Is your asthma under control?

The Asthma Control Test used by GPs and asthma nurses — 5 questions about the last 4 weeks, about 1 minute. For people aged 12 and over with diagnosed asthma. Nothing you enter leaves your device.

Having an asthma attack right now?

  • Your reliever inhaler isn't helping, or you need it more than every 4 hours
  • You're too breathless to speak, eat or sleep
  • Your lips or fingers look blue or grey, or you feel drowsy or confused

If any of these apply, call 112 or 999 now — don't complete this test.

1. In the past 4 weeks, how much of the time did your asthma keep you from getting as much done at work, school or at home?
2. During the past 4 weeks, how often have you had shortness of breath?
3. During the past 4 weeks, how often did your asthma symptoms (wheezing, coughing, shortness of breath, chest tightness or pain) wake you up at night or earlier than usual in the morning?
4. During the past 4 weeks, how often have you used your reliever inhaler or nebuliser (such as salbutamol)?
5. How would you rate your asthma control during the past 4 weeks?
