ABSTRACT
Objective To evaluate the identification and counting effeciency of nucleated red blood cells by Sysmex XE-2100 Hematology Analyzer. Methods Accurancy: nucleated red blood cells were counted from 38 specimens by Sysmex XE-2100 Hematology Analyzer and compared with the number counted under microscopy. Precision: 3 specimens with different values were counted for the nucleated red blood cells 10 times by Sysmex XE-2100 Hematology Analyzer and compared with the number counted under microscopy. The CV(% ) value was estimated.Results There was insignificant difference between the results obtained from Sysmex XE-2100 Hematology Analyzer and those under microscopy. In the T-test, P >0.05, r=0.9893(P< 0.01).CV(% ) were 8.1% and 15.8% . It means that the Sysmex XE-2100 is more precise in analyzing the nucleated red blood cells than that under microscopy. Conclusion The nucleated red blood cells count by Sysmex XE-2100 is accurate and fast to obtain clinical data.
