Distinguishing between chylous and nonchylous effusions
Measurement of triglycerides in body fluids as a surrogate for chylomicrons
Method Name
Colorimetry
Ordering Guidance
For help distinguishing between chylous and nonchylous effusions, order BFLA1 / Lipid Analysis, Body Fluid. The body fluid will be tested for cholesterol and triglyceride concentrations and undergo lipoprotein electrophoresis.

Reference Values
An interpretive report will be provided.
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)
