Light's criteria

Criteria which help differentiate pleural exudates and transudates
Light's criteria for exudates–any of following
Pleural fluid/serum protein ratio > 0.5
Pleural fluid/serum LDH ratio > 0.6
Pleural fluid LDH >23 the normal upper limit for serum

Pleural fluid LDH greater than two thirds of the upper limits of normal serum value
Pleural fluid LDH >60 percent of upper limit for serum
We noticed that there were significant linear correlation between age and pleural fluid glucose level, pleural fluid protein and serum protein, pleural fluid LDH and serum LDH and pleural fluid glucose and pleural fluid cholesterol.
LC-2: The ratio of pleural fluid LDH to serum LDH is greater than 0.
LC -3: The pleural fluid LDH level is greater than two thirds of the upper limit of normal for serum LDH (1).
3) Pleural fluid LDH greater than two thirds the upper limits of normal of the serum LDH.
6, or (3) a pleural fluid LDH value greater than 200 IU/L (international units per liter).
6, and the pleural fluid LDH activity be >200 U/L.
There were significant correlations between pleural fluid [beta]-globin DNA concentration and pleural fluid LDH activity [r = 0.
The significant correlations of pleural fluid [beta]-globin DNA concentration with the pleural fluid LDH activity and total protein concentration imply that cell-free DNA, LDH, and total protein arise by similar mechanisms through cell death and the subsequent release of the intracellular contents into the pleural cavity.
33, a pleural fluid LDH of 99 U/L, and a pleural/serum LDH ratio of 0.
18; and pleural fluid LDH, 47 U/L), but the PZE classified it as an exudate ([alpha]-2 and [gamma] bands present).
