Detailed • Mobile-ready

Inputs

This tool follows an ACT-style 5-question scoring pattern for the last 4 weeks and adds extra interpretation, but it does not replace a clinician review, inhaler technique check, or a written asthma action plan. Good control usually means few symptoms, little reliever use, minimal night waking, and little activity limitation. [web:81][web:82][web:86]

      How to use this tool

      • Answer the 5 control questions based on the last 4 weeks.
      • Use the score together with reliever use, night waking, and activity limitation to understand the pattern more deeply.
      • Add the extra asthma clues if recent attacks, missed preventer doses, or obvious triggers apply.
      • Use the CSV export if you want to keep a written result summary.
      • Remember that changing inhaler technique, adherence, and trigger exposure can change control even if the prescription stays the same.

      When extra care is needed

      • Your reliever inhaler is not helping or you need it very frequently.
      • You are wheezing a lot, very breathless, struggling to walk or talk, or waking repeatedly with symptoms.
      • You recently had an asthma attack or needed emergency or hospital care.
      • You are using more reliever inhaler and falling behind in normal daily activity.
      • You are getting worse quickly or your breathing feels hard work. [web:83][web:85][web:87]
      The standard ACT uses 5 questions scored 1 to 5 over the last 4 weeks, and score interpretation commonly groups 20 to 25 as better control, 16 to 19 as not well controlled, and 5 to 15 as very poor control. [web:82][web:86][web:88]

      Take the Asthma Control Test (ACT) — the trusted, validated 5-question self-assessment to quickly estimate how well your asthma is controlled. Our free online ACT calculator gives you instant results (score 5–25), clear interpretation, and next steps based on medical guidance like GINA guidelines. Designed for speed and clarity, this Asthma Control Test (ACT) provides a seamless experience across all devices.


      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.
