Objective To discuss the setting method and following measures of the automatic biochemical analyzer to execute quality control. Methods The initial setting value of the absorbance limit was determined by selecting the automatic biochemical analyzer with the concentration close to the upper limit, then dilution factor and retest conditions were set based on reaction types. Results The setting of absorbance limit setting ensured the accuracy, reliability, quality and efficiency of the automatic biochemical analyzer while lowered the cost. Conclusion Setting correctly the absorbance limit contributes to the accuracy of the biochemical analyzer when combined with laboratory information system, automatic or manual dilution retest as well as laboratory automation system.
