Laboratories for sleep-related breathing disorders are accredited by the AASM and are required to follow the "Code of Medical Ethics" of the American Medical Association. The new and very detailed "Standards for Accreditation" are available online. Sleep disorder centers, or clinics, are accredited by the same body, whether hospital-based, university-based or "freestanding"; they are required to provide testing and treatment for "all" sleep disorders and to have on staff a sleep specialist who has been certified by the American Board of Sleep Medicine and otherwise meet similar standards.
