CLIS质控管理软件在尿液干化学法室内质控中的应用

Application of Urine Dry Chemistry Method for CLIS Control Management Software in Internal Quality Control

目的应用CLIS质控管理软件进行尿干化学法室内质控。方法根据每个批次质控品的参考范围建立实验室的均值和标准差。质控品在Uritest-500型尿干化学分析仪进行尿11项测试，除尿液比重、pH外，其它定性测定项目结果定义为：0代表阴性，0．5代表±，1代表1＋，2代表2＋，3代表3＋，4代表4＋。定性数值以阳性数值均值的系数为均值，标准差根据阳性级别取1或0．5输入CLIS质控管理软件。任意一个试剂模块的测定结果与质控尿液期望“靶值”允许有一个等级的差异，超过此范围或结果在“正常和异常”之间跳跃均应视为失控。结果CLIS质控管理软件将尿液干化学定性结果数量化，可直观反映每日的室内质控结果。结论该方法操作简单，提高了检验科工作效率，有较强的实用性和可行性，是一个有效的质控图绘制方法。

Objective To apply CLIS quality control management software to carry on the urine dry chemistry method of internal quality control. Methods Established the lab reference range of mean and standard deviation according to each batch quality products. Quality products in Uritest-500 type tested urine 11 items of urine dry chemical analyzer. Except for the urine specific gravity, pH,other qualitative determination of project results were defined as 0 represents negative, 0.5 represents±, 1 represents 1＋2 represents 2＋ ,3 represents 3＋ and 4 represents 4＋. Qualitative with positive values was the coefficient of mean and standard deviation was input level 1, or 0.5 to CLIS quality management software according to the positive. Any measurement results and quality control of urine reagent module expectations,＂target value＂ was allowed for a level difference,more than the range,or the results between the normal and abnormal jump should be regarded as out of control. Results ELlS quality management software made urine dry chemical qualitative results quantification, and could intuitively reflect the daily internal quality control results. Conclusion The method is simple in operation and improve the efficiency of the clinical laboratory work, has the strongpracticality and feasibility of figure drawing method is an effective quality control.
