Reference Values
An interpretive report will be provided.
Interpretation
Pleural Fluid:
Pleural fluid cholesterol concentrations 46 to 65 mg/dL are consistent with exudative effusions.
Cholesterol concentrations greater than 200 mg/dL suggest pseudochylous effusion.
Triglyceride concentrations greater than 110 mg/dL are consistent with chylous effusions.
Triglyceride concentrations less than 50 mg/dL are usually not due to chylous effusions.
Peritoneal Fluid:
Peritoneal fluid triglyceride concentrations greater than 187 mg/dL are most consistent with chylous effusion.
Cholesterol concentrations 33 to 70 mg/dL suggest malignant causes of ascites.
