Quick answer
A home sleep study is an overnight test done at home to check for possible obstructive sleep apnoea by recording breathing-related signals such as airflow, oxygen levels and breathing effort. In Singapore, it is often a suitable first test for adults with snoring, witnessed pauses or daytime sleepiness, but a doctor or sleep physician should review the results because home testing does not assess every sleep disorder.

Key takeaways
-
A home sleep study is mainly used to assess suspected obstructive sleep apnoea in adults and commonly measures airflow, oxygen saturation, breathing effort and sometimes body position over 1 night.
-
In Singapore, Type 3 home sleep tests are available on demand, while Type 2 home sleep tests are arranged manually with a trained specialist when a more involved home setup is needed.
-
AHI 5 to 14.9 is generally mild OSA, 15 to 29.9 is moderate, and 30 or more is severe, but doctors also consider symptoms, oxygen desaturation and medical history.
-
Home testing is more convenient than in-lab polysomnography, but it uses fewer signals and may miss milder OSA, central events or non-breathing sleep disorders.

What Is a Home Sleep Study?
A home sleep study is an overnight sleep test done at home to check for signs of sleep-disordered breathing, especially obstructive sleep apnoea. A home sleep test records breathing-focused signals while you sleep in your usual environment.
The purpose of a home sleep study is to give a doctor or sleep physician useful data, not to replace medical assessment. The recording can show airflow changes, breathing effort, oxygen desaturation and event patterns that may suggest OSA.
A home sleep study is often considered when an adult has symptoms or risk factors that make OSA more likely. It is usually simpler than in-lab polysomnography because the device uses fewer sensors and focuses on breathing rather than full sleep staging.
If you want an overview of local options, Comooz explains its home sleep test service in Singapore.
Why Sleep Apnoea Matters: Symptoms, Risks and Who Should Get Checked
Sleep apnoea matters because repeated airway collapse can fragment sleep and lower oxygen levels overnight. Untreated obstructive sleep apnoea can affect daytime functioning and may matter for broader cardiometabolic health.
Common symptoms include loud snoring, witnessed pauses in breathing, choking or gasping during sleep, unrefreshing sleep, morning headaches and daytime sleepiness. Some people also notice poor concentration, irritability or sleepiness at work.
A home sleep study is more likely to be useful for adults with a strong suspicion of uncomplicated OSA. It is less suitable when the main concern is another sleep disorder or when symptoms are complex.
Who a home sleep study is for
A home sleep study is often a reasonable first step for adults who:
-
snore loudly and regularly
-
have witnessed breathing pauses
-
wake choking or gasping
-
feel sleepy in the daytime
-
have risk factors such as higher body weight, hypertension or type 2 diabetes
Who a home sleep study may not be for
A home sleep study may be less suitable if a doctor suspects:
-
parasomnias
-
movement disorders
-
narcolepsy
-
complex breathing disorders
-
symptoms that need full in-lab polysomnography and CPAP titration
Comooz, a Singapore CPAP provider (UEN 201808754M), also publishes general education in its sleep apnoea learning centre.
How a Home Sleep Study Works in Singapore
In Singapore, a home sleep study usually involves assessment, equipment setup, one night of recording at home and professional review afterward. The exact pathway depends on whether a Type 3 or Type 2 home sleep test is used.
A Type 3 home sleep test is a portable breathing-focused study commonly used for suspected OSA. A Type 2 home sleep test is more involved and is arranged manually with a trained specialist.
1. Clinical assessment
A doctor or sleep specialist reviews your symptoms, health history and suitability for a home sleep study. This step matters because home testing is not the right test for every patient.
2. Device setup and instruction
You are shown how to place the sensors correctly before the test night. Depending on the system, sensors may include airflow measurement, an oximeter, breathing effort belts and body-position monitoring.
3. Overnight recording at home
You sleep at home with the device for the arranged night. The test aims to capture typical breathing patterns, snoring-related airflow changes and oxygen desaturation events.
4. Data review and reporting
After the test, the recording is downloaded and interpreted. The report may include respiratory event counts, oxygen trends and an estimated AHI.
5. Follow-up and next steps
A doctor or sleep physician explains what the result means and whether follow-up, repeat testing, in-lab polysomnography, CPAP discussion or other treatment planning is appropriate.
Type 2 vs Type 3 Home Sleep Study: What’s the Difference?
Type 3 and Type 2 home sleep studies both assess sleep-disordered breathing, but they differ in complexity and setup. In practice, Type 3 is the more common on-demand option for suspected uncomplicated OSA.
| Feature | Type 3 home sleep test | Type 2 home sleep test |
|---|---|---|
| Main use | Suspected uncomplicated OSA | More detailed home-based assessment when clinically indicated |
| Availability at Comooz | Available on demand | Arranged manually with a trained specialist |
| Signals | Breathing-focused signals such as airflow, oxygen and effort | More involved setup than Type 3 |
| Convenience | Higher convenience | Lower convenience than Type 3 |
| Best for | Adults with straightforward OSA symptoms | Selected cases needing a more involved home study |
| Interpretation | Requires doctor or sleep physician review | Requires doctor or sleep physician review |
The right choice depends on the clinical question, not just convenience. If the concern is straightforward suspected OSA, a Type 3 home sleep study is often the first option discussed.
Home Sleep Study vs In-Lab Sleep Study
A home sleep study is more convenient, while an in-lab sleep study measures more signals and can evaluate a wider range of sleep problems. The right test depends on the symptoms, the likelihood of OSA and whether more detailed information is needed.
| Feature | Home Sleep Study | In-Lab Sleep Study |
|---|---|---|
| Where the test is done | At home in your usual sleep environment | In a sleep lab or hospital setting |
| Signals measured | Usually breathing-focused signals such as airflow, oxygen levels, breathing effort and sometimes body position | Broader polysomnography signals including brain activity, eye movements, muscle activity, airflow, oxygen and more |
| Who it suits | Adults with suspected uncomplicated obstructive sleep apnoea | People with complex symptoms, unclear results, other suspected sleep disorders, or when more detail is needed |
| Convenience | Higher convenience and familiar environment | Less convenient because you sleep in a monitored facility |
| Limitations | Fewer signals, may miss milder OSA or non-breathing sleep disorders | More complete but requires lab attendance |
| Typical next steps | Clinical review, possible repeat testing, in-lab study or CPAP discussion | Diagnosis clarification, treatment planning, CPAP titration or specialist follow-up |
The key difference is that home sleep testing is targeted and practical, while lab testing is broader and more detailed. In-lab studies are also where formal polysomnography and some CPAP titration decisions are more likely to happen.
What a Home Sleep Study Measures and What It Can Miss
A home sleep study measures breathing-related signals that help estimate whether sleep apnoea may be present. It is designed for breathing assessment, not for every sleep complaint.
Most home sleep tests measure some combination of:
-
nasal airflow
-
oxygen saturation and oxygen desaturation
-
breathing effort
-
heart rate
-
snoring-related vibration or sound
-
body position, depending on the device
These measurements help identify apnoeas, hypopnoeas and patterns suggestive of OSA. The report may estimate an AHI and show whether meaningful oxygen drops occurred overnight.
A home sleep study can miss things because it does not capture the full signal set of polysomnography. That means it may be less useful when the concern is not mainly obstructive sleep apnoea.
What it usually does not measure fully
Home sleep studies usually do not provide the same detail on:
-
sleep stages
-
brain-wave activity
-
eye movements
-
muscle activity
-
some non-breathing sleep disorders
If symptoms strongly suggest sleep apnoea but the home sleep study is negative or unclear, a doctor may advise a lab study instead.
Understanding Results: AHI, Severity Ranges and What Happens Next
AHI is the number most patients look for after a home sleep study. AHI stands for apnoea-hypopnoea index, which estimates how often breathing pauses or partial reductions happen per hour.
| AHI range | Usual interpretation |
|---|---|
| Below 5 | Often considered within normal range |
| 5 to 14.9 | Mild obstructive sleep apnoea |
| 15 to 29.9 | Moderate obstructive sleep apnoea |
| 30 or more | Severe obstructive sleep apnoea |
AHI does not tell the whole story. Doctors also consider oxygen desaturation, symptoms, medical conditions and whether the result matches the clinical picture.
What happens after the report
Possible next steps after a home sleep study include:
-
reassurance and monitoring
-
discussion of sleep habits and risk factors
-
referral to a sleep specialist
-
in-lab polysomnography if the result is unclear
-
treatment discussion if OSA appears clinically significant
If treatment is needed, CPAP is one common option. Auto-adjusting CPAP such as a ResMed AutoSet machine may be discussed, while some patients with more specific pressure needs may require formal titration or, less commonly, bilevel support where EPAP and inspiratory pressure are set differently by a clinician.
Accuracy, Safety and Limitations to Know
A home sleep study can be accurate enough for many adults with suspected obstructive sleep apnoea, but it has limits. The main trade-off is convenience versus signal depth.
Accuracy depends on choosing the right patient and getting good signal quality. Poor cannula placement, a loose effort belt or a dislodged oximeter can reduce the usefulness of the recording.
A negative test does not always rule out OSA when symptoms are strong. If the history still suggests sleep apnoea, a doctor may recommend repeating the test or proceeding to in-lab polysomnography.
A home sleep study should always be arranged and interpreted with clinical oversight. It is a tool that informs diagnosis and treatment planning; it is not a stand-alone diagnosis.
Costs in Singapore and When CPAP May Be Discussed
Home sleep study costs in Singapore vary by provider, test type and whether specialist review is included. Before booking, confirm what is included, who interprets the study and what follow-up happens after the report.
If a doctor later recommends CPAP after your home sleep study, these are Comooz’s current reference bundle prices:
| CPAP option | Bundle price in Singapore | Included | Best fit summary |
|---|---|---|---|
| ResMed AirSense 11 AutoSet Bundle | $2,068 nett | Main unit, power supply, built-in humidification, tubing, filter, carrying case and a fitted mask | People who want a newer interface, full-colour touchscreen, Climate Control and over-the-air updates |
| ResMed AirSense 10 AutoSet Bundle | $1,868 nett | Main unit, power supply, built-in humidification, tubing, filter, carrying case and a fitted mask | People who want a proven workhorse design with dial control and built-in cellular connectivity for myAir |
The AirSense 11 AutoSet has a full-colour touchscreen, Climate Control with integrated humidification, over-the-air updates and Care Check-in. The AirSense 10 AutoSet uses a monochrome display with dial, integrated HumidAir chamber and built-in cellular connectivity for the myAir app.

Trial and rental policies
Comooz also states that its 5-night CPAP trial is not free. The trial involves a deposit, mask cost and a $98 return fee.
CPAP rental is monthly, with 3-month offset rules toward purchase. Ask for the exact current rental structure and how any offset applies before committing.
CPAP mask choice after a home sleep study
If a home sleep study leads to CPAP, mask choice matters as much as machine choice. The best mask depends on whether you breathe mainly through your nose, whether you move a lot in sleep and whether you need a more minimal or more secure seal.
Nasal pillow vs nasal cradle vs full face
Nasal pillows sit at the nostrils and feel minimal. Nasal cradle masks sit under the nose. Full face masks cover the nose and mouth and are often considered when mouth breathing is significant.
| Mask style | Best fit for | Trade-off | Example discussed |
|---|---|---|---|
| Nasal pillows | People wanting a light, minimal mask | May not suit everyone at higher pressures | ResMed AirFit P30i or AirFit P10 |
| Nasal cradle | People wanting under-the-nose comfort | Needs a good seal around the nose base | ResMed AirFit N30i or AirFit N30 |
| Full face | Mouth breathers or people with frequent nasal blockage | Bulkier than nasal-only options | ResMed AirFit F20, AirTouch F20 or AirFit F30i |
People who mainly breathe through the nose often start with a nasal interface. People with persistent mouth leak, frequent nasal blockage or a preference for mouth breathing may do better with a full face mask.
Comooz can help with fitted mask selection by appointment. Common examples include nasal pillow masks, nasal masks and full face masks, but the right option should follow assessment and fitting rather than guesswork.

A home sleep study is useful when you want a convenient first step for suspected obstructive sleep apnoea, but it is not a replacement for a doctor’s diagnosis or treatment plan.
Frequently asked questions
What is a home sleep study used for?
A home sleep study is mainly used to assess whether obstructive sleep apnoea may be present in adults with symptoms such as loud snoring, witnessed pauses in breathing, choking during sleep or daytime sleepiness. It helps doctors decide whether further testing or treatment should be considered, but it does not replace clinical review.
Is a home sleep study accurate enough?
For many adults with suspected obstructive sleep apnoea and no major complicating features, a home sleep study can be a useful first test. However, it measures fewer signals than a lab study, so it may miss milder cases or other sleep disorders. Results should always be interpreted by a doctor or sleep physician.
Can a home sleep study diagnose all sleep problems?
No. A home sleep study is designed mainly for breathing-related sleep disorders, especially obstructive sleep apnoea. It is not the best test for every condition, including some movement disorders, parasomnias, narcolepsy or more complex breathing issues. If symptoms do not match the result, a doctor may suggest in-lab polysomnography.
How do I prepare for a home sleep study?
You will usually be shown how to place the sensors before taking the device home. Try to follow your usual sleep routine and apply the equipment exactly as instructed. Good sensor placement matters because loose belts, a displaced airflow cannula or a detached oximeter can reduce recording quality. Avoid changing your routine just to “sleep better” for the test.
What do AHI numbers mean?
AHI stands for apnoea-hypopnoea index, which estimates how often breathing reductions or pauses happen per hour. In general, 5 to 14.9 is mild, 15 to 29.9 is moderate and 30 or more is severe. Doctors also consider symptoms, oxygen desaturation and overall health, not just the AHI number alone.
How much does treatment cost if sleep apnoea is confirmed?
If a doctor recommends CPAP after assessment, pricing depends on the machine package and whether you trial or rent first. Current reference prices at Comooz are $2,068 nett for the ResMed AirSense 11 AutoSet Bundle and $1,868 nett for the ResMed AirSense 10 AutoSet Bundle. The 5-night CPAP trial is not free and includes a deposit, mask cost and a $98 return fee.
