Description: While commonly performed by patients in sleep clinics for many years, the at-home option for patients to perform saliva collections at home is a reality now for clinicians assessing circadian rhythm disorders. Patients are required to restrict certain foods and activities on the day of collection. The start time of the 8 hourly saliva collections starts 5 hours previous to the typical time of falling asleep. Restriction of light to > 30 lux is critical to a successful collection procedure, given that excess light will suppress melatonin. The patient stays awake for the entire collection process, freezes the samples, then ships them to the lab in a thermal container. Device apps like multi-timers and light meters can be downloaded to ensure compliance.
