title: Erroneous classification of a pleural effusion. The role of a traumatic thoracentesis.
abstract: The separation of pleural effusions into exudates and transudates is based on the pleural fluid LDH and protein content compared to the simultaneous serum LDH and protein content. A patient in biventricular failure presented with a right pleural effusion that met the criteria of a transudate. After a traumatic thoracentesis the fluid met the criteria of an exudate.
