How long will it take to get the results after a sleep study is conducted? Dr. McPherson: Sleep studies, after they are completed they are scored by a technologist, which can take a period of one to four days, and then they are subsequently interpreted by a physician, which can take another one to four days. So for most sleep labs, the results are available within four to seven days and at the latest, two weeks in some sleep labs. So it’s somewhat variable. But usually within a week the sleep lab results are available to the patient and the doctor, the referring doctor.
