ABSTRACT
Objective To investigate the application of lymphocyte parameters in screening the lymphocyte proliferation and re-active hyperplasia disease.Methods 128 cases as the healthy control,100 cases of lymphoma,35 cases of multiple myeloma(MM), 34 cases of lymphocytes reactive hyperplasia(RL)and 5 cases of chronic lymphocytic leukemia(CLL)were selected and performed the peripheral blood cells analysis by the Sysmex XE-2100 hematology analyzer.The relevant lymphocyte parameter values were re-corded and the comparative analysis in the difference between the disease groups and the control group was performed.The role of each lymphocyte parameter in screening the lymphocyte proliferation and reactive hyperplasia diseases was evaluated by the receiver operating characteristic curve(ROC curve).Results The high fluorescence lymphocytes(HFL),in the control group was 0.008 ± 0.008,in the lymphoma group was 0.016±0.058,in the MM group was 0.019 ±0.063,in the RL group was 0.040 ±0.070,and CLL group was 0.388±0.158.Compared with control group,the difference of RL and CLL group was statistically significant(P morphological changes of lymphocytes sensitively and contribute to screening the patients with lymphocyte proliferation and reactive hyperplasia disease.
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.
