Ask how the study is arranged, how long the wait is for a test date, and when the results are discussed. 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. It is worth asking whether the practice deals with the kind of sleep problem you have, since some clinics focus on particular conditions.
