ABSTRACT
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.
