Abstract:
Objective To perform the comparative analysis on the test results acquired from three different types of hematology analyzers ,to explore their results comparability or whether their deviations being within the allowable range .Methods The 30 d in‐ternal quality control results collected from the three types of analyzers ,Sysmex XE2100 ,Sysmex XN3000 and Sysmex XT4000i , were analyzed and analyze .The XE2100 hematology analyzer with excellent results in repeatedly participating in the national exter‐nal quality control assessment was taken as the reference instrument ,while the Sysmex XN3000 and Sysmex XT4000i analyzers served as the contrastive instruments .Four blood samples from different patients with high ,medium and low values were randomly selected and detected for 5 d .The results of white blood cell(WBC) ,red blood cell(RBC) ,hematocrit(HCT) ,hemoglobin(HGB) and platelet(PLT) were performed the comparative analysis .Then the accuracy and comparability of the detection results were judged by F test ,regression equation and correlation coefficient .Results The detection result of WBC ,RBC ,HCT ,HGB and PLT had no statistical differences among three instruments (P> 0 .05) .The correlation of various indexes had close correlation (r≥0 .975) .The deviations conformed to the related requirements with comparability .Conclusion When conducting detection by multi‐ple instruments ,the quality control of experimental instrument should be paid attention to ,the different detection instruments should be conducted the calibration and comparison at regular intervals for ensuring the accuracy and consistency of detection re‐sults ,thus better serve clinic .
