Diagnosing respiratory conditions involves a thorough assessment, starting with a detailed medical history and physical examination to understand symptoms, lifestyle factors, and overall health. Pulmonary function tests, including spirometry and specialized assessments, evaluate lung function and airway responsiveness. Imaging techniques like X-rays, CT scans, and MRIs provide detailed views of lung structure and potential abnormalities. When necessary, biopsies are performed to analyze lung tissue or lymph nodes, aiding in precise diagnosis and treatment planning tailored to each patient’s needs and condition severity.
