Abstract:
Objective To explore the method of comparing different hematology analyzer in Sports Biochemistry Laboratories with the median concentration.Methods In accordance with the American Society of Clinical and Laboratory Standards Institute EP9-A2 document requirements,ADVIA120(120) was chosen as a standard comparative instrument,ADVIA2120i(2120) as a test instrument,six different batches of normal and non-normal 2 quality control were monitored continuously for one year,combined with 42 cases of fresh sample which were selected randomly,the author analyzed the precision,accuracy and comparability of the two instruments,and white blood cell(WBC),red blood cell (RBC),hemoglobin(HGB),hematocrit (HCT),mean corpuscular volume(MCV),mean corpuscular hemoglobin(MCH),mean corpuscular hemoglobin concentration(MCHC) and platelet(PLT) were chosen as the test indicators.Results The precision(CV％ values within a range of 0.9-5.0) of the two instruments were all within the CLIA'88 1/4 tolerance accepted range;All indicators' percentage difference between the two instruments are fit with the International Blood Standardization Committee(ICSH) Standard.The test results of 42 blood samples detected by different hematological analyzers were analyzed by regression analysis,which showed that the correlative coefficient (r) was over 0.97.Conclusion The method of continuously monitored the normal and non-normal 2 quality control for one year,combined with 42 cases of fresh sample which were selected randomly can well be used in the study of tests results comparability and consistency of two different hematological analyzers in Sports Biochemistry Laboratories.
