LOINC Group Usage Notes

Several authors have studied agreement between arterial and venous blood measurements of potassium with blood gas analyzers and found good intra-patient agreement.[PMID:15788827][PMID:25859448][PMID:25885983] However, it is important to remember that the concentration of key electrolytes is influenced by the presence of hemolysis. In vitro hemolysis of red cells in a blood sample will cause release of K+ from RBCs and may produce an artefactual hyperkalemia. Laboratory assays of venous samples are screened for hemolysis, but blood gas electrolyte measurementsmay not be.[PMID:23314547][PMID:23724399]
