Transudates are caused by disturbances of hydrostatic or colloid osmotic pressure, not by inflammation. They have a low protein content in comparison to exudates and thus appear clearer. [6] Levels of lactate dehydrogenase (LDH) [7] or a Rivalta test can be used to distinguish transudate from exudate. [citation needed]
For example, the specific gravity of the transudate is usually less than 1.012 and a protein content of less than 2 g/100 mL (2 g%). Rivalta test may be used to differentiate an exudate from a transudate. It is not clear if there is a distinction in the difference of transudates and exudates in plants.

A pleural effusion is accumulation of excessive fluid in the pleural space, the potential space that surrounds each lung.Under normal conditions, pleural fluid is secreted by the parietal pleural capillaries at a rate of 0.6 millilitre per kilogram weight per hour, and is cleared by lymphatic absorption leaving behind only 5–15 millilitres of fluid, which helps to maintain a functional ...
Ascitic fluid can accumulate as a transudate or an exudate. Amounts of up to 35 liters are possible. Roughly, transudates are a result of increased pressure in the hepatic portal vein (>8 mmHg, usually around 20 mmHg [18] (e.g., due to cirrhosis), while exudates are actively secreted fluid due to inflammation or malignancy.
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 serum-ascites albumin gradient or gap (SAAG) is a calculation used in medicine to help determine the cause of ascites. [1] The SAAG may be a better discriminant than the older method of classifying ascites fluid as a transudate versus exudate.
Exudates and transudates [ edit ] Measuring LDH in fluid aspirated from a pleural effusion (or pericardial effusion ) can help in the distinction between exudates (actively secreted fluid, e.g., due to inflammation ) or transudates (passively secreted fluid, due to a high hydrostatic pressure or a low oncotic pressure ).
