Test Code Billings Clinic:9809 Mayo:CHLBF Cholesterol, Body Fluid
Reporting Name
Cholesterol, BFPerforming Laboratory
Mayo Clinic Laboratories in RochesterUseful For
Aiding in the diagnosis of a cholesterol effusion or cholesterol-rich pseudochylous effusion in body fluids
Distinguishing between chylous and pseudochylous pleural effusions
Distinguishing between malignant and nonmalignant ascites
Method Name
Colorimetry
Ordering Guidance
This test provides a measurement of cholesterol in body fluids, which is useful for screening of a cholesterol effusion or cholesterol-rich pseudochylous effusion. To distinguish between chylous and nonchylous effusions, order BFLA1 / Lipid Analysis, Body Fluid; which measures cholesterol and triglyceride concentrations, as well as chylomicrons and plasma lipoproteins.

Reference Values
An interpretive report will be provided.
Interpretation
Pleural fluid cholesterol concentrations between 46 to 65 mg/dL are consistent with exudative effusions. Cholesterol concentrations above 200 mg/dL suggest a pseudochylous effusion.(2)
Peritoneal fluid cholesterol concentrations between 33 to 70 mg/dL suggest a malignant cause of ascites.(4)
