Separating Exudates From Transudates

Objectives: To evaluate the usefulness of diverse combinations of pleural cholesterol concentration, pleural or serum protein, and lactate dehydrogenase (LDH) levels for the differentiation ofpleural exudates and transudates. Design: Prospective laboratory study of pleural effu¬ sions. Setting: Medical school hospital. Patients: One hundred eighty consecutive internal medicine ward patients in ...

The distinction between transudates and exudates.

The first step in the diagnosis of pleural effusions is the distinction between exudates and transudates. The aim of this study was to evaluate the usefulness of various parameters for the differentiation of pleural exudates and transudates. We recorded clinical characteristics, final diagnoses, and measured pleural fluid and serum levels of albumin, protein, LDH, cholesterol, and bilirubin of ...

Drawing the line: differentiating transudates from exudates.

Accessible online at: www.karger.com/journals/res Involvement of the pleural mesothelium in inflammatory disease processes results in the development of an exudative pleural effusion. When the pleura itself is not inflamed and there is increased intravascular pressure, transudative effusions occur. This important concept is clearly illustrated in the paper by Alexandrakis and Bouros [1] in this...
