Overview
Laboratory Findings
Diagnosis is confirmed by thoracentesis; frank pus may be aspirated from the pleural space. The pleural fluid typically has a low pH (<7.20), low glucose (<60 mg/dL), and contains infectious organisms. Therefore, the diagnosis relies on the presence of pus or organisms on gram stain.
A positive bacteria culture from pleural fluid is not needed to make diagnosis of empyema.[1][2]
