Quick answer
A **sleep test** measures breathing and related signals overnight to help a doctor assess suspected sleep apnoea and other sleep-breathing problems. In Singapore, the main options are a **home sleep test** or in-lab **polysomnography**. Home tests are simpler and breathing-focused; lab studies are more detailed and are used when symptoms, medical history, or the diagnostic question are more complex.

What is a sleep test?
A sleep test is an overnight assessment that records breathing and other body signals during sleep. Doctors use a sleep test to investigate suspected sleep-disordered breathing, especially snoring with pauses in breathing, oxygen desaturation, and daytime sleepiness.
The term sleep test is broad. It can mean a home sleep test done outside a hospital, or a more detailed in-lab polysomnography that captures additional channels such as brain waves, eye movements, muscle activity, and sleep stages.
A home sleep test is mainly for breathing-related assessment. Polysomnography is more detailed and is often chosen when a doctor needs to assess more than suspected uncomplicated obstructive sleep apnoea.
For broader background, Comooz publishes educational resources in its sleep health learning centre.
Why someone in Singapore might need a sleep test
A sleep test is usually considered when symptoms suggest disrupted breathing during sleep or another clinically important sleep problem. The purpose is to gather objective overnight data rather than rely on snoring or tiredness alone.
Common triggers include loud habitual snoring, witnessed pauses in breathing, choking or gasping during sleep, unrefreshing sleep, morning headaches, and excessive daytime sleepiness. Some people seek testing because a partner notices repeated breathing pauses or restless sleep.
In Singapore, people often first discuss these symptoms with a GP, sleep physician, ENT doctor, or another treating doctor. That clinician decides whether a sleep test is appropriate, which type to use, and whether other heart, lung, neurological, or ENT issues should be assessed.
Who this is for and who it is not for
A sleep test is most relevant for people with symptoms or risk factors that point to sleep-disordered breathing. It is especially relevant when symptoms affect safety, concentration, work, or driving.
A sleep test may be particularly worth discussing if you have loud snoring plus witnessed apnoeas, significant daytime sleepiness, resistant hypertension, or repeated morning headaches. It is also relevant if you have already been told you may need CPAP titration or further assessment before treatment.
A sleep test is not a DIY diagnosis tool. If symptoms are complex, if central events are a concern, or if other medical conditions are involved, a doctor may prefer specialist review and a more detailed polysomnography instead of starting with a simpler home study.
What conditions a sleep test can help assess
A sleep test helps doctors assess breathing-related sleep disorders, especially obstructive sleep apnoea (OSA). It can also provide useful data when symptoms raise questions about other forms of disturbed breathing during sleep.
OSA happens when the upper airway narrows or collapses during sleep, reducing or stopping airflow. This can lead to repeated apnoea or hypopnoea events, oxygen desaturation, snoring, and fragmented sleep.
Depending on the type of sleep test, doctors may assess:
-
Repeated oxygen drops during sleep
-
Patterns linked to body position
-
Possible differences between REM and non-REM sleep in lab studies
-
Whether event patterns look more obstructive or raise questions about central events
A sleep test supports medical assessment; it does not replace it. Doctors interpret results alongside symptoms, examination findings, and medical history before making treatment recommendations.
Home sleep test vs lab sleep study: what’s the difference?
A home sleep test is a simplified overnight test that mainly measures breathing-related signals. A lab sleep study, or polysomnography, is a more detailed supervised overnight test that measures a wider set of physiological channels.
In Singapore, a doctor may choose a home sleep test when suspected OSA is straightforward. A doctor may choose polysomnography when the picture is more complex or when full sleep architecture and additional signals are needed.
| Feature | Home sleep test | Lab sleep study |
|---|---|---|
| Where it is done | Usually at home | Sleep lab or hospital |
| Main purpose | Breathing-focused assessment | Detailed overnight sleep assessment |
| Typical signals | Airflow, breathing effort, pulse rate, oxygen saturation, sometimes body position | Airflow, breathing effort, oxygen saturation, ECG, brain waves, eye movements, muscle activity, sleep stages |
| Common formats | Type 3 and sometimes Type 2 | Full polysomnography |
| Best suited for | Suspected uncomplicated OSA | More complex symptoms or uncertain diagnosis |
| Main limitation | Fewer channels, less detail on sleep stages | More involved and less convenient |
Comooz supports home sleep test options in Singapore. Based on current service information, Type 3 home sleep tests are available on demand, while Type 2 tests are arranged manually with a trained specialist.
Type 2 vs Type 3 home sleep test
A Type 3 home sleep test is a breathing-focused test that uses fewer channels and is commonly used when OSA is suspected. A Type 2 home sleep test uses more channels and is arranged more selectively when more detail is needed outside a lab setting.
The practical difference is not just the number of sensors. A Type 2 study can provide a more detailed overnight picture, while a Type 3 study is often chosen for convenience and targeted screening of sleep-disordered breathing.
Which option is usually right for you?
A home sleep test is usually for people with a strong suspicion of uncomplicated obstructive sleep apnoea. A lab polysomnography is usually for people whose symptoms, history, or prior results make a simpler study less definitive.
| Situation | Often the more suitable first step | Why |
|---|---|---|
| Loud snoring, witnessed apnoeas, daytime sleepiness, otherwise straightforward case | Type 3 home sleep test | Targets breathing events efficiently |
| Need more detail outside a lab | Type 2 home sleep test | Adds channels compared with Type 3 |
| Complex symptoms or uncertain diagnosis | Polysomnography | Captures sleep stages and broader physiology |
| Concern about non-obstructive patterns | Polysomnography or specialist review | Allows fuller assessment beyond simple OSA screening |
How a sleep test works step by step
A sleep test usually follows the same broad pathway: suitability review, equipment setup, overnight recording, data return, and medical interpretation. The exact details differ between home testing and lab polysomnography.
1. Clinical review and suitability check
A doctor or sleep service reviews symptoms, sleep habits, medical history, and risk factors. This is where they decide whether a home sleep test is likely to answer the clinical question or whether a more detailed test is needed.
2. Equipment setup
For a home sleep test, sensors are attached before bedtime. These commonly include a nasal airflow sensor, breathing effort belts, and a finger probe for oxygen saturation.
A Type 3 setup is the usual breathing-focused format. A Type 2 setup involves more channels and is arranged more selectively.
3. Overnight recording
You sleep with the device in place while it records overnight data. In a sleep lab, staff supervise the study; at home, the data is recorded for later download and review.
4. Data return and quality check
After the sleep test, the device or data card is returned to the provider. The recording is checked for signal quality before formal interpretation.
5. Doctor review and next-step planning
A doctor reviews the report together with your symptoms and medical history. This is important because a sleep test informs diagnosis and treatment decisions, but the device itself does not diagnose in isolation.
How doctors interpret sleep test results
Doctors interpret a sleep test by looking at event frequency, oxygen impact, signal quality, and the patient’s overall clinical picture. The key question is not just whether events occurred, but how often, how severe, and how well the results match the symptoms.
Common report elements include:
-
AHI or apnoea-hypopnoea index
-
Types of breathing events
-
Degree and pattern of oxygen desaturation
-
Positional effects
-
Snoring-related channels where available
-
Sleep stages, if the test was a polysomnography
In lab studies, doctors can also see whether events cluster during REM sleep and whether repeated arousals fragment sleep. In home studies, interpretation is more focused on breathing metrics and less on full sleep architecture.
If the result is unclear, the doctor may recommend repeat testing, a different test format, or review by a sleep physician.
Sleep apnoea severity: AHI ranges and what they mean
AHI is the number of apnoeas and hypopnoeas per hour of sleep or per hour of recording, depending on the test type. AHI is one of the main metrics used to classify sleep apnoea severity.
| AHI range | Severity |
|---|---|
| Less than 5 | Usually not classified as sleep apnoea on AHI alone |
| 5 to 14.9 | Mild |
| 15 to 29.9 | Moderate |
| 30 or more | Severe |
AHI is useful, but it is not the whole picture. Doctors also consider symptoms, oxygen desaturation, event type, cardiovascular context, and whether the results clearly fit obstructive sleep apnoea or need further work-up.
How much a sleep test may cost in Singapore
Sleep test pricing in Singapore varies by test type, provider, and whether consultation, interpretation, and follow-up are bundled. In general, home testing is usually less expensive than full in-lab polysomnography.
This article does not state a fixed public price for every sleep test format because the final cost depends on what is included. When comparing providers, ask whether the fee includes setup, report interpretation, doctor review, repeat testing, and follow-up.
A practical way to compare quotes is to check five items: the test format, who interprets the report, whether follow-up is included, whether repeat setup is chargeable, and how fast results are usually reviewed. Those details often matter more than the headline number alone.
If treatment is recommended after a sleep test, Comooz publishes current CPAP bundle prices as follows:
| Therapy option | Published price | What is included |
|---|---|---|
| ResMed AirSense 10 AutoSet Bundle | $1,868 nett | Main unit, power supply, built-in humidification, tubing, filter, carrying case, fitted mask |
| ResMed AirSense 11 AutoSet Bundle | $2,068 nett | Main unit, power supply, built-in humidification, tubing, filter, carrying case, fitted mask |
You can review current CPAP machine options and bundle pricing if your sleep test leads to treatment discussion.
What happens after a sleep test
After a sleep test, the next step is usually a doctor review. The doctor explains what the report shows, whether it supports sleep apnoea or another breathing-related problem, and what management options may be appropriate.
If OSA is suspected or confirmed, options may include weight management, positional strategies, ENT review, oral appliance therapy, or CPAP. Some patients may also need titration, which means determining an effective treatment pressure.
Modern CPAP treatment often uses auto-adjusting devices such as ResMed AutoSet machines. These can include built-in humidification, which may improve comfort for people who develop dryness or congestion.
Mask choice matters too. Nasal pillow vs full face decisions often depend on comfort, mouth leak, congestion, and whether you mostly breathe through your nose or mouth during sleep. In more pressure-sensitive cases, a doctor may consider bilevel therapy, where inspiratory pressure and EPAP are managed differently.
A sleep test is therefore the start of the pathway, not the end of it.
If CPAP is recommended: machine and mask basics
If a sleep test leads to CPAP treatment, the two main decisions are machine type and mask type. For many patients, comfort and fit matter as much as raw machine features.
The ResMed AirSense 11 AutoSet has a full-colour touchscreen, Climate Control with integrated humidifier, over-the-air updates, and Care Check-in. The ResMed AirSense 10 AutoSet has a monochrome display with dial, integrated HumidAir chamber, built-in cellular connectivity for the myAir app, and a proven robust workhorse design.
| Option | Best fit for | Notes |
|---|---|---|
| Nasal pillows mask | People who want minimal facial contact | Often preferred by nasal breathers |
| Nasal mask or nasal cradle | People who want a balance of stability and openness | Useful when pillows feel too direct |
| Full face mask | Mouth breathers or people with frequent mouth leak | Covers nose and mouth |
| AutoSet CPAP | Most people starting CPAP | Adjusts pressure automatically |
| Bilevel therapy | Selected cases based on doctor advice | Different inspiratory pressure and EPAP |
Nasal pillow vs full face: a quick guide
A nasal pillows or nasal mask setup is usually better for people who mainly breathe through the nose. A full face mask is often considered when mouth leak, mouth breathing, or nasal blockage make nasal-only masks less practical.
| Mask style | Usually suits | Trade-off |
|---|---|---|
| Nasal pillows | Minimal-contact users, clear nasal breathing | May feel too direct for some |
| Nasal cradle / nasal mask | People wanting a middle ground | Still relies mainly on nasal breathing |
| Full face | Mouth breathers or frequent mouth leak | More facial coverage |

Frequently asked questions
What is the difference between a sleep test and a sleep study?
The terms are often used interchangeably, but “sleep test” is the broader term. It can refer to either a home sleep test or an in-lab polysomnography. In practice, the main difference is the format your doctor recommends based on symptoms, medical history, and how much overnight detail is needed.
Can I do a sleep test at home in Singapore?
Yes, some people in Singapore are suitable for a home sleep test, especially when obstructive sleep apnoea is strongly suspected and the clinical picture is straightforward. Home testing is more convenient, but it records fewer channels than lab polysomnography, so a doctor should decide whether it is appropriate for you.
How much does a sleep test cost in Singapore?
The cost of a sleep test in Singapore varies by provider, test format, and whether setup, doctor interpretation, and follow-up are included. Home sleep tests are usually less expensive than in-lab studies. Always confirm the full package price and ask whether repeat setup, review appointments, or extra reports are charged separately.
Is a sleep test painful or unsafe?
A sleep test is generally non-invasive and considered safe. The sensors are attached to the skin or worn on the body to record airflow, oxygen levels, heart rate, and breathing effort. Most people find the main drawback is inconvenience or sleeping less naturally with the equipment in place.
What does AHI mean on a sleep test report?
AHI stands for apnoea-hypopnoea index. It estimates how many breathing interruptions occur per hour of sleep or recording, depending on the test method. Doctors use AHI to grade severity, but they do not rely on it alone; symptoms, oxygen desaturation, and the wider clinical picture also matter.
What happens if my sleep test suggests sleep apnoea?
If a sleep test suggests sleep apnoea, the next step is usually a review with a doctor or sleep specialist. They will discuss severity, symptoms, and suitable options such as lifestyle measures, positional therapy, oral appliance treatment, ENT review, CPAP, or further titration depending on the overall clinical picture.
