Sažetak
Background: The aim of this study was to compare haemoglobin and haematocrit levels measured as point of care testing and measurements done by automated haematology analyzer. Materials and methods: In this prospective study, haemoglobin and haematocrit levels were measured in 126 consecutive paired arterial or capillary samples using a point of care blood gas analyzer and automated haematology analyzer. Pearson correlation coefficient and Passing-Bablok regression were calculated for the data comparison. Results: Mean (SD) level of haemoglobin measured on blood gas analyzer was 135.59 g/L (26.48) and measured on automated haematology analyzer 118.84 g/L (25.59). The mean difference between the blood gas analyzer and automated haematology analyzer was -16.75 g/L (P < 0.001). Mean (SD) level of haematocrit measured on blood gas analyzer was 0.399 L/L (0.078) and measured on automated haematology analyzer 0.356 L/L (0.071), respectively. The mean difference between the blood gas analyzer and automated haematology analyzer was -0.043 L/L (P < 0.001). Comparison of the results of two devices yielded correlation coefficients r = 0.98 (P < 0.001) for haemoglobin and r = 0.75 (P < 0.001) for haematocrit. Conclusions: Although the correlations between the measurements were significant, blood gas analyzer has shown unacceptable agreement with automated haematology analyzer. It overestimates haemoglobin and haematocrit values, which is not clinically acceptable.
