When you call, ask what referral paperwork is required and whether a GP letter must arrive before the visit. Ask what is billed separately, such as the study, the report, or a follow-up appointment. Ask what kind of sleep study is offered, where it takes place, and whether you sleep there overnight. Ask what to bring: a medication list, any referral letter, a sleep diary, and results from earlier studies. If you need an interpreter, ask whether one can be arranged for the appointment. Ask who reviews the study results and when you will be told what they show. If the practice sits inside a larger medical center, ask which building and floor to go to. Confirm fees, availability and location directly with the practice, as directory listings are not updated in real time.
