Objective To discuss the effectiveness and possibility of applying Grubbs extreme value to inspeet the clinical and chemical unfixed value quality control RCV.Methods To use Grubbs method to do the total gradual inspection of unfixed value blood serum RCV and leave out the exceeding value in time and measure it supplementally in the same day.To use the evaluating blood serum to improved Monica method to do the random inspection of accuracy.Results In 20 days’measure,We find Cr and BUN totally exceeding three times.If ±3s method is used,there is no exceeding value.Comparing the two methods,Cr and BUN’s CV % is reduced to 7 81 and 5 94 from 10 10 and 8 09.The sample error which can not be reflected under parallel inspection is found by analyzing.Conclusion The immediate feature is quite obvious when inspecting RCV by using.Grubbs method.It helps to enforce the internal quality control.This method is convenient and effective.
