Answer

Distinguishing pneumonia from other pulmonary pathologies, such as acute COPD or asthma exacerbation, can often present a significant challenge, particularly in patients with these underlying lung diseases. C-reactive protein (CRP) and procalcitonin values may help in distinguishing infectious pneumonia from noninfectious underlying disease exacerbations. [52]
