Background. To address the cause(s) of the significant differences in chloride (Cl-) concentrations between point-of-care blood gas analyzers and central laboratory analyzers.Methods. Cl-concentrations measured simultaneously by a blood gas analyzer (ABL800 FLEX) and a central laboratory analyzer (Hitachi7600) were collected in patients with severe acidemia (pH<7.20) (n=32) and were examined for correlations between differences in Cl-and factors associated with the acid-base status. Cl-concentrations were measured with both analyzers for samples with different concentrations of lactate, inorganic phosphate, or bicarbonate (HCO3   −).Results. The differences in Cl-concentrations were correlated withHCO3   −concentrations (r=0.72,P<0.0001) and anion gap (r=0.69,P<0.0001). Only the addition ofHCO3   −proportionately increased Cl-levels measured by a Hitachi7600, but it did not affect those measured by an ABL800FLEX.Conclusion. Cl-measurements with some analyzers may be influenced byHCO3   −concentrations, which could result in the observed discrepancies.

AbstractObjective: Measurements of electrolyte levels made by blood gas analyzers or routine methods based on membrane and selective electrodes are expected similar performance characteristics that do not show significant differences. It is clinically important that those measurements should give equivalent results and confirm the closeness to the absolute value. In this study, it was aimed to compare sodium (Na), potassium (K), chlorine (Cl), hemoglobin (Hb) and hematocrit (Hct) values measured with blood gas analyzer and standard automatic devices in the laboratory (lab) from venous blood samples.Methods: A prospective, randomized study was conducted in simultaneous venous samples from antecubital regions of patients admitted to emergency department for various reasons, were analyzed for Na, K, Cl, Hb and Hct values on blood gas analyzer and standard automatic devices in the lab. The obtained data were compared statistically.Results: A total of 100 patients were included in the study. A statistically significant correlation was found between laboratory and venous blood gas (vbg) Na, K, Cl, Hb and Hct values (p<0.001). The average difference between them was -7.9 mEq/L (r=0.720) for Na, 0.5 mEq/L (r=0.785) for K, -5.1mEq/L (r=0.790) for Cl, -0.14 grams/dL (r=0.757) for Hb and -% 1.54 (r=0.749) for Hct, respectively. Their correlation was formulated (Lab Na=vkg Nax0.621+46.081; Lab K=vkg Kx0.23+1.977; Lab Cl=vkg Clx0.847+11.050; Lab Hb=vkg Hbx0.583+5.015; Lab Hct=vkg Hctx0.565+15.024).Conclusion: In our study, it was detected that there is a statistically significant positive correlation between venous blood Na, K, Cl, Hb and Hct values of blood gas analyzer and standard automated devices in lab, and closeness of the desired performance is provided.

Introduction: Electrolyte and hemoglobin measurement are the integral part of management of critically ill patient. There can be a wide variation in the electrolyte and hemoglobin measurement in critically ill patient between arterial blood gas analyzer and central laboratory auto analyzer. Objective: To compare the electrolytes (sodium, potassium and chloride) and hemoglobin level measured by arterial blood gas analyzer and laboratory analyzer. Methodology: This was a prospective cross-sectional comparative study comparing the electrolytes (sodium, potassium and chloride) and hemoglobin measurement between arterial blood gas analyzer and laboratory auto analyzer. The study included 124 paired blood samples from the patient admitted in intensive care unit of Birat Medical College Teaching Hospital in two months duration. The arterial sample and venous sample for electrolytes and hemoglobin measurement were taken simultaneously or not more than one hour apart and analysis was done by arterial blood gas analyzer and central laboratory auto analyzer accordingly. The values of electrolytes and hemoglobin measured by two different analyzers were finally compared for variation. Result: The mean difference calculated for sodium potassium and chloride in ABG machine and Auto-analyzers were 0.57 mmol/l.-0.04mmol/l and 1.71mmol/l respectively. These data were within the acceptable range of United States Clinical Laboratory Improvement Amendments(USCLIA). The mean difference derived for hemoglobin in ABG and Auto-analyzers was 0.16g/dl which was not consistent with the range of United States Clinical Laboratory Improvement Amendments (USCLIA) Conclusion: The measurement of electrolyte namely sodium, potassium and chloride in ABG machines and Auto-analyzers of central lab were comparable while hemoglobin was not comparable under the USCLIA guidelines.
