L'asma è una condizione a lungo termine che colpisce circa 5,4 milioni di persone nel Regno Unito. Sebbene i farmaci e gli inalatori siano efficaci nel controllare i sintomi, molte persone non sono sicure se il loro asma sia davvero sotto controllo. Il Test di Controllo dell'Asma (ACT) è un metodo rapido e basato su evidenze per verificare quanto bene la tua asma sia gestita nella vita quotidiana.
A colpo d'occhio
The Asthma Control Test (ACT) is a questionnaire for people aged 12 and over.
It asks about your asthma symptoms, activity, and reliever use over the past four weeks.
Your score indicates if your asthma is well controlled, partly controlled, or poorly controlled.
A score of 20-25 suggests well-controlled asthma.
Scores below 20 mean your asthma may not be fully controlled.
Contact your doctor or asthma nurse if your score is 19 or lower.
Seek urgent medical help if your reliever inhaler is not helping, or breathing is very difficult.
What is the Asthma Control Test?
The Asthma Control Test (ACT) is a simple questionnaire that asks about your symptoms, activity levels, and use of reliever inhalers over the last four weeks.
It was developed by asthma specialists and is widely used in both clinical practice and research. The test is validated, meaning it has been shown to be reliable in measuring asthma control, and is recommended by healthcare professionals.
Take the test
Answer five quick questions to get your score.
Your score will give you an idea of whether your asthma is well controlled, partly controlled, or poorly controlled.
Understanding your results
Score 20–25 – Your asthma appears well controlled. Keep taking your medicine as prescribed and continue regular reviews with your doctor or asthma nurse.
Score 16–19 – Your asthma may not be fully controlled. You may be experiencing more symptoms than you should. It’s a good idea to book a review with your doctor or asthma nurse.
Score 5–15 – Your asthma is poorly controlled. You should make an appointment with your doctor or asthma nurse as soon as possible to review your treatment.
Remember: this tool is designed for people aged 12 years and over. There is a separate Childhood Asthma Control Test (C-ACT) for younger children.
Why asthma control matters
Even if your asthma seems “okay,” poor control can increase your risk of asthma attacks, hospital visits, or needing stronger medicine in the future. Symptoms such as coughing at night, wheezing during exercise, or needing your reliever inhaler more than twice a week are all signs that your asthma may not be under control.
Well-controlled asthma means:
Fewer or no day-to-day symptoms.
Sleeping through the night without coughing or wheezing.
Rare use of reliever inhalers.
Being able to enjoy exercise and activities without limitation.
What to do if your score is low
If your ACT score suggests your asthma is not well controlled, don’t ignore it. Book an asthma review with your doctor or asthma nurse. Bring your test result with you - it can help guide the discussion.
In the meantime:
Make sure you are using your inhaler with the correct technique.
Keep taking your preventer inhaler as prescribed, even if you feel well.
Carry your reliever inhaler with you at all times.
Follow your personalised asthma action plan, if you have one.
If you are having frequent symptoms, waking at night, or finding it hard to breathe, seek medical advice promptly.
When to seek urgent help
Call 999 or go to A&E if:
Your reliever inhaler isn’t helping.
You are finding it difficult to speak, eat, or sleep because of your breathing.
Your symptoms are suddenly getting worse.
Asthma attacks can be life-threatening - always act quickly.
Avvertenza
The Asthma Control Test (ACT) is not a diagnostic tool. It does not replace advice from your doctor, asthma nurse, or pharmacist. If you are concerned about your asthma symptoms or your test score is low, seek medical help.
