Lipid emulsion solution: A novel cause of hemolysis in serum and plasma blood samples
Objectives:
After several hemolyzed blood samples were received in the laboratory, we investigated lipid emulsion/TPN as a novel cause of hemolysis.
Design And Methods:
Whole blood was spiked with lipid emulsion and TPN.
Results:
Hemolysis was proportional to the amount of lipid emulsion present in whole blood, with less hemolysis occurring in blood gas syringes compared to vacutainer tubes.
Conclusion:
Collection of specimens in blood gas syringes may prevent hemolysis in patients on lipid emulsion.

Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...
