Diagnosis
Diagnosis of OSA is often based on a combination of patient history and tests (lab- or home-based). These tests range, in decreasing order of cost, complexity and tethering of the patient (number and type of channels of data recorded), from lab-attended full polysomnography ("sleep study") down to single-channel home recording. In the USA, these categories are associated with insurance classification from Type I down to Type IV. Reimbursement rules vary among European countries.
