镁测定对二氧化碳结合力测定的影响

The Effect of Magnesium Determination on CO_2-CP

目的:镁测定试剂对二氧化碳结合力测定结果的影响分析。方法:所用仪器为美国贝克曼CX9型全自动生化分析仪,试剂为跟机原装进口试剂,严格按操作规程测定。结果:CX4部分按排顺序为Ca2+,Mg2+,CO2-CP进行检测时,全套生化检测病人标本的CO2-CP结果值降低。调整测定项目顺序为Mg2+,Ca2+,CO2-CP进行检测时,与抽样到CX3部分pH电极进行比对,结果相差很小。结论:镁测定试剂对二氧化碳结合力测定存在影响。

Objective： To analyze the influence of the magnesium determination reagent upon the results of the CO 2-CP.Method： the instrument is Beckman CX9 type fully automatic biochemistry analyzer,the reagents are the original import reagents matched with the machine,the determination is operated strictly according to the operation procedures.Results： Using CX4 part,the results of CO 2-CP reduced,when it was detected in the de-termination order of Ca 2＋,Mg 2＋,CO 2-CP.Adjust the determination order,in the order of Mg 2＋,Ca 2＋,CO 2-CP,the results of CO 2-CP had little difference with the samples which were detected by pH electrode in the CX3 part.Conclusion： the magnesium determination reagent has influence upon the determination of CO 2-CP.
