Judging the Changes of HITACHI Biochemical Analyzer Light Source Performance by the Instrument Quality-Control Value

This paper focuses on the changes of light source performance of Hitachi 7600 and 7180 biochemical analyzer.Through statistical comparison of quality control data of different test items,we found a testing material,apolipoprotein B,which has good sensitivity and consistent changes with performance of light source.We also compared apolipoprotein B with both ALT and apolipoprotein A,thus to prove its unique sensitivity.At the same time,we also recognized the relevance of quality control and calibration of testing equipment in some of the components(electrodes) performance changes.
