STOP-BANG (Snoring, Tiredness, Observed apnea, blood Pressure, BMI, Age, Neck circumference, Gender)

Do I have sleep apnea?

This 8-question STOP-BANG test (about 2 minutes) estimates your risk level for obstructive sleep apnea. It is intended for any adult, particularly in the presence of snoring, daytime fatigue, or factors such as excess weight. The result distinguishes low, intermediate, or high risk, with the high level suggesting a conversation with your doctor.

Please read before you start: this guidance tool does not replace a medical consultation. It does not provide a diagnosis.

  • A low or normal result does not rule out the need to see a doctor if you have another symptom that this specific test does not cover.
  • Depending on your age or the guidelines in your country, a consultation may still be advisable even with a negative result.

I snore loudly — is that serious?

Snoring alone isn't always a sign of sleep apnea: plenty of people snore without it causing them any harm. What should catch your attention is a combination of several signs: loud, regular snoring, breathing pauses noticed by a partner, noticeable daytime fatigue despite what feels like a full night's sleep, or blood pressure that's hard to control. That combination is exactly what the test above tries to identify.

Why am I tired all the time?

Persistent daytime fatigue or sleepiness has many possible causes (lack of sleep, stress, deficiencies, certain medical conditions...). Sleep apnea is one of them, and it's often underestimated, because it's sleep itself that gets fragmented by repeated micro-awakenings, without the person being aware of it in the morning.

What is sleep apnea?

Sleep apnea (more precisely, obstructive sleep apnea syndrome, or OSA) is characterized by repeated breathing pauses during sleep, caused by an excessive relaxation of the throat tissues that temporarily blocks the airway. These pauses fragment sleep without the person necessarily realizing it, which explains the daytime fatigue often associated with it. Left untreated, it can have long-term cardiovascular and metabolic consequences.

Why these specific 8 questions?

This test is based on the STOP-BANG questionnaire, a screening tool that has been used and studied in sleep medicine for over a decade. Its name comes from the eight criteria it assesses: Snoring, Tiredness, Observed apnea, Pressure, BMI (body mass index), Age, Neck circumference, and Gender. Its value doesn't come from the total score alone, but from how certain criteria combine with one another — this tool applies that more refined logic (see the sources at the bottom of the page).

What should I do based on my result?

Low risk: your current answers don't match the profile usually associated with sleep apnea. Stay alert if new symptoms appear.

Intermediate risk: neither reassuring nor alarming. If symptoms bother you day to day, talk to your doctor about it.

High risk: it's advisable to discuss this with your doctor fairly soon, who can assess whether a sleep study would be useful.

How does diagnosis work in France?

The typical care pathway in France starts with a consultation with your primary care doctor, who assesses your symptoms and risk factors. If they suspect sleep apnea, they will usually refer you to a pulmonologist or a sleep clinic. Diagnosis relies on a sleep recording: a home-based respiratory polygraphy (measuring breathing and oxygen levels) or, in some cases, a more complete polysomnography performed in a sleep lab. These tests confirm the diagnosis and assess its severity. If you're based outside France, the exact pathway and terminology may differ, but it typically follows the same overall logic: primary care doctor first, specialist referral if needed, then a sleep study.

Frequently asked questions

Does a low score mean I don't have sleep apnea?

A low score makes moderate to severe sleep apnea less likely, but doesn't rule it out entirely. If your symptoms persist or worsen, it's still worth discussing with your doctor.

Does sleep apnea present differently in women?

Yes, symptoms can be less typical (fatigue, mood changes, insomnia) than the classic picture of snoring and observed breathing pauses, which can delay diagnosis.

Why does neck circumference matter in the calculation?

A larger neck circumference is associated with more soft tissue around the upper airway, which makes it more likely to become obstructed during sleep.

Why Hygietest?

Hygietest is a health hub dedicated to primary care, centered on prevention. The idea is simple: bring together, in one place, several screening tools accessible to everyone, to help each person better understand their health even before seeing a doctor.

Multiple tools, focused on prevention

The site is gradually offering several screening tools, covering prevention in general and cardiovascular health in particular — two areas where catching an early signal often changes what comes next: sleep, blood pressure, weight, chronic fatigue. Each tool is designed for one-off use, with no account and no tracking over time.

Simple tools, built on serious foundations

Each questionnaire is based on studies from the medical literature — both established and recent — already used in clinical practice. Hygietest's job is to make them accessible: the same method, the same rigor, but language designed to be understood without any medical training.

Free, with no personal data collection

Hygietest is entirely free. No identity is requested, no payment details, no account creation. Calculations happen directly in your browser: nothing is transmitted, nothing is stored.

What Hygietest is not

Hygietest does not replace, and is not intended to replace, a medical consultation — whether as part of a screening approach or when symptoms appear. A reassuring result never rules out the possibility of seeing a doctor: if doubt remains, or if a symptom not covered by the test worries you, talking to a healthcare professional remains the right approach.

Screening is not diagnosing

This is an important distinction, often misunderstood: a screening tool doesn't serve the same purpose as a diagnostic test. Its main value lies in its ability to flag a risk — its sensitivity — rather than to confirm a diagnosis with certainty, which is the role of specificity and further testing carried out by a doctor. A positive result on a screening test is therefore not a diagnosis: it's an indication that it's worth discussing with a healthcare professional, who will decide whether further tests are needed.

Our goal

Hygietest is purely a tool for making screening more accessible, designed as a complement — never a substitute — to the usual care pathway. The ultimate goal is simple: promote screening to support prevention, by increasing the likelihood that people take the step of seeing a doctor when it's useful to do so.

Frequently asked questions
Is Hygietest free?

Yes. Every test is free, with no sign-up required.

Who is behind Hygietest?

The site is offered and reviewed by Dr. BARTHELEMY Pierre L., a general practitioner. The tests weren't invented for the site: they are scores published in medical journals and recommended by health authorities.

Are the tests reliable?

Each tool reuses the questions, formulas, and thresholds from the original publication. Sources are cited on every page. Like any screening test, they estimate a risk: they don't confirm or rule out a disease.

Can a test replace a medical consultation?

No. A low result doesn't rule out seeing a doctor if a symptom worries you, and a high result is a reason to discuss it with your doctor. In an emergency, call your local emergency number.

What happens to my answers?

Nothing: calculations happen in your browser. No answer is transmitted to or stored by Hygietest. The site measures its audience anonymously and in aggregate (page views, country, device type), without cookies, via Vercel; your test answers are never included.

Which tests are offered?

Fourteen tests: cardiovascular risk (SCORE2), cardiovascular risk with diabetes (SCORE2-Diabetes), high blood pressure (home blood pressure monitoring), diabetes risk (FINDRISC), overweight and obesity (BMI), fatty liver disease (FLI), liver fibrosis (FIB-4), sleep apnea (STOP-BANG), sleepiness (Epworth Sleepiness Scale), nicotine dependence (Fagerström test), alcohol consumption (AUDIT-C), physical activity (IPAQ/GPAQ), burnout (CBI), and depression (PHQ-9).

Which test should I start with?

If you don't have a specific question in mind, start with cardiovascular risk and blood pressure: the two most useful markers in prevention.
