How Are COPD and Asthma Diagnosed?
Diagnosing COPD and asthma requires a thorough evaluation of symptoms, medical history, and lung function. For both conditions, healthcare providers typically begin with a detailed patient history, including smoking habits, exposure to irritants, family history of respiratory diseases, and symptom patterns. A physical examination may reveal signs such as wheezing or prolonged expiration, which can provide clues about the underlying condition.
Pulmonary function tests, such as spirometry, are essential tools for diagnosing both COPD and asthma. Spirometry measures how much air a person can exhale and how quickly, helping to assess airway obstruction. In asthma, airway obstruction is often reversible with the use of bronchodilators, while in COPD, it is usually persistent and progressive. Additional tests, such as chest X-rays, CT scans, or blood tests, may be used to rule out other conditions and confirm the diagnosis. Allergy testing may also be performed in asthma patients to identify potential triggers.
