Calibration of the AU2700/Zhongsheng reagent system using Beckman calibrator transmitted by the testing system

Objective To study the feasibility of using Beckman calibrators to cabibrate the Olympus AU2700/Zhongsheng reagent system. Methods From the testing system that was composed of Roche reagent,Roche cfas and Hitachi 7060 automatic biochemical analyzer,the quality was transmitted to the fresh mixed patient sera. The indicative value of the Beckman calibrator was transferred into the actual value on the Olympus AU2700/Zhongsheng system. Urea,Creatimine(Cr),glucose(Glu),calcium(Ca),magnesium(Mg),uric acid(UA),triglyceride(TG),cholesterol(CHOL) in 40 fresh sera were measured by the standard system and the Olympus AU2700/Zhongsheng system which was calibrated by the indicative value and the actual value of the Beckman calibrator respectively. All results were analyzed by SPSS 11.0 software. Results Compared with the indicative value,the relative bias of Urea,Cr,Ca,TG were above 5%. Meanwhile by analyzing data of 40 fresh sera, the results of the Olympus AU2700/Zhongsheng reagent system that was calibrated by the actual value of the Beckman calibrator were consistent with the standard system. Conclusions When the Beckman calibrator transmitted by the standard system is using to calibrate the Olympus AU2700/Zhongsheng reagent system,the results between the Olympus AU2700/Zhongsheng reagent system and the standard system are comparable.
