About the Asthma Control Test (ACT) score

Measuring baselines and outcomes with the ACT score.

Written by Allie

Every patient who has been diagnosed with Asthma will be assessed for a baseline Asthma Control Test (ACT) score. If you've been diagnosed with Asthma and are tracking your treatment with our app, you've probably noticed a number called the ACT score next to your progress chart.

What is the ACT?

The Asthma Control Test (ACT) is a short questionnaire about how your asthma has been affecting your daily life recently (i.e. shortness of breath, nighttime symptoms, use of rescue inhalers, and how in-control you feel overall). It's one of the most widely used tools for measuring asthma control, both in research and in everyday clinical care.

How is it scored?

The ACT includes 5 questions, each scored from 1 to 5, for a total score between 5 and 25. A score of 20 or higher generally means your asthma is well-controlled. A score below 20 classifies your asthma as uncontrolled.

Why is the ACT so important to us?

Treating your allergies while your asthma is uncontrolled requires additional steps and an alteration to your treatment plan to ensure safety and comfort. In most cases, we will want to work with you to get your ACT score above 20 before starting treatment. The ACT score helps us identify patients with uncontrolled asthma who require this additional intervention.

Your ACT score helps us track your progress over time. If your score is trending upward, that's a good sign your treatment plan is working. If it drops or stays low, that's automatically flagged to our care team, who will follow up with you and adjust your treatment if needed. The ACT gives you and our clinicians an objective and consistent way to see how your treatment is working over time so that there is no guesswork involved.
