Preanalytical Considerations in Blood Gas Analysis Total Quality Issues for the Clinical Laboratory

As indicated at the outset of this report, the critical nature of the clinical requirements when blood gas testing is indicated, coupled with the labile nature of the sample and rapidly changing patient conditions makes it imperative that the analyst be aware of more than just the analysis it self Knowledge by the analyst, of the physiology of blood gas, the interpretation of basic blood gas results, the effects of the changing patient environment and the manner in which the sample is treated

Total Quality in the Clinical Laboratory is, quite simply, "the correct result on the correct patient at the correct time." Blood gas and pH analysis have "more immediacy and potential impact on patient care than any other laboratory determination."8) Shapiro8) notes that in a study involving thousands of patients, more than five percent of the individually collected specimens were questionable based on preanalytical error and, indeed, more than 15% of the specimens received from the emergency room were associated with significant pre-analytical error ! Based on these points and in order to assure total quality results, it is evident that the laboratory technologist and the manager both must be aware of the impact of not only analytical error but also pre-analytical considerations in the assessment of the reliability of results to be reported.
