Rivalto's test
Rivalt's test is a method used to differentiate transudate and exudate, eg in ascitic fluid or hydrothorax.
The test is carried out using a solution acetic acid and is negative for transudative fluid. The transudate disperses in the solution while the exudate precipitates. Inflammatory effusion contains acute phase proteins such as C reactive protein, ceruloplasmin, fibrinogen and others, so a positive Rivalt test may indicate ongoing inflammation.
