The aim of this study is to validate the use of pleural cholesterol [PCHOL] and the pleural cholesterol/serum cholesterol ratio [P/S CHOL] for differentiating between transudates and exudates.
Previously established criteria were used to classify 50 pleural effusions as transudates [10 cases] , neoplastic exudates [20 cases] , tuberculous exudates [10 cases] , and para-pneumonic exudates [10 cases]. PCHOL values were statistically significantly increased in all exudate groups as compared to transudate group. It was concluded that determination of PCHOL and P/S CHOL is of great value for distinguishing between pleural exudates and transudates, and should be included in routine laboratory analysis of pleural effusions
