16 Νοε 2018 · Light’s criteria. Light’s criteria are more accurate for the diagnosis of exudative effusions. The fluid is considered an exudate if any of the following are present: The ratio of pleural fluid to serum protein is greater than 0.5; The ratio of pleural fluid to serum LDH is greater than 0.6
