Patients with bronchopneumonia often have symptoms such as cough, sputum, chills and fever, and blood tests may show elevated blood levels. Bronchopneumonia should be distinguished from tuberculosis, vasculitis, and pulmonary embolism. Patients with tuberculosis have more symptoms and longer duration, and PPD test and sputum looking for antacid bacteria can help to differentiate them. Vasculitis has multi-system changes, and tests such as ANCA and ENA enzyme profile can help to diagnose. Pulmonary embolism has symptoms such as chest pain, hemoptysis, and dyspnea.
