Initial analysis on pleural fluid should always include a packed cell volume (PCV), cell count, protein or specific gravity, and cytology. Smears can also be prepared for Gram staining to aid in decisions regarding empiric antibiotic therapy while awaiting culture results. Additional diagnostic tests for systemic disease such as a CBC, chemistry panel, urinalysis, or echocardiogram can be chosen after the character of the pleural fluid is determined (Table 2.6). Additional tests to perform on pleural fluid include bacterial culture and susceptibility testing (aerobic and anaerobic cultures), protein electrophoresis, or a cholesterol/triglyceride ratio for the diagnosis of chylothorax.
