维和二级医院自制血常规质控的应用

The application of home-made specimen in internal quality control of hematological tests in Level 2 hospital of peacekeeping force

目的尝试用日常血常规全血标本代替商品化血常规质控,用于维和二级医院血细胞分析日常室内质量控制。方法从日常标本中挑选中、高值质控各一,定义为自制质控。和商品化质控同时进行室内质控分析,挑选白细胞(WBC)等6项质控项目分析自制血常规标本的稳定性。结果在对自制血常规质控连续测量20 d后,6项质控项目中WBC、血小板(PLT)、红细胞压积(HCT)、平均红细胞体积(MCV)在不同的天数出现稳定性降低的现象,尤其是PLT在第12天时,其变异系数CV就分别增高到8.56%和8.13%。但是仍然可以截取较短的时间用于室内质控。结论在选择10 d为1个周期的前提下,可以采用日常血常规标本作为血细胞分析的室内质量控制,从而解决维和二级医院血常规室内质量控制难以展开的困境。

Objective To use whole blood routine specimens to replace commercial blood routine control specimens in the internal quality control of hematological tests in Level 2 hospital of peacekeeping force.Methods Each medium and high value specimens were chosen from routine patient specimens and were designated as the home-made specimens,which underwent internal quality control analysis together with the commercial quality control specimens.Leukocyte and other five quality control blood components were chosen to analyze the stability of the home-made specimens.Results After 20 days of continuous detection of the home-made specimens,the stability of WBC,PLT,HCT and MCV in the 6 quality control specimens decreased at different day time points.Especially,at day 12,the coefficient of variation(CV)of PLT increased to 8.56%and 8.13%.However,it was still possible to take a short time for internal quality control.Conclusion On the premise of taking 10 days as a cycle,routine blood specimens could be used for internal quality control of hematological tests,thus solving the problem of the incapacity of Level 2 field hospital of peacekeeping force in internal blood routine quality control.
