In-lab Sleep Test

In-lab Sleep Test: Effective and Flexible

There are over 80 sleep disorders and not all of them are well served by the simple home sleep test.


Our sleep lab is dedicated to diagnosing patients with sleep-related disorders. A polysomnography, or in-lab sleep test, is more accurate than a home sleep test, particularly in less typical cases of obstructive sleep apnea, where there may be an associated respiratory or cardiac disease. In-lab sleep tests are also key in diagnosing periodic leg movements, insomnia, narcolepsy and sleepwalking. At Apnée Santé, you will meet a sleep doctor to discuss the best test for your particular situation.

You may begin with a home sleep test, and if the results are inconclusive, the sleep specialist may suggest you take a polysomnography in our comfortable, state-of-the-art sleep lab.

If you require an in-lab sleep test, you have 2 choices:

    • You can be tested in our sleep lab and the cost of your home sleep test will be deducted from that of the full sleep study.
    • If your insurance does not cover a an overnight sleep study in a private lab, our sleep doctors can refer you to a public hospital and they can follow up with you after your test.

At Apnée Santé we provide you with choice and flexibility. All decisions are made by you and your sleep doctor. Call us for a free sleep assessment at 1-800-727-8748

What to expect during a polysomnography?

In-lab Sleep Test

8:30pm: Arrival at our sleep lab where you will be greeted by a respiratory therapist (aka sleep tech) who is trained in sleep technology.

8:30 – 10pm: You will change into sleepwear and the sleep tech will attach sensors to you in order to collect data on your brain activity, sleep stages, eye movements, heart rate, blood pressure, oxygen levels, body movement, and more. These sensors are non-invasive sensors and they are comfortable enough to allow you to sleep as you might at home — that is, you can change positions, roll over, go for a bathroom break etc.

5:30 am: The sleep tech will wake you up and carefully remove all the sensors. There is a shower, coffee, tea and water provided for you in the morning. NOTE: A technologist is ALWAYS available to provide you with assistance. He or she may on occasion enter your room to make some technical adjustments.

The following day your study will be scored and analyzed by our sleep tech, and the sleep doctor will interpret the study. You’ll meet the sleep doctor within 2 weeks of your test.
