Lipid emulsion solution: A novel cause of hemolysis in serum and plasma blood samples.
OBJECTIVE
After several hemolyzed blood samples were received in the laboratory, we investigated lipid emulsion/TPN as a novel cause of hemolysis.


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.


CONCLUSIONS
Collection of specimens in blood gas syringes may prevent hemolysis in patients on lipid emulsion.
