Positive Rivalta test of a FIP-Aspiration. For visualisation the fluid was colored by Methylenic blue.
Certain diseases can cause excessive accumulations of fluid in areas of the body such as the abdomen (ascites) or the pleural space around the lungs (pleural effusion) or the pericardial space around the heart. An estimate of the concentration of protein in such fluids can narrow the differential diagnosis and assist the clinician in establishing a diagnosis. For example, fluid accumulations due to congestive heart failure and liver failure (cirrhosis) are typically lower in protein content and are called transudates whereas fluid accumulations due to cancer and tuberculosis are typically higher in protein content and are called exudates. The Rivalta Test is a simple, inexpensive method that can be used in resource-limited settings to differentiate a transudate from an exudate.[1] It is a simple, inexpensive method that does not require special laboratory equipment and can be easily performed in private practice. The test was originally developed by the Italian researcher Rivalta around 1900 and was used to differentiate transudates and exudates in human patients. It is also useful in cats to differentiate between effusions due to feline infectious peritonitis (FIP) and effusions caused by other diseases.[2] Not only the high protein content, but high concentrations of fibrinogen and inflammatory mediators lead to a positive reaction.
