Asthma Control Test (ACT)

Answer five quick questions about the last 4 weeks. Your score (5–25) estimates how well your asthma has been controlled. This tool is educational and not a medical diagnosis.

1) In the past 4 weeks, how often did asthma limit your usual activities (work, school, home)?
2) In the past 4 weeks, how often did you have shortness of breath?
3) In the past 4 weeks, how often did asthma wake you at night or earlier than usual?
4) In the past 4 weeks, how often did you use a quick-relief (rescue) inhaler or nebulizer?
5) Overall, how well controlled has your asthma been during the past 4 weeks?

About the Asthma Control Test

The ACT is a brief questionnaire validated to help estimate asthma control in people aged 12 and above. Clinicians use it to track symptom burden and guide conversations about therapy and triggers.

How your score is used

A higher total (closer to 25) suggests better control. Scores below 20 often indicate suboptimal control and warrant a discussion about triggers, adherence, inhaler technique, and step-up therapy per guideline-based care.

When to seek care urgently

  • Trouble speaking in full sentences, lips/fingertips turning blue, severe breathlessness
  • No relief after rescue inhaler
  • Peak flow <50% personal best

Why it matters: Studies consistently show that an ACT score below 20 indicates not well-controlled asthma, often requiring adjustments in treatment. With our tool, you get immediate insight — empowering you to manage symptoms proactively, with scientific backing and clinical accuracy.

What Is the Asthma Control Test (ACT)?

The Asthma Control Test (ACT) is a simple, validated, patient-reported outcome questionnaire consisting of five key questions. Each question is scored on a 1 to 5 scale:

  1. How often did asthma limit your activities?
  2. How often did you experience shortness of breath?
  3. How often were you woken by asthma symptoms?
  4. How often did you use a rescue inhaler?
  5. Overall, how well controlled was your asthma?

Scores are summed for a total between 5 and 25:

  • 20–25: well-controlled asthma
  • 16–19: not well-controlled
  • 5–15: very poorly controlled

Developed by QualityMetric and endorsed by professional bodies like the American Thoracic Society, the ACT is widely used in clinical and research settings as a reliable measure of asthma control over the past 4 weeks. [Read more at American Thoracic Society]((insert external link)).

Why Track Your ACT Score — Medical Insights & Guidelines

The Asthma Control Test (ACT) is more than a number — it’s a snapshot of your respiratory health. Here’s why tracking it matters:

  • Evidence-based threshold: Scores below 20 correlate with increased risk of exacerbations and reduced lung function. See research in Chest Journal.
  • Guideline-aligned action: The GINA 2024 guidelines recommend reassessment when ACT <20 — checking inhaler technique, adherence, or stepping up therapy.
  • Self-management: Regular ACT use empowers patients to spot triggers such as allergens, infections, or cold air.
  • Telemedicine ready: ACT is widely used in remote asthma management studies to guide clinician decisions.

Our tool supports global users, with ultra-fast load times, light/dark auto-theme, and accessibility-first design.

How to Pack the Asthma Control Test (ACT) Into Your Routine

Enhance your asthma care routine:

  • Weekly check-ins: Use the ACT every week or during notable symptom changes to record trends.
  • During seasonal changes: Allergens or cold weather often worsen asthma control — ACT helps you spot these fluctuations.
  • Before visits: Print or save as PDF beforehand to share with your clinician, giving them recall of your recent status.
  • Pair with other tools: Use our Symptom Checker to list symptoms, or Prescription Checker if you suspect issues with inhaler dosage.

Incorporate your ACT history into a health diary or digital tracker. Share scores with your care team to align on next steps—this strengthens adherence and outcomes.
