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.
Answer all 5 questions to see your result (0 of 5 done).
Based on the Asthma Control Test (Nathan et al., J Allergy Clin Immunol 2004), validated for people aged 12 and over. It measures symptom control over the last 4 weeks and does not diagnose asthma or replace your asthma action plan. Nothing you enter is stored, sent or logged.
