Physical Exam
To rule out some possible issues that are quite similar to asthma, such as COPD or respiratory infection. Your doctor might need to do some physical exams. The most common option is a pulmonary or lung function test. This will help measure the amount of air that you can inhale and exhale. Based on this information, your doctor would figure out the current conditions and design a proper treatment plan. Physical exams should be performed after or before taking a bronchodilator to open up the air passages. [3]
