Testing at a Glance
Where Are You in the Process?
I Am Reviewing Possible Symptoms
Start with signs, risk factors and the Online Sleep Test.
Confirming Sleep Apnea
Symptoms and Questionnaires Cannot Provide a Diagnosis
Snoring, breathing pauses and daytime sleepiness may raise concern. An online assessment can help organize symptoms and risk factors, but neither symptoms nor questionnaires determine whether sleep apnea is present.
Testing records information while the person is asleep. The results are interpreted alongside health history and the wider clinical situation.
Sleep Testing Can Help Determine
- Whether breathing events were recorded
- How frequently events occurred
- Whether oxygen levels changed
- Whether events varied with sleeping position
- Whether further assessment is needed
- Which treatment pathway may be considered
The interpreting healthcare professional—not the testing equipment alone—determines what the findings mean for the individual.
What to Expect
From Initial Concern to the Next Step
Sleep apnea testing usually follows a clear sequence from initial concern to professional interpretation.
01
Possible Signs Are Identified
The person, a partner or a healthcare professional notices symptoms or risk factors.
02
The Situation Is Reviewed
Sleep concerns, health history and relevant clinical information are considered.
03
A Test Is Selected
Home testing or an in-lab study may be recommended based on the individual situation.
04
Sleep Data Are Recorded
The assigned equipment collects information while the person sleeps.
05
Results Are Interpreted
The findings are reviewed and may lead to treatment, additional testing or another recommendation.
A test should not be selected solely because one option appears easier or more convenient.
Testing Options
Two Different Testing Environments
Home and in-lab studies serve different purposes and record different levels of information.
Home Sleep Apnea Test
- Completed in the person’s usual sleeping environment
- Uses portable monitoring equipment
- Records a focused set of breathing-related signals
- Equipment is usually applied by the patient using instructions
- May be appropriate for selected adults with suspected obstructive sleep apnea
- Results require professional review
In-Lab Polysomnography
- Completed overnight in a sleep laboratory
- Attended by trained staff
- Uses more extensive sensors
- Records sleep stages and multiple body systems
- Can evaluate more complex sleep concerns
- May be recommended after an inconclusive home test
Selecting the Appropriate Test
The Right Test Depends on More Than Personal Preference
The testing decision may consider reported symptoms, the likelihood of obstructive sleep apnea, other medical conditions, other possible sleep disorders and previous testing.
The ability to correctly use portable equipment, along with referral, provincial and insurance requirements, may also affect the pathway.
Home Testing May Be Considered When
- Obstructive sleep apnea is the main concern
- The adult patient is suitable for portable testing
- The required equipment can be used correctly
- The applicable clinical pathway approves home testing
In-Lab Testing May Be Preferred When
- The sleep concern is more complex
- Another sleep disorder may be present
- More extensive monitoring is required
- A home test was negative, inconclusive or technically inadequate
One method is not universally better than the other. The appropriate choice depends on the individual situation and clinical pathway.
Understanding the Equipment
Different Tests Record Different Types of Information
The exact signals recorded depend on the test equipment and testing protocol.
Airflow
Measures air moving through the nose or mouth.
Breathing Effort
Belts or other sensors may record chest and abdominal movement.
Oxygen Saturation
A finger sensor estimates oxygen levels during the recorded period.
Heart Rate and Rhythm
Some tests record pulse or more detailed cardiac information.
Sleep Position and Movement
Some equipment records body position, movement or snoring.
Sleep Stages
In-lab polysomnography may use brain, eye and muscle sensors to determine sleep stages.
Portable testing generally records a focused set of breathing-related signals, while in-lab testing records a broader set of sleep and body signals.
Before the Test
Follow the Instructions Provided for Your Assigned Study
Preparation details vary by test and provider, so the directions supplied for the specific study should take priority.
Confirm the Instructions
- Review arrival, pickup or return details
- Confirm which equipment will be used
- Ask what to do if a sensor disconnects
- Complete required forms or sleep diaries
Discuss Medications and Routine
- Provide an accurate medication list
- Follow instructions about medications
- Ask about caffeine, alcohol or naps
- Do not independently stop prescribed medication
Prepare for Sensor Placement
- Follow bathing and skin-preparation instructions
- Avoid products that interfere with sensors when directed
- Wear suitable sleep clothing
- Bring requested personal or medical items
Instructions vary. The directions supplied for the specific test should take priority over general website guidance.
Testing at Home
Portable Equipment Records Information While You Sleep
1. Receive the Test Equipment
Review the supplied equipment and instructions.
2. Apply the Sensors
Place the sensors before going to sleep as directed.
3. Start the Recording
Begin the recording using the supplied process.
4. Sleep With the Equipment
Use the equipment for the required recording period.
5. Return the Equipment
Return or submit the equipment according to the instructions.
A Home Test May Include
- A small recording device
- A nasal airflow sensor
- Chest or abdominal effort sensors
- A finger oxygen sensor
- A pulse sensor
- A position or snoring sensor
An Attended Overnight Study
- Arrival at the sleep laboratory
- Review of forms and instructions
- Sensor placement by a technologist
- Testing of the sensor signals
- Overnight recording in a private room
- Monitoring from a separate control area
- Sensor removal in the morning
In-Lab Polysomnography
More Extensive Monitoring Provides a Detailed View of Sleep
Sensors are attached to the head and body. Elastic belts may measure breathing effort, and a finger or ear sensor may measure oxygen.
A technologist monitors recording quality from a separate area. Sleeping differently from normal does not automatically make the study unusable, and some studies may include additional procedures when planned in advance.
After Testing
Recorded Data Must Be Reviewed Before Conclusions Are Reached
The recorded signals are checked, scored and interpreted before the next step is recommended.
Equipment Is Returned or Removed
Home equipment is returned as instructed, while laboratory sensors are removed after the study.
Recording Quality Is Checked
The test is reviewed to determine whether enough usable data were recorded.
Events Are Identified
Breathing events, oxygen changes and other recorded signals are assessed.
Results Are Interpreted
The appropriate professional considers the report and clinical context before recommending the next step.
No additional action
Repeat home testing
In-lab polysomnography

Reading the Report
Common Terms You May See After Testing
These definitions are introductory and do not replace individual interpretation by the appropriate healthcare professional.
Apnea
A recorded interruption or near-complete reduction in airflow that meets the applicable scoring criteria.
Hypopnea
A partial reduction in airflow associated with other qualifying changes.
AHI
The apnea-hypopnea index generally describes the number of qualifying breathing events per hour of sleep.
REI
The respiratory event index commonly summarizes qualifying events using the monitored or recording period in a home test.
Oxygen Saturation
An estimate of the oxygen level recorded during testing.
Oxygen Desaturation
A decrease in the recorded oxygen saturation level.
Do not use one report number by itself to select treatment or change prescribed therapy. Report definitions, scoring rules and severity classifications require professional interpretation.
When the Answer Is Not Clear
One Test Does Not Always Complete the Evaluation
A home or in-lab test may not provide a clear answer when sensors disconnect, too little usable recording time is collected or the test does not record enough information.
Additional testing may also be considered when the result does not match the symptoms or when another sleep disorder remains possible.
The Next Step May Include
- Repeating the home test
- Reviewing how the sensors were applied
- Completing an in-lab study
- Investigating another sleep concern
- Discussing ongoing symptoms with the healthcare team
A negative home result should not be interpreted as a guarantee that sleep apnea is absent.

Common Testing Questions
Quick Answers About Sleep Apnea Testing
Open a question below or visit the complete Sleep Apnea FAQ.
Can an online assessment diagnose sleep apnea?
No. An online assessment can help organize symptoms and risk factors, but diagnosis requires an appropriate sleep test and professional interpretation.
Is a home sleep apnea test the same as a sleep study?
A home sleep apnea test is one type of sleep study. It records a focused set of signals at home, while in-lab polysomnography records a broader range of sleep and body signals.
Who decides whether I need a home or in-lab test?
The appropriate healthcare professional considers the symptoms, health history, possible sleep disorders and applicable clinical pathway.
What happens if I cannot sleep normally during the test?
Sleeping differently from usual does not automatically make a test unusable. The recorded data are checked to determine whether enough useful information was collected.
What happens if a sensor disconnects?
Follow the instructions provided with the equipment. The recording will be reviewed to determine whether enough usable data remain or whether the test needs to be repeated.
What happens if the home test is negative or inconclusive?
The next step may include repeating the home test, completing an in-lab study or reviewing other possible causes of the symptoms.
