AbstractBackgroundThe aim of the present study was to compare hemoglobin (Hb) levels determined by point-of-care testing (POCT) HemoCue® and arterial blood gas analyzer using an automated hematology analyzer in critically ill geriatric patients.MethodsForty geriatric patients requiring intensive care treatment were included in the study. Arterial blood sample was analyzed using HemoCue® (HemoCue®; Hb 201+, Angelholm, Sweden) (HbHemoCueArterial), blood gas analyzer (Techno Medica, Gastat1800 series, Japan) (HbBGA) and an automated hematology analyzer (Cell Dyne 3700 System, Abbott Laboratories, USA) (HbLab) as a reference method. Capillary blood measurements were performed (HbHemoCueCapillary) using HemoCue® at bedside. Bland-Altman analysis was applied to the results.ResultsWe found a positive correlation between the Hb measurements of HemoCueCapillary, HemoCueArterial and automated hematology analyzer (r-values were 0.799 and 0.922, respectively) and p<0.001. There was also a positive correlation between the Hb measurements of blood gas analyzer and automated hematology analyzer (r = 0.878) and p<0.001. The bias and limits of agreement were 0.32 and −2.5±3.14 g/dL for the HbHemoCueCapillary, 0.64 and −1.03±2.31 g/dL for the HbHemoCueArterial and −1.2 and −4.45±2.05 g/dL for the HbBGA. Inotropic agent administration did not affect the Hb values in all groups.ConclusionsBoth HemoCueCapillary and HemoCueArterial are sufficiently accurate and correlated with automated hematology analyzer in geriatric critically ill patients if used correctly. In terms of Hb levels, arterial and capillary blood sample measurements with HemoCue® provided more clinically acceptable accuracy than blood gas analysis system.

Abstract Two different blood-gas analyzers were tested to determine the effects on blood pH measurement of changing the reference bridge solution from saturated KCl to normal saline (0.16 mol of NaCl per liter). This change, which necessitated the preparation of modified buffers equimolal in NaCl with respect to blood, virtually eliminated salt depletion of the bridge solution and improved the stability of the liquid-junction potential between the bridge solution and the sample. The instruments we used were the Corning 165 pH Blood Gas Analyzer and the Radiometer E5021 pH Electrode with PHM72 Acid Base Analyzer. Comparison of results on clinical blood samples indicates that performance with the modified bufferbridge system is the same as that obtained with the conventional scheme. Analytical performances of the Corning and Radiometer instruments for PO2 and PCO2, as well as for pH, were comparable.
