How does lipemia affect hemoglobin
WebJan 22, 2024 · Hemolysis does not affect the total hemoglobin in the blood sample. Thus, by detecting the free hemoglobin in the plasma, we can quantify the red blood cells affected by hemolysis. In this study, we have suggested a new correction formula, which can be used to correct the deviation caused by hemolysis to the parameters of red blood cells. WebAfter hemolysis, lipemia is the most frequent endogenous interference that can influence results of various laboratory methods by several mechanisms. The most common preanalytical cause of lipemic samples is inadequate time of blood sampling after the meal or parenteral administration of synthetic lipid emulsions.

WebJan 1, 2015 · Background: Clinical laboratory assays can be affected by interferents like hemoglobin (Hb), lipids and bilirubin. We evaluated the effect of these interferences on pediatric samples for different chemistry assays. Further we established cut-off indices above which these interferences confound sample results.
