Clinical Significance
Pleural fluid: transudate: protein less than 3.0 g/dL; exudate: protein greater than 3.0 g/dL; a greater than 0.5 g/dL pleural fluid to serum protein ratio is indicative of an exudate in hypoproteinemic states. Peritoneal fluid: exudate: greater than 2.5 g/dL; note: there are many exceptions to this figure.
For differentiation of transudates from exudates, test blood for protein, lactate dehydrogenase (LD), and glucose for comparison with fluid levels. Transudates (plasma ultrafiltrate) may be seen in congestive heart failure, cirrhosis, nephrosis; exudates (inflammatory response) may be seen in infections, infarcts, cancer, rheumatoid arthritis (lung), acute pancreatitis with left pleural effusion and ascites.
