Abstract:
Objective To establish a network laboratory for blood cell analysis and better calibrate haematology analyzers in local lab.Methods According to GB/T 15481《General requirements for the competence testing and calibration laboratories》(idt ISO/IEC 17025),we established a network laboratory providing traceability for blood cell analysis.Complete blood count was traced to Calibration Laboratory in NCCL;The secondary standard haematology analyzer with the same model and calibrator with same lot number were used for verification for a long period.Fresh blood from healthy people was used to calibrate haematology analyzers.Results Gradually we have improved our laboratory quality management system, precision as well as accuracy,which was satisfactory.The unified blood sample was adopted to calibrate different equipments in our hospital and showed consistence when compared with calibration analyzer.The correlation coefficient of all tests is more than 0.99.The relative deviation of WBC,RBC,HCT,HGB and PLT are within?7%,?3.5%,?4%,?3% and?15%,respectively.Conclusions Secondary standard systems provides good comparable results with calibration laboratory.Its tracing mode and quality control scheme could ensure the traceability and accuracy of completed blood count.Furthermore,using elective fresh blood from healthy people,the comparable results from different analyzers were achievable.
