Triglycerides, Body Fluid
Use
Triglyceride concentration in body fluids is correlated with the presence of chylomicrons and can be useful when diagnosing chylous effusion or differentiating from pseudochylous effusion. Chylous effusions contain chylomicrons and are indicative of disruptions in the lymphatic system, often due to malignancy or trauma. Elevated triglyceride concentrations, above certain thresholds, are consistent with chylous effusions and assist in distinguishing between chylous and nonchylous effusions.
Special Instructions
Not provided.
Limitations
The test may yield false-low results in the presence of therapeutic concentrations of Dicynone (Etamsylate) and the acetaminophen metabolite, N-acetyl-p-benzoquinone imine. Additionally, in rare cases, gammopathy, particularly type IgM (Waldenstrom macroglobulinemia), may cause unreliable results.
