Interpretation

Pleural: Pleural triglycerides <50 mg/dL excludes a chylothorax. Pleural triglycerides >110mg/dL supports a diagnosis of a chylothorax.

 

Peritoneal/Ascites: Peritoneal fluid triglyceride values greater than 110 mg/dL have been suggested for diagnosis of chylous ascites. Measurement may also be useful in distinguishing cirrhotic versus malignant origins.

 

Drainage: The reference range has not been established for this fluid specimen. The fluid results should be compared with the concentration in serum/plasma or integrated into the clinical context for interpretation.
