Transudates are fluids that pass through a membrane or squeeze through tissue or into the extracellular space of tissues. Transudates are thin and watery and contain few cells or proteins.[1]

To tell exudates apart from transudates, the patient's serum is taken and tested. If total protein is normal and the pleural fluid protein is < (less) than 25g/L the fluid is a transudate. Also, if the pleural fluid protein is > (higher) than 35g/L the fluid is an exudate.[1] Transudate is usually clear also. The appearance is used in diagnosing the liquid when it comes out before testing.
