The pathologic accumulation of fluid inside pleural, peritoneal and pericardial cavities is called cavitary effusion. Many kinds of etiologies and different mechanisms related with the formation of this entity has been described. The laboratorial analysis of body fluids (BF) is composed by physical assessment, biochemical measurements and cytological examination. The parameters obtained during these steps of the BF analysis can be used to classify the effusion and, thus, detect the underlying etiology and/or its formation mechanism. In Veterinary Medicine, general and specific systems of classification have been described. The general classification considers total protein concentration (TPC), total nucleated cell count (TNCC), cell type predominance and allows it to include the effusion into three possible categories: pure transudates, modified transudates and exudates. Different intervals for TPC and TNCC as well as different concepts regarding the cell type predominance in each of these categories have been proposed by multiple authors. In a retrospective study, data from 304 BF analysis obtained from 246 dogs presenting with cavitary effusion, consulted at the Veterinary Hospital of UFMG was collected in order to comprehend the laboratorial and epidemiological aspects of these cases, by comparing the data obtained with the main scientific publications regarding this subject. The criteria proposed by Stockham and Scott (2008) for the general classification of canine cavitary effusions showed the highest efficacy in associating the kind of effusion with the expected type of underlying etiology. Their propositions about the cell type predominance in each kind of effusion also showed a higher agreement with the results obtained in this study.
