The ratio of pleural fluid to serum LDH is greater than 0.6. The pleural fluid LDH value is greater than two-thirds of the upper limit of the normal serum value.
Detailed explanation-2: -Protein content of less than 2% (1-2 g/dL) Fewer than 1000 white blood cells (WBCs) per cubic millimeter. Glucose content similar to that of plasma. Lactate dehydrogenase (LDH) less than 50% of plasma.
Detailed explanation-3: -In a healthy human, the pleural space contains a small amount of fluid (about 10 to 20 mL), with a low protein concentration (less than 1.5 g/dL).
