asthma-testAsthma is a tendency of hyper-reactive airways in children. The disease is a form of allergy to suspended airborne particles in the atmosphere. Many allergens in the environment such as dust, mites, smoke, atmospheric pollutants and chemicals can trigger an asthma attack. Typically it worsens during winters

Asthma manifests predominantly with cough, particularly at night. Bouts of cough are followed by vomiting of sticky white mucus. In most children, a good history and physical examination suffices to accurately diagnose Asthma in children by the pediatrician.

Asthma Tests to Confirm Diagnosis:

To confirm the diagnosis, simple blood tests and a chest X ray is all that is needed.

Allergen Testing: In a small subset of children where a strong allergic basis exists, allergen testing is necessary.

Pulmonary function tests (PFT) also called as Lung function tests can be done to diagnose the condition in older children with asthma.

In infants, however recurrent wheezing and symptoms suggestive of Asthma can be due to other reasons such as gastroesophageal reflux disease, or congenital structural abnormalities of the trachea and esophagus.

Lung Function Tests: Lung function tests check the status of working condition of your lungs. It determines the capability of your lungs to hold air and quickly move air in and out of your lungs, and the capacity to put oxygen into the blood and remove carbon dioxide from your blood. The tests can also diagnose if there are any lung diseases, and check the response of the body to the treatment.

Some other PFT tests include residual volume, gas diffusion tests, body plethysmography, inhalation challenge tests, and exercise stress may also be done to determine lung function.

  • Spirometry: It is one of the most common tests done to diagnose Asthma. It measures the amount of air and the speed at which the air is moved in and out of the lungs.
  • Peak expiratory flow (PEF):  This test is needed when you have symptoms off and on but have normal spirometry test results. This test is used to understand the condition of the airways in people who have asthma or other conditions that affect breathing. The daytime changes in PEF may be done over 1 to 2 weeks.
  • Exercise Challenge Test is usually done if Asthma is suspected even though the spirometry test results are normal or almost normal. It measures how quickly you can breathe in and out after an exercise. Another inhalation challenge test is also done using a specific allergen to check for occupational asthma if suspected.

Prevention is the best way to stay clear of asthma, unless it is congenital, caused by family history. To reduce flare up of asthma, clean surroundings, control of house dust, mites, animal danders, etc.
