Evaluation on the Identification and Counting of Nucleated Red Blood Cells by Sysmex XE-2100 Hematology Analyzer

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.
