患者血清总胆红素测定均值在质量控制中的应用

目的通过对该院测定的患者和健康体检人员血清总胆红素结果分析，建立用患者结果均值法做室内质控的方法，并对参考区间进行了验证。方法运用SPSS13．0软件统计包的Frequencies对整个数据类型进行分析，然后根据数据出现频率确定分析区间，计算分析区间内每天数据均值，将每天均值作为一个测定数据，按运用质控品进行质控的方法进行质控。每月月底对不同仪器的均值进行比较，作为仪器间比对的一种方法。根据健康体检人员结果，按公式均值±1．96s对现行参考区间进行验证。结果每天均值作为质控数据进行质控其变异系数在可接收范围，健康体检人员数据95％分布区间与现行参考区间相同。结论制定适当区间，区间内数据平均值进行室内质控有意义；本院现行参考区间合理。

Application of serum total bilirubin mean in quality control

Objective To analyze the levels of serum total bilirubin in patients and healthy con-trols, eatablish a method of using the mean of total bilirubin in serum of patients to control internal quality, and validate the reference range. Methods Frequencies mode of SPSS13.0 statistic software package was applied to performing analysis of all data, and then the analytic interval was determined based on the frequencies of the data. The daily data mean in the analytic interval was calculated. With the daily data mean as the testing data, the quality control was carried out by the same way of quality control for quality control sample. At the end of each month, the means of various analyzers were compared. Based on the results of healthy controls, the formula mean±1.96s was used to validate the current reference range. Results With the daily data mean as the testing data for quality control, its coefficient variation was within the accepatable limit, and the 95% distribition range was the same as the current reference interval. Conclusion It is necessary to establish suitable interval in which the da-ta mean was used for internal quality control. The current reference range in our hospital is proper.
