Interpretation
Pleural fluid triglyceride concentrations over 110 mg/dL are consistent with a chylous effusion. Triglyceride concentrations below 50 mg/dL are usually not due to chylous effusions.(1)
Peritoneal fluid triglyceride concentrations over 187 mg/dL are most consistent with chylous effusion.(3)
