It is worth confirming the referral rules first, since some practices require a GP letter and others do not. Confirm how payment works — up front, on the day, or billed afterwards — and whether insurance plans can be billed directly. Confirm whether the practice runs its own sleep laboratory or refers patients elsewhere for testing. Ask whether appointment confirmations and any forms can be sent before the visit. If telehealth is offered, ask which parts of the assessment can be done remotely and which need a visit. Ask who reviews the study results and when you will be told what they show. If you are travelling from another town, confirm parking, public transport and the exact entrance before the day. Treat the details here as a directory snapshot and confirm anything time-sensitive with the practice.
