Clinical Significance
The most reliable tests for differentiating between the transudates and exudates are the simultaneous analysis of pleural fluid and serum from lactic dehydrogenase (LD) and total protein levels. The main usefulness in defining serous body fluids as a transudate or exudate is to determine which effusions need further laboratory evaluation.
