What is an overnight sleep study?

A sleep study or nocturnal polysomnogram is a specialized test that a doctor orders to investigate whether a patient has a sleep disorder, such as insomnia, sleep apnea, narcolepsy or restless leg movements. Patients are required to sleep for a night within the supervised setting of the sleep lab while expert technologists monitor and record the quality of sleep enabling them to determine the nature of the sleep disorder.

The sleep study is interpreted and read by specialized technologists and physicians with training in sleep disorders. A specialist will review the sleep study report and give his/her interpretation of the results to the doctor. This sleep specialist provides suggestions for treatment and management to each patient’s physician.

Please note that a medical referral is mandatory.
