Testing For Asthma
If you are feeling under the weather and think that you may have similar symptoms to that of asthma, then you will need to gather more in detail information about the illness. The internet offers simple 30 second tests which can be taken online giving a better idea whether you are suffering form asthma or not. These tests are not diagnostic tests and visiting your doctor is the only way of knowing if you are suffering from asthma.
The doctor will diagnose asthma mostly from the symptoms you show and your family history. Most people who are allergic to certain allergens and have a history of asthma in their family, will develop into asthma. The diagnosis is confirmed with the help of asthma tests that measure the airway function, the lung function and so on.
Not all asthma tests are applicable to children. In fact, the majority of asthma tests cannot be carried out in children below 4 years old because they cannot understand or act on instructions. The most common asthma tests would need a certain level of comprehension and cooperation from the one being tested in order to carry out the test accurately. In these cases, the doctor would rather go by the symptoms and clinical signs the child projects. Their reaction to an inhaled bronchodilator is also measured and used in the diagnosis making process.
In adults however, things are much simpler. There are a number of asthma tests such as peak flow tests at rest (and after exercise) and lung function tests which are usually sufficient to make an accurate diagnosis. Once the diagnosis has been reached, it is important to learn about the severity of the disease so the treatment can be worked out.
The most common tools used for diagnosing asthma are the peak flow meter and spirometry.
The peak flow meter is a small device which is mostly used to measure the speed of the air flow as it moves through the lungs. The meter is able to detect the restriction degree in the air passages and it is used to record the highest reading indicating the maximum capacity of the patient to expel air from his or her lungs. This reading would be compared with the other readings and thus the severity of the disease can be found.
Another tool which is used to test the severity of asthma in adults is Spirometry. This tool is used in the lung function test, and also the reversibility test or the post BD (bronchodilation) test. Both of these tests give very accurate results and are very important when trying to make an asthma diagnosis.
