** We would like to hear about other sleep labs who have knowledge about circadian rhythm disorders (CRDs) and are willing to accommodate their patient's schedule for the sleep study. ** If you would like to suggest a sleep lab for inclusion, please send (to ) the lab's contact information and any comments you wish to include to help us evaluate. (Your name and comments will remain private.) Thank you for helping others find a sleep lab.

Alternative to a Lab Study

Many clinics now offer sleep studies done at HOME, so you can do them at any time that works for you. It is also a lot less expensive than in a lab, $100 - $500 vs over $2,000, so may be an option for those without insurance coverage.
