Quick answer
In Singapore, sleep apnoea diagnosis usually starts with symptoms, risk assessment and a sleep study such as a Type 3 home sleep test, Type 2 home study or in-lab polysomnography. Doctors confirm obstructive sleep apnoea using AHI, oxygen desaturation, event patterns and clinical history, then recommend next steps such as CPAP, titration or specialist review.

What sleep apnoea diagnosis in Singapore involves
Sleep apnoea diagnosis in Singapore is a medical process, not a single gadget result. A doctor or sleep physician reviews symptoms, medical history, examination findings and sleep study data before confirming obstructive sleep apnoea, central sleep apnoea or another sleep-related breathing disorder.
The aim is to determine whether breathing repeatedly narrows or stops during sleep, how often it happens, and how much it affects oxygen levels and sleep quality. Common markers include AHI, oxygen desaturation, snoring patterns, breathing effort and whether events appear obstructive or central.
A diagnosis may involve a GP, ENT doctor or sleep physician depending on the case. People with suspected OSA often start with a consultation, then move to a home sleep test or polysomnography.
Who this guide is for and when to seek assessment
This guide is for adults in Singapore who suspect sleep apnoea, have been told they snore heavily, or have already been advised to do a sleep study. It is also useful for partners or family members who notice choking, gasping or witnessed pauses in breathing.
This guide is not for self-diagnosis or emergency assessment. If sleepiness affects driving or work safety, or if you have major heart, lung or neurological conditions, speak to a doctor or sleep specialist promptly.
Common reasons people seek sleep apnoea diagnosis in Singapore include:
-
loud habitual snoring
-
witnessed breathing pauses
-
choking or gasping during sleep
-
unrefreshing sleep
-
morning headaches
-
dry mouth on waking
-
daytime sleepiness
-
poor concentration or irritability
Doctors also look at risk factors such as excess weight, larger neck size, hypertension, nasal blockage, increasing age, male sex and family history. Screening tools such as the Epworth Sleepiness Scale can support assessment, but they do not diagnose sleep apnoea on their own.
How sleep apnoea is diagnosed: consultation, screening and sleep testing
Sleep apnoea diagnosis in Singapore usually follows a stepwise path: consultation, screening, sleep testing, report interpretation and treatment planning. This helps separate simple snoring from clinically important sleep-disordered breathing.
At consultation, the doctor usually asks about snoring, witnessed apnoea, choking, sleep quality, daytime fatigue, shift work, alcohol use, medical conditions and medication history. The examination may include the nose, throat, jaw, neck and blood pressure, plus a review of weight-related risk.
A sleep study is then selected based on how likely OSA is and whether the case appears straightforward or complex. In adults with suspected uncomplicated obstructive sleep apnoea, a home sleep test is often the most convenient first step.
A home sleep test is a portable breathing-focused study done outside the sleep lab. Comooz offers home sleep test in Singapore access, including on-demand Type 3 testing and manual arrangement for Type 2 testing with a trained specialist.
Polysomnography is a fuller in-lab sleep study. It may be preferred when symptoms are unclear, another sleep disorder is suspected, or a home study is inconclusive.
Home sleep test vs in-lab polysomnography in Singapore
A home sleep test and in-lab polysomnography both assess sleep-disordered breathing, but they answer different levels of clinical detail. The best test depends on the suspected diagnosis and how much monitoring the doctor needs.
| Feature | Type 3 home sleep test | Type 2 home sleep test | In-lab polysomnography |
|---|---|---|---|
| Where it is done | Usually at home | At home | Sleep lab or hospital |
| Who it suits | Adults with likely uncomplicated OSA | Cases needing more signals than Type 3 | Complex, unclear or non-routine cases |
| What it typically measures | Breathing signals such as airflow, effort and oxygen levels | More channels than Type 3, depending on setup | Broader signals including breathing, brain waves and other physiologic data |
| Convenience | High | Moderate | Lowest |
| Supervision | Self-applied or guided setup | Manual arrangement with trained specialist | Direct lab supervision |
| When doctors may prefer it | Straightforward suspected OSA | When added detail is needed outside the lab | Possible central apnoea, other sleep disorders, or inconclusive home testing |
A Type 3 home sleep test is commonly used because it is practical and focused on breathing-related sleep problems. A Type 2 home sleep test captures more detail and is arranged manually when that extra level is needed.
Polysomnography remains important when doctors suspect central sleep apnoea, parasomnias, limb movement disorders or more complex cardiorespiratory issues.
What your sleep study results mean: AHI, oxygen levels and severity
Sleep study reports translate overnight data into clinically useful numbers. The main number most patients see is AHI, but doctors do not use AHI alone.
AHI stands for apnoea-hypopnoea index. It is the number of apnoeas and hypopnoeas per hour of sleep or monitoring. In adults, common severity bands are:
-
AHI 5 to 14: mild
-
AHI 15 to 29: moderate
-
AHI 30 or more: severe
Doctors also review oxygen desaturation, the length and pattern of events, snoring, body position effects and whether events look obstructive or central. A report may show a lower AHI but still matter clinically if symptoms are strong or oxygen dips are notable.
This is why a doctor or sleep physician should interpret the study. The diagnosis connects the numbers to your symptoms, safety concerns and the most suitable next step.
When doctors may recommend one test over another
Doctors choose the test according to clinical suspicion, not convenience alone. Straightforward suspected obstructive sleep apnoea often starts with home testing, while more complex cases may need polysomnography from the outset.
A home sleep test may suit you if
A home sleep test may be appropriate if you are an adult with loud snoring, witnessed pauses and daytime tiredness, especially when obstructive sleep apnoea is strongly suspected and there are no obvious complicating factors.
Polysomnography may be preferred if
Polysomnography may be preferred if symptoms are atypical, if another sleep disorder is suspected, or if the doctor needs full-channel monitoring. It may also be used when home sleep test data is borderline, technically limited or does not match the clinical picture.
Type 2 testing fits the middle ground
A Type 2 home sleep test sits between simple Type 3 testing and lab polysomnography. At Comooz, Type 2 testing is arranged manually with a trained specialist rather than being offered as a standard on-demand option.
Conditions linked with sleep apnoea and why proper diagnosis matters
Proper diagnosis matters because untreated sleep apnoea can overlap with other health problems and impair daily function. It can also be mistaken for ordinary snoring, stress or poor sleep habits.
People with suspected OSA may also have hypertension, cardiometabolic risk, poor concentration, mood changes or drowsy driving concerns. Diagnosis helps clarify whether sleep-disordered breathing is likely to be a major contributor.
A correct diagnosis supports the right treatment pathway. CPAP, oral appliance therapy, positional strategies, weight management and ENT-led care are not interchangeable, and the right choice depends on severity, anatomy and symptoms.
What happens after a diagnosis in Singapore
After sleep apnoea diagnosis in Singapore, the next step depends on severity, symptoms, anatomy and doctor advice. Moderate to severe OSA often leads to CPAP discussion, while milder cases may involve more targeted alternatives or combination strategies.
CPAP is a standard non-surgical therapy for many adults with obstructive sleep apnoea. Auto-adjusting devices such as ResMed AutoSet machines can vary pressure across the night, and humidification often improves comfort and reduces dryness.
Some patients are started on auto-adjusting treatment, while others may need formal titration. If pressure intolerance or more specific pressure support is required, a sleep physician may consider bilevel therapy, where inspiratory pressure and EPAP are separated.
| Option | Best suited for | Notes |
|---|---|---|
| CPAP or AutoSet therapy | Many patients with moderate to severe OSA | Pressure may be set by auto-adjusting therapy or titration |
| Bilevel therapy | Selected patients who need different inspiratory and expiratory pressures | Uses separate pressure support and EPAP settings; example: ResMed AirCurve 10 VAuto |
| Weight management | Patients with excess weight contributing to airway risk | Usually part of a broader plan |
| Positional therapy | Positional OSA or back-sleep worsening | Best guided by test findings |
| Oral appliance therapy | Selected mild to moderate cases or CPAP-intolerant patients | Usually coordinated with a trained dental provider |
| ENT or nasal evaluation | Structural blockage or chronic congestion | Useful when anatomy affects airflow or mask tolerance |
Sleep apnoea diagnosis and treatment costs in Singapore
Testing costs in Singapore vary by provider, test type and what is included. The safest approach is to ask for a written breakdown before booking.
Home sleep testing is often less expensive and more convenient than in-lab polysomnography, while in-lab testing may cost more because it involves more channels and closer supervision. Comooz does not claim a universal Singapore diagnosis price because medical providers structure fees differently.
What Comooz can state clearly is its current therapy pricing and policies for patients who have already been advised to start CPAP.
| Product or service | Current price or policy | What to know |
|---|---|---|
| ResMed AirSense 10 AutoSet Bundle | $1,868 nett | Includes main unit, power supply, built-in humidification, tubing, filter, carrying case and a fitted mask |
| ResMed AirSense 11 AutoSet Bundle | $2,068 nett | Includes main unit, power supply, built-in humidification, tubing, filter, carrying case and a fitted mask |
| 5-night CPAP trial | Deposit + mask cost + $98 return fee | It is not a free trial |
| CPAP rental | Monthly | 3-month offset rules apply toward purchase |

The ResMed AirSense 10 AutoSet uses a monochrome display with dial, integrated HumidAir chamber, built-in cellular connectivity for the myAir app, and a proven workhorse design.
Mask choice matters as much as machine choice. Nasal pillow masks often suit nose breathers who want a lighter feel, while full face masks may suit people with frequent mouth breathing or mouth leak. Nasal cradle and standard nasal masks sit in the middle for many users.
| Mask type | Often suits | Example discussed here |
|---|---|---|
| Nasal pillows | Users who prefer minimal facial contact | ResMed AirFit P30i or AirFit P10 |
| Nasal cradle or nasal mask | Nose breathers who want a balance of comfort and seal | ResMed AirFit N30i or AirFit N20 |
| Full face | Mouth breathers or users needing nose-and-mouth coverage | ResMed AirFit F20 or AirTouch F20 |
Humidification also affects comfort. Built-in humidification can reduce dryness and make it easier to stay on therapy, especially when airflow feels drying through the nose or mouth.

Frequently asked questions
How do I get tested for sleep apnoea in Singapore?
Testing usually starts with a consultation about symptoms such as loud snoring, witnessed pauses in breathing, poor sleep, morning headaches or daytime sleepiness. A doctor may then recommend a Type 3 home sleep test, a Type 2 home study or in-lab polysomnography. Diagnosis should be confirmed by a qualified doctor or sleep specialist.
Can a home sleep test diagnose sleep apnoea accurately?
A home sleep test can detect obstructive sleep apnoea in many adults with a moderate to high likelihood of uncomplicated OSA. However, it is not ideal for every case, especially if symptoms are unclear or other sleep, heart, lung or neurological issues are suspected. A doctor should decide if it is appropriate and interpret the report.
What is the difference between sleep apnoea and snoring?
Snoring is a sound caused by vibration in the upper airway. Sleep apnoea involves repeated partial or complete airway blockage, or less commonly central pauses in breathing, during sleep. Not everyone who snores has sleep apnoea, but loud habitual snoring with choking, gasping or daytime sleepiness should be assessed medically.
What AHI number means I have sleep apnoea?
AHI measures the number of apnoeas and hypopnoeas per hour of sleep or monitoring. In adults, common thresholds are 5-14 mild, 15-29 moderate and 30 or more severe. Doctors do not rely on AHI alone, because oxygen desaturation, event type, symptoms and medical history also affect diagnosis and treatment decisions.
How much does sleep apnoea testing cost in Singapore?
Costs vary by provider, test type and whether consultation and report review are included. Home sleep testing is often less expensive than in-lab polysomnography, but there is no single universal Singapore price. Patients should ask for a written breakdown covering consultation, setup, reporting and the follow-up review before booking.
What happens if I am diagnosed with sleep apnoea?
The next step depends on severity, symptoms and your medical profile. Treatment may include CPAP, weight management, positional therapy, oral appliance therapy, nasal or ENT review, or other measures. If CPAP is advised, setup may include mask fitting, humidification adjustment and pressure optimisation through auto-adjusting therapy or titration.
What is the difference between Type 2 and Type 3 home sleep tests?
A Type 3 home sleep test is a breathing-focused study that usually measures airflow, respiratory effort and oxygen levels. A Type 2 home sleep test uses more channels and can provide more detail outside the lab. In Singapore, doctors may use Type 3 for straightforward suspected OSA and reserve Type 2 for cases needing extra data.
