摘　　要：目的研究血细胞分析仪与血气分析仪红细胞压积与血红蛋白测定结果是否存在差异。方法对32例住院患者采集肝素抗凝动脉血和EDTA-K2抗凝动脉血,采用OMIN-C型血气分析仪测定肝素锂抗凝动脉血红细胞压积与血红蛋白,EDTA-K2抗凝动脉血在XT-1800i血细胞分析仪上进行检测。结果血细胞分析仪精密度较好,所有结果符合CLIA′88允许误差要求,血气分析仪测定的红细胞压积与血红蛋白均高于血细胞分析仪测定结果,差异有显著统计学意义(P<0.01)。结论血气分析仪检测血红蛋白与传统方法明显不同,结果有显著差异,有必要建立适合血气分析仪的红细胞压积与血红蛋白生物参考区间。Objective To explore the difference of hematocrit and hemoglobin results between blood cell analyzer and blood gas analyzer.Methods 32samples were acquired from patients in the hospital.The EDTA-K2anticoagulant artery blood samples were detected by XT-1800iblood cell analyzer.The samples with lithium heparin anticoagulation were detected by OMIN-C blood gas analyzer.Results The blood cell analyzer showed better precision and all results were in the permissible error range of CLIA＇88.The two indexes detected by blood cell analyzer were lower than those detected by OMIN-C blood gas analyzer,and showed significant difference（P0.01）.Conclusion The measurements of hematocrit with blood gas analyzer are significantly different from conventional method.It is very necessary to establish the reference intervals of hematocrit and hemoglobin for the blood gas analyzer.
