摘　　要：目的分析比对直接电位法、间接电位法和干化学直接电位法血清钾钠的测定结果,探讨仪器校准和比对在电化学分析中的作用。方法用配套检测系统校准强生Vitros250、罗氏AVL9180、常光EX-Z和日立7600-020生化分析仪并进行精密度试验、回收试验、线性试验和对比试验,对试验结果进行统计学分析。结果校准后各仪器间分析结果具有良好的可比性和相关性,差异没有显著性意义。结论日常工作中应当重视分析仪器的校准和不同仪器之间结果的比对工作,确保检验结果的准确性和一致性。Objective Comparison of the results of potassium ＆ sodium determining in mixed serum by direct potentiometric method,indirect potentiornetric method and dry chemistry direct potentiometric method. To explore the importance of calibration and comparison in electrochemistry analysis. Methods Calibrated Vitros 250,AVL 9180,EX-Z ＆ Hitachi 7600020 biochemistry analysators. Then evaluated the precision ,the recovery,the linearity and the contrast test. Finally, the results were analyzed with statistics. Results The results of the analysators showed the good comparability and correlation, statistical significance was less different obviously. Conclusion For showing good accuracy and consistency,the calibration and contrast test for analysators must be done well in routine work.
