Triglycerides, Body Fluid
Distinguishing between chylous and nonchylous effusions
Determining if bleeding has occurred in a body fluid
Identifying iatrogenic effusions
Clinical Information Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test
The presence of a chylous effusion, which results from lymphatic drainage into a body cavity, can be determined by identifying triglycerides and chylomicrons in the fluid.
Catheter-related iatrogenic effusions can be identified by determining the presence of intravenous solution constituents in the fluid.
Reference Values Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.
Triglyceride concentration >110 mg/dL is highly suggestive of a chylous effusion.
Cautions Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances
Cannot be performed on viscous fluids
Clinical Reference Provides recommendations for further in-depth reading of a clinical nature
