Lipid Analysis, Body Fluid
Use
The test is useful for distinguishing between chylous and nonchylous effusions by measuring cholesterol and triglycerides and detecting chylomicrons in body fluids. Chylous effusions, which contain chylomicrons, may appear milky due to the presence of chyle in the lymphatic system, often linked to malignancy or trauma. Pseudochylous effusions can resemble chylous effusions but do not contain chylomicrons, instead having elevated cholesterol. Differentiating between these can inform appropriate therapeutic management strategies.
Special Instructions
