No conflicts of interest reported. The total protein (TP) concentration and cell count of pleural and abdominal fluid is used to differentiate a transudate from an exudate. TP can be measured by automated wet chemistry analyser or more easily using a refractometer. The aim of this study was to assess if refractometer values of TP are useful for this purpose. Retrospectively samples from canine pleural and abdominal effusions in which TP concentration was measured both with a refractometer as well using Pentra 400 (ABX Horiba, Montpellier) were included. Samples were collected into heparinized tubes and analysed within 12 hours. Bland-Altman diagrams were created and correlation between both measurements was calculated by Spearman 0 s nonparametric correlation.
