Pleural Fluid Analysis (Light's Criteria)

Type	Criteria	Etiology
Transudate	P/S Protein < 0.5 AND LDH Ratio < 0.6	CHF, Cirrhosis, Nephrotic
Exudate	P/S Protein > 0.5 OR LDH Ratio > 0.6	Pneumonia, TB, Malignancy

Light’s Criteria, is the gold standard for differentiating Exudates from Transudates.

An effusion is an EXUDATE if it meets at least one of the following

Protein Ratio : Fluid Protein / Serum Protein > 0.5

LDH Ratio : Fluid LDH / Serum LDH > 0.6

LDH Absolute Value : Fluid LDH > 2/3 the upper limit of normal for Serum LDH.

Please correlate clinically.
