血气分析仪与其他仪器部分相同检测项目的比较分析

Comparative analysis on the test result of some of the same test items by blood gas analyzers and other instruments

目的探讨血气分析仪与电解质分析仪以及生化分析仪在不同类别的样本中血钾(K+)、血钠(Na+)、血糖(Glu)检测项目的可比性。方法分别用GEM Premier 3000血气分析仪与镇江奥迪康电解质析仪及迈瑞生化分析仪对30例患者的动脉全血和静脉血清样本进行K+、Na+、Glu的检测,对检测结果进行相关分析。结果血气分析仪和生化分析仪测定Glu的结果以及血气分析仪和电解质分析仪测定Na+的结果,二者的差异均无统计学意义(P>0.05)。血气分析仪测定K+的结果显著低于镇江奥迪康电解质析仪的测定结果,差异有统计学意义(P<0.05)。结论 GEM Premier 3000血气分析仪能替代传统电解质分析仪和生化分析仪测定K+、Na+、Glu,其中K+的结果有差异但存在正相关。

Objective To study the comparebility of the blood gas analyzer,electrolyte analyzer,and biochemical analyzer in testing different samples of potassium（K＋）,the serum sodium（Na＋）,blood glucose（Glu）.Methods The results of K＋,Na＋,Glu of arterial whole blood and venous serum samples in 30 patients were tested by GEM Premier 3000 blood gas analyzer,Zhenjian Oticon electrolyte analyzer and Mindray biochemistry analyer,then the correlation analysis was performed.Results The level of Glue tested by blood gas analyzer and biochemistry analyzer,were not significant different（P〈0.05）,The K＋ level tested by blood gas analyzer was lower than that tested by electrolyte analyzer,with significant difference（P〈0.05）.Conclusion The results of the GEM Premier 3000 blood gas analyzer can replace the traditional electrolyte analyzer and biochemical measure for detecting K＋,Na＋,Glu,althongh the result of serum K＋ level was different,there is a positive correlation.
