Light's criteria for diagnosing pleural effusion. According to Light, for pleural fluid to be classified as exudate, one or more of the following criteria should be met including the pleural fluid protein's is greater than 0.5, its serum greater than 0.6, and its lactate dehydrogenase (LDH) ...

Light's Criteria are used to determine whether a pleural effusion is exudative or transudative. Satisfying any ONE criterium means it is exudative: Pleural Total Protein/Serum Total Protein ratio > 0.5 Pleural lactate dehydrogenase/Serum lactate dehydrogenase ratio > 0.6 ...
Therefore, if a patient meets Light's Criteria but has a clinical appearance suggestive of a transudative effusion, Dr. Light recommends a serum albumin − pleural albumin < 1.2 mg/dl, to confirm the effusion is exudative. However, do not use the albumin gradient alone to distinguish trans...

Purpose of review;Light's criteria combine three dichotomous tests into a decision rule that is considered positive if any one of the tests is positive. This strategy clearly maximizes sensitivity, although at the expense of specificity. Although Light's criteria identify 98% of pleural exudates, ...
Research over the past two to three years has shown that previously accepted criteria for ruling out a viable pregnancy are not stringent enough to avoid false-positive results, but it has been difficult both to disseminate this information to practitioners and to implement standardized protocols. Th...
pleural fluid analysisObjective Pleural effusions are common in pediatrics. When the etiology of a pleural effusion remains unknown, adult literature recommends the use of Light''s criteria to differentiate a transudate from an exudate. Pediatricians may rely on adult literature for the diagnostic ...
