Thoracentesis involves obtaining a sample of the pleural fluid that has accumulated in the pleural space. This sample can be sent for microbiological testing to determine the causative agent of the empyema. Blood tests (CBC) may show signs of infection, but will not identify the specific microorganism responsible. Computed tomography can help diagnose an empyema, but does not provide information on the causative agent. Sputum culture is used to diagnose respiratory infections, but is not typically used to diagnose empyema.
