VETlabs Peritonitis Detection Kit, which is developed and manufactured by Bioguard Corporation, can differentiate a transudate from an exudate. When the exudate contains reaction-positive proteins, it forms an effusion drop, which precipitates in the reaction solution. The formation of precipitated products, teardrop-shaped, mists or smears can be observed during the test. In contrast, the transudate will completely dissolve in the reaction solution during the sedimentation. Each box contains 6 test kits including 6 reaction tubes with acetic acid solution, 6 droppers, 6 dye-containing tubes and an instruction manual.
