A pleural fluid triglyceride concentration greater than 110 mg/dL or presence of chylomicrons is consistent with a diagnosis of chylothorax whereas a triglyceride level less than 50 mg/dL makes the diagnosis less likely. A ratio of pleural fluid cholesterol to triglyceride of less than 1 is also considered diagnostic (Chest. 2008 PMID: 18339791)
