目的：分析血气分析仪与干化学仪测定血钾离子结果的可比性。方法以干化学检测系统为比较方法（X ），以血气分析仪检测系统为实验方法（Y ），对同一时间采集的IC U新生儿动脉血进行血钾离子检测，以医学决定水平浓度的系统误差小于或等于美国临床实验室修正法规CLIA′88允许总误差（TEa）的1/2为标准，判断结果的可比性。结果两种检测系统的血钾离子结果有直线相关关系（r＝0．976，P＜0．01），3个医学决定水平中，仅在3．0 mmol/L处时两种系统间的系统误差可被临床接受。结论血气分析仪检测的全血钾离子浓度低于干化学仪测定的血清钾离子浓度，应以干化学仪检测结果作为诊疗依据，而血气分析仪结果仅供参考。

Objective To analyze the comparability of potassium results detected by blood-gas analyzer and dry chemical analy-zer .Methods Dry chemical detection system was used as comparison method (X) ,and blood gas analyzer systems was used as the experimental method (Y ) .Arterial blood samples collected from ICU newborns were detected respectively by the two methods .If SE of medical decision level was less than or equal to 1/2 TEa decided by CLIA′88 ,the results was acceptable .Results There was a linear correlation in potassium concentrations of the two detection systems(r=0 .976 ,P<0 .01) .But among three medical decision levels ,the SE of the two detection systems only acceptable at 3 .0 mmol/L .Conclusion The potassium concentration of blood gas analyzer is lower than that of dry chemistry analyzer .The potassium concentration of dry chemistry analyzer should be taken as a reference to diagnose and clinical treatment .
