Free Sleep Apnea Screening Tool - Online Test

There are many sleep apnea screening tools.

Currently, the one most supported by research is the STOP-Bang questionnaire (1, 2).

It’s quite simple, and I’ve made a free online version of the test below to make it even easier. If a new sleep apnea test becomes more popular instead in the future, I will update this page to always contain the most current tool available.

Answer the 8 questions below, and your results will be calculated underneath them in the blue box (you will need JavaScript enabled, so you may have to disable any adblockers).

There is also an additional explanation on why you got the result that you did at the very bottom. 


1. Do you snore loudly (loud enough to be heard through closed doors)?
yes
no
2. Do you often feel tired, fatigued, or sleepy during daytime?
yes
no
3. Has anyone observed you stop breathing during your sleep?
yes
no
4. Do you have or are you being treated for high blood pressure?
yes
no
5. Is your BMI more than 35? (I'm not sure what my BMI is.)
yes
no
6. Are you over 50 years old?
yes
no
7. Is your neck circumference over 40 cm?
yes
no
8. Are you male?

no

Results

Based on your results, you have a low risk of having sleep apnea.

Sleep Apnea Screening Tool Explanation

The scoring for the STOP-Bang test is pretty straight forward. Any answer of “yes” to a question will add to your risk.

There are 3 possible risk levels based on your responses:

  • Low - If you answered “yes” to 0-2 questions, you have a low chance of having sleep apnea. 
  • Intermediate - If you answered “yes” to 3-4 questions, you likely have an intermediate risk of having sleep apnea.
  • High - There are multiple different ways of having a high risk of sleep apnea:
    • Answer “yes” to 5 or more questions
    • Answer “yes” to 2 of the first 4 questions, and also be male
    • Answer “yes” to 2 of the first 4 questions, and also have a BMI over 35
    • Answer “yes” to 2 of the first 4 questions, and also have a neck circumference over 40 cm

As you can see, answering “yes” to certain sets of 3 questions can put you in either the intermediate or high risk categories.

Note that some questions like BMI and age can change, so your risk of developing sleep apnea can increase or decrease over time.

If you do have an intermediate or high risk of having sleep apnea, and you’re having significant sleep issues, it’s time to see a doctor and find out for sure.
