Abstract：Objective To analyze the correlation of hemoglobin (HGB) concentration detected by the arterial blood gas analysis and venous whole blood cell analysis. Methods 77 cases of arterial blood samples and 84 cases of venous blood samples were randomly selected and then detected respectively with ABL835 blood-gas analyzer and the Sysmex XE-5000 hematology analyzer, and the results were compared. The arterial and venous blood samples of 394 cases were drawn randomly at the same time. Then the HGB results correla-tion of these samples who undergone the blood-gas analysis and the whole blood cell analysis were analyzed. Results The precision of Sysmex XE-5000 hematology analyzer was higher than ABL835 blood-gas analyzer. The HGB results from blood-gas analyzer were all slightly higher than the hematology analyzer , and the differ-ences all had statistical significance(Pall<0.05). The arterial and venous blood HGB results of two methods all shown positive correlation (r=0.997, r=0.999, Pall<0.05). The HGB result of whole blood cell analysis was higher than blood-gas analysis at the same time, and the difference had statistical significance(P<0.05), The results of two methods shown positive correlation (r=0.992, P<0.05). Conclusion The precise results of HGB by arterial blood-gas analyzer can temporarily replace the results of hematology analyzer , and arterial blood HGB content is less about 2 g/L than venous blood according the extrapolation.
