Asthma is a common respiratory condition that affects your breathing. It is caused by inflammation of the airways and can result in wheezing, coughing and breathing difficulties.
As well as recognising symptoms, several tests can deliver a diagnosis. The main three tests for asthma are:
For those already managing asthma, you can also test to see how well-controlled your condition is. This is called an asthma control test (ACT).
To learn about the symptoms of asthma as well as these different tests, please continue reading.
The signs and symptoms of asthma vary from person to person, but can look like any of the following:
Many different factors or conditions can cause these symptoms. However, they are more likely to be caused by asthma if they:
Asthma can develop at any point in one’s life. If you have been experiencing any of the above symptoms, it’s best to get tested so you can receive a diagnosis.
If you want to take an asthma test, book an appointment with your doctor. They can then perform one or more of the following procedures.
A peak flow test is the most basic type of asthma test. It measures how quickly you can blow air out of your lungs.
You perform this test by blowing into a handheld device called a peak flow meter. These are available at most pharmacies, which means you can also perform the test at home.
Instructions for using a peak flow meter are as follows:
If you can’t exhale air quickly enough, this may indicate that your airways are narrowed and that you need to start taking asthma medicine.
Another type of asthma test involves using a spirometer. This is a small machine that is attached to a mouthpiece via a cable.
As well as asthma, it can be used to diagnose other lung conditions including:
A spirometry test works similarly to a peak flow test. It measures how much air you can exhale in one forced breath.
A spirometry test will look like the following:
Spirometry test results don’t usually come back immediately. A doctor or specialist will analyse your results before deciding on your diagnosis.
A FeNO test (fractional exhaled nitric oxide test) detects asthma based on how much nitric oxide you exhale.
Exhaling too little nitric oxide can indicate a certain level of inflammation in the lungs. As a result, the patient may benefit from asthma medication.
A FeNo test is easy to do and completed with a small hand-held device.
Your results will show up on the screen of the device straight away.
Please note: Avoid eating any foods containing nitrates (such as leafy greens and vegetables) for at least 3 hours before a FeNO test to ensure a reliable reading.
People with asthma may find that their symptoms worsen from time to time. This is normal and usually happens due to certain triggers like pollen, mould, humidity or exercise.
However, if your symptoms don’t return to normal after a flare-up, this can indicate that your asthma is worsening or becoming more severe.
If this applies to you, it’s important to visit a GP or asthma nurse. You’ll need to get the correct treatment to avoid severe symptoms and prevent asthma attacks.
In general, your asthma is well controlled if:
If one or more of these points doesn’t apply to you, you should visit a healthcare professional. Based on your symptoms, they may adjust your treatment so that you feel more in control of your asthma.
If you’ve noticed changes in your condition, you can also perform an Asthma Control Test (ACT).
This test asks you several questions about how your asthma has affected you within the past four weeks.
It will ask about your sleep quality, any disturbances at work, how often you use your reliever inhaler, and if you feel in control of your breathing.
If the test tells you that your symptoms aren’t being well-managed, your doctor may need to make changes to your asthma treatment.
Overall, you should visit your doctor or a healthcare professional if:
