Evaluation of Pleural Effusion Type Determination Based on Light's and Heffner's Criteria

Pleural effusion is an abnormal accumulation of pleural fluid in the cavity due to excessive transudation or exudation. Light's criteria used as standard method distinguish between exudates and transudates. Some recent studies reported misclassifications which led development several alternative criteria, such Heffner's criteria. The purpose this study was determine sensitivity specificity type effusion. This research observational with a cross-sectional using patients at Clinical Pathology Laboratory Installation Wahidin Sudirohusodo Hospital July 2018. Total protein, LDH, cholesterol levels were measured all samples that met inclusion exclusion There 45 consisted 30 transudate 15 exudate samples. Based on clinical diagnosis, showed 3 obtained 2 misclassifications. data above, statistical had 96.7% 86.7%. 100% can be because it better than
