LDH
  

Pleural:

Pleural fluid LDH to serum LDH ratio ≤ 0.6 or less than 2/3 the upper limit of normal serum LDH is consistent with transudative effusions, while pleural fluid LDH to serum LDH ratio > 0.6 is consistent with exudative effusions.

Peritoneal:

Ascitic fluid LDH may be useful in differentiating secondary Bacterial peritonitis from spontaneous bacterial peritonitis when at least two of three criteria are met in ascites fluid: 

  • Total Protein > 1.0 g/dL
  • Glucose < 50 mg/dL
  • LDH > upper reference limit for serum
