Abstract:
Objective To design and verify an analytical method for the cross contamination of Beckman AU5800 automatic bio‐chemical analyzer′s reagent needle and stir bar .Methods The outer ring items (AST ,ALP ,TP ,LDH ,CK‐MB ,HBDH ,Urea ,UA , TG ,LDL‐C ,APOB ,Mg ,P ,Zn ,AMY ,CHE ,LPS ,ADA) were tested as the experiment objects .The cross contamination experiment was proceeded according to the test order .The impact rate range of 95% -105% was the criteria for cross contamination of items . Results Among all of the outer ring items ,TP ,HBDH ,APOB and TG were found to have cross contamination effect on CK‐MB , Mg ,Mg and LPS respectively .Conclusion The method established in this experiment can effectively analyze the cross contamina‐tion of all the items in Beckman AU5800 automatic biochemical analyzer .In addition ,it can help to adopt corresponding measures to reduce cross contamination and assure the accuracy of test results .
