WebFeb 1, 2014 · Several preanalytical variables affect electrolyte results, including type of anticoagulant, storage conditions, and hemolysis. Hemolysis of blood causes a false increase in plasma K results by releasing intracellular K; however, grossly hemolyzed specimens will affect the analyses of Na and Cl levels due to a dilutional effect. WebTwo analytes greatly impacted by hemolysis are potassium and lactate dehydrogenase, in which their concentrations in erythrocytes are more than 20 times and 150 times higher than it is in serum, respectively. The second mechanism by which hemolysis affects test accuracy and reliability is through interference from hemoglobin itself.
WebHyperkalemia. Hyperkalemia is a serum potassium concentration > 5.5 mEq/L (> 5.5 mmol/L), usually resulting from decreased renal potassium excretion or abnormal movement of potassium out of cells.
