Abstract
|
|
|
Background: A handheld blood gas analyser has been newly developed for mobile monitoring of blood gasses and electrolytes. We evaluated the performance of a portable blood gas analyser, EpocTM (Epocal Inc., Canada) according to Clinical and Laboratory Standard Institute (CLSI) guidelines, and compared it to that of a conventional analyser used in clinical laboratories.
Methods: Precision and percent carry-over were determined using three levels of aqueous and hematocrit control materials according to CLSI EP10-A3. Linearity was determined using five levels of control materials according to CLSI EP6-A. The pH, pCO2, pO2, Na+, K+, Ca2+, glucose,lactate, and hematocrit levels were compared between the EpocTM and Stat Profile Critical Care Xpress (STP CCX; Nova Biomedical, USA) analysers using whole blood samples from 40 subjects according to CLSI EP9-A2.
Results: Precision and percent carry-over were determined using three levels of aqueous and hematocrit control materials according to CLSI EP10-A3. Linearity was determined using five levels of control materials according to CLSI EP6-A. The pH, pCO2, pO2, Na+, K+, Ca2+, glucose,lactate, and hematocrit levels were compared between the EpocTM and Stat Profile Critical Care Xpress (STP CCX; Nova Biomedical, USA) analysers using whole blood samples from 40 subjects according to CLSI EP9-A2.
Conclusion: Precision and percent carry-over were determined using three levels of aqueous and hematocrit control materials according to CLSI EP10-A3. Linearity was determined using five levels of control materials according to CLSI EP6-A. The pH, pCO2, pO2, Na+, K+, Ca2+, glucose,lactate, and hematocrit levels were compared between the EpocTM and Stat Profile Critical Care Xpress (STP CCX; Nova Biomedical, USA) analysers using whole blood samples from 40 subjects according to CLSI EP9-A2.
