The performance evaluation of reticulocytes detected by XN-3000 automatic blood analyzer / 中国医学装备

ABSTRACT

Objective:To evaluate the performance of reticulocyte (Ret) detected by Sysmex XN-3000 automatic blood analyzer.Methods: 96 blood samples were collected randomly in clinical detection of reticulocytes, and respectively were detected by XN-3000 automatic blood analyzer and microscopy. The precision, stability, linearity and carryover of Ret in blood samples detected by XN-3000 automatic blood analyzer were evaluated by the correlation analysis of the results from the two methods and the correlation analysis would be completed by microscopy.Results: precision, linear range and sensitivity of Ret measured by XN-3000 were within the allowable range. The stability did not change significantly below 4℃ within 48h (CV<1%). The carryover rate was 0.14%. The results measured by XN-3000 were well compared with microscopy (r=0.979).Conclusion: Sysmex XN-3000 automatic blood analyzer is applied to the clinical detection of large quantities of specimens and it is ideal for measuring Ret.
