would like to adjust the timing of your patient’s sample collection.
*9-Sample DLMO collection kit is only provided with an open sample collection schedule, to allow you the most flexibility in sample collection timing, whether you are capturing DLMO specifically or a diurnal melatonin profile.
Melatonin Sampling Form
The sampling form provides patients a space to log medications, supplements, and sample collection times, so that the melatonin profiles can be reliably calculated over time.
Sample Collection Devices
Each kit comes complete with SalivaBio’s gold-standard passive drool collection system, including Saliva Collection Aids and SalivaBio cryovials. This system has been validated by Salimetrics to provide the highest-quality passive drool samples without interference to endogenous melatonin levels and has been utilized by millions of participants in research studies worldwide.
Sample Shipping Flask and Refrigerant
Salimetrics tried-and-tested, no hassle, sample flask and refrigerant combination provides samples up to 3 full days of cooling power to keep samples stable during transit to the Salimetrics CLIA-Certified Saliva Laboratory. Freezing the whole flask in a standard household freezer and it’s ready to go.
