A short self-assessment can quickly tell you whether your sleep apnea risk is low, intermediate, or high, and it is one of the fastest ways to decide if an at-home sleep test makes sense for you.
You may be here because your partner finally said something about the snoring. Maybe you wake up tired no matter how many hours you logged. Maybe you have read enough about sleep apnea to wonder if you are quietly living with it, but the idea of an in-lab study has kept you putting it off.
You are not alone if you have been on the fence for years. At iSLEEP, our entire mission is to make sleep care radically simple, human, and accessible, starting with a 2-minute self-check you can take right now. The questions below are based on STOP-BANG, the same risk-screening tool sleep clinicians use every day. A higher score suggests you may benefit from testing. It does not diagnose sleep apnea.
The Numbers You Need to Know
-
An estimated 80% of obstructive sleep apnea cases in the U.S. are undiagnosed
-
STOP-BANG scores of 5 or higher have a sensitivity of about 93% for detecting moderate-to-severe OSA
-
Roughly 70% of patients flagged as high risk by STOP-BANG go on to test positive for clinically significant OSA
Why a Self-Assessment Is a Smart First Filter (Not a Diagnosis)
A sleep apnea self test quiz is not a verdict. It is a filter. The job of a screener is to help you decide whether the next step, a real diagnostic test, is worth taking now or whether you can probably watch and wait.
The most widely used adult screener in clinical practice is STOP-BANG, an eight-question tool developed for surgical pre-operative screening that has since become a default risk-stratifier in primary care and sleep clinics. As noted by the American Academy of Sleep Medicine:
"Among the nearly 30 million U.S. adults who have OSA, about 80% are undiagnosed." - AASM, 2023
That undiagnosed gap is exactly what a screener is meant to close. STOP-BANG performs especially well at the higher end of the scale. Research summarized by the National Library of Medicine shows it has a sensitivity of around 93% for moderate-to-severe OSA at a threshold of 5 or higher. In other words, if you score high, the odds you have meaningful sleep apnea are very real.
The Epworth Sleepiness Scale is a separate screener that focuses on daytime sleepiness, how likely you are to doze off in everyday situations like reading, watching TV, or sitting at a red light. It complements STOP-BANG well, but it does not replace it. STOP-BANG captures your physical risk profile; Epworth captures the symptom burden you are living with right now.
Either way, a screener cannot measure your apnea-hypopnea index (AHI) or your overnight oxygen levels. Only a sleep study can do that. If you score high here, the right next step is testing and with our at-home sleep test, you can have a board-certified physician's report in your hands in about 72 hours, for a flat $189.
The 8-Question Self-Assessment (STOP-BANG-Style)
Answer each question honestly with a yes or no. Give yourself one point for every "yes." Take your time. Your partner may be a useful tiebreaker for the first three.
-
Snoring: Do you snore loudly, loudly enough to be heard through a closed door, or loudly enough that your bed partner has elbowed you about it?
-
Tired: Do you often feel tired, fatigued, or sleepy during the daytime, even after a full night in bed?
-
Observed: Has anyone ever observed you stop breathing, gasp, or choke during your sleep?
-
Pressure: Do you have, or are you being treated for, high blood pressure?
-
BMI: Is your body mass index greater than 35 kg/m²?
-
Age: Are you older than 50 years?
-
Neck: Is your neck circumference greater than 16 inches (40 cm) for women, or greater than 17 inches (43 cm) for men?
-
Gender: Are you male?
Add up your "yes" answers. Your total is somewhere between 0 and 8. That number is your STOP-BANG score, and it lines up with a published risk band, keep reading.
How to Read Your Score
The validated STOP-BANG cut points break risk into three bands. Use the table below to find yours, and then read the recommended next step.
|
Score |
Risk Level |
Recommended Next Step |
|---|---|---|
|
0 – 2 |
Low risk of OSA |
If you are sleeping well and feel rested, no immediate testing is required. Re-screen yearly or if symptoms change. If your partner reports loud snoring or you feel persistently tired, still consider talking to a clinician. |
|
3 – 4 |
Intermediate risk of OSA |
Testing is reasonable, especially if you have any of the "STOP" symptoms (snoring, tiredness, observed apneas, or hypertension). An at-home sleep test is a low-friction way to confirm. |
|
5 – 8 |
High risk of OSA |
Strongly consider testing soon. STOP-BANG ≥5 has approximately 93% sensitivity for moderate-to-severe OSA. Booking the iSLEEP at-home test is a sensible next step. |
A higher score suggests you may benefit from testing. It does not diagnose sleep apnea on its own. The only way to know your AHI and oxygen desaturation pattern is a validated sleep study reviewed by a board-certified physician.
What the Quiz Can't Capture
STOP-BANG is excellent at flagging the typical risk profile, but it can miss real cases. You are not alone if your symptoms feel obvious to you and yet your score lands lower than you expected.
A few patterns the quiz tends to underweight:
-
Women, especially pre-menopausal: Women often present with insomnia, fatigue, mood changes, or morning headaches rather than loud snoring, and they typically score lower on STOP-BANG even when they have meaningful OSA. Symptoms in women are often dismissed for years.
-
Thin and physically fit adults: If your BMI is normal and your neck is slender, you may score 0 on three of the eight items even with significant airway-anatomy-driven apnea.
-
Younger adults: Anyone under 50 starts a point behind on STOP-BANG, but OSA absolutely occurs in people in their 20s, 30s, and 40s, particularly with retrognathia (a recessed jaw), a narrow palate, or chronic nasal obstruction.
-
Atypical symptoms: Nocturia (waking up to urinate more than twice a night), bruxism (teeth grinding), unrefreshing sleep, brain fog, and worsening reflux are all linked to OSA but are not in STOP-BANG.
-
Central sleep apnea: STOP-BANG was built for obstructive apnea. CSA, driven by heart failure, opioids, or stroke, has a different profile and is not what this screener is calibrated for.
If your symptoms do not match the stereotype but they feel real, they probably are. Our deep dive on the symptoms of sleep apnea and how to spot them early covers the less obvious presentations in detail, and our piece on why snoring isn't normal explains why "everyone snores" is a quiet problem.
What to Do If You Scored High
A high STOP-BANG score is a strong nudge toward testing, not toward panic. The path forward is straightforward, and you have more options than you may realize.
For most uncomplicated adults, an at-home sleep apnea test (HSAT) is a validated, accurate, and far less disruptive way to get answers than a clinical lab study. For most uncomplicated adults, an at-home sleep apnea test (HSAT) is a validated, accurate, and far less disruptive way to get answers than a clinical lab study. The American Academy of Sleep Medicine recognizes home sleep apnea testing as an appropriate diagnostic option for uncomplicated adults with signs of an increased risk of moderate-to-severe OSA, exactly the group a high STOP-BANG score flags.
iSLEEP's at-home sleep test uses the WatchPAT One device, which has shown approximately 98% correlation with in-lab polysomnography. The flat $189 price covers the device and a board-certified sleep physician's review of your results, typically within 72 hours. You sleep in your own bed. There is no insurance gauntlet and no overnight stay in a clinic.

When to Skip the Quiz and See a Sleep Specialist Directly
For a small group of people, a self-assessment is not the right starting point, a sleep specialist is. Consider going straight to a clinician, and not relying on a screener, if any of the following apply.
-
You have witnessed pauses in breathing followed by gasping or choking
-
You have fallen asleep while driving, or had a near-miss because of drowsiness
-
You have been diagnosed with heart failure, atrial fibrillation, refractory hypertension, or have had a stroke
-
You are using opioids regularly or have been told you have unusual breathing patterns at night
-
You have severe excessive daytime sleepiness that is interfering with work, school, or relationships
-
You are pregnant and have new-onset loud snoring or witnessed apneas
The Cleveland Clinic notes that excessive daytime sleepiness is one of the most common reasons people are referred for sleep evaluation, and it is also one of the most under-reported. If your sleepiness has crossed from inconvenient to dangerous, do not wait for a quiz score to validate that.
How the Epworth Sleepiness Scale Fits In
STOP-BANG asks "what is your risk profile?" The Epworth Sleepiness Scale asks a different question: "how sleepy are you, really?"
The Epworth Sleepiness Scale is a short self-rated questionnaire that asks how likely you are to doze off in eight everyday situations, including sitting and reading, watching TV, sitting in a public place, riding as a passenger for an hour, lying down to rest in the afternoon, sitting and talking with someone, sitting quietly after lunch without alcohol, and waiting in a stopped car in traffic. Each item is scored 0 to 3, for a total range of 0 to 24. Scores above 10 generally indicate excessive daytime sleepiness.
Used together, STOP-BANG and Epworth give you a fuller picture: one tells you whether your physiology is consistent with OSA, the other tells you whether your daily life is being impacted by sleepiness. If both are elevated, the case for testing is strong. If your STOP-BANG is intermediate but your Epworth is high, that combination still warrants a sleep evaluation, even if the numbers individually feel borderline.
What to Expect From the iSLEEP At-Home Sleep Test
If you decide to move forward, the experience is intentionally low-friction. Here is what actually happens.
-
You order online at a flat $189. No insurance is required, and the price is the entire price.
-
The kit arrives with a single-use, FDA-cleared WatchPAT One device. You wear it for one night, in your own bed, on a normal night of sleep.
-
The device records peripheral arterial tone, oxygen saturation, heart rate, body position, and snoring. You return the data through the app. There is nothing to mail back, because the device is disposable.
-
A board-certified sleep physician reviews your data and writes a clinical report. You typically have your results within 72 hours.
-
You get a clear next step. If you have OSA, our team helps you move into treatment. If you do not, you have peace of mind and a documented baseline.
The home test is not the right tool for every patient, including central sleep apnea, severe cardiopulmonary disease, and some pediatric cases still call for in-lab polysomnography. Your physician's review will flag any case where lab testing is the more appropriate path.
FAQ
How accurate is a sleep apnea self test quiz?
STOP-BANG, the basis of this quiz, has a sensitivity of about 93% for moderate-to-severe OSA at a threshold of 5 or higher, meaning it catches the great majority of people who actually have meaningful apnea. Its specificity is lower, so some people with high scores do not have OSA. That is why the result is a flag for testing, not a diagnosis. A validated home sleep apnea test or in-lab polysomnography is required to confirm OSA and measure your AHI.
What's the difference between STOP-BANG and the Epworth Sleepiness Scale?
STOP-BANG asks about risk factors and core symptoms, such as snoring, daytime tiredness, observed apneas, blood pressure, BMI, age, neck circumference, and gender. The Epworth Sleepiness Scale measures how likely you are to doze off in everyday situations and produces a 0 to 24 sleepiness score. They answer different questions and are most useful when used together.
Can I have sleep apnea and still score low on the quiz?
Yes. Women, thin or physically fit adults, and people younger than 50 routinely score in the low or intermediate range and still test positive for OSA. STOP-BANG was calibrated on the typical adult risk profile and tends to underweight atypical presentations. If you have meaningful symptoms, gasping awakenings, unrefreshing sleep, morning headaches, brain fog, or witnessed apneas, testing is reasonable regardless of your numerical score.
Should I do an at-home test or an in-lab study first?
For most uncomplicated adults with a high pre-test probability of OSA, an at-home sleep apnea test is appropriate and is recognized as a valid diagnostic option by major U.S. clinical bodies. In-lab polysomnography is generally reserved for cases involving suspected central sleep apnea, significant cardiopulmonary disease, complex comorbidities, or when an HSAT result is inconclusive. A board-certified physician reviews your situation and recommends the right path.
How fast can I get results from the iSLEEP at-home test?
You typically receive a board-certified physician's report within about 72 hours after you complete the night of testing. The flat price is $189, and there is no insurance step in the way. If your results are positive for OSA, the iSLEEP team helps you move into the appropriate next step, whether that is CPAP, an oral appliance, or further evaluation.
Better Sleep Doesn't Just Happen — Here's How to Move Forward
You came here for a clear-eyed read on whether testing is worth your time. If your STOP-BANG score landed in the intermediate or high band, the honest answer is yes and you do not have to start with a clinical sleep lab to find out where you stand. With our at-home sleep test, you can confirm in your own bed, in about 72 hours, at $189 flat, with a board-certified physician reviewing every result.
