Clinical Evaluation of Sysmex XE-5000 Hematology Analyzer

Objective To evaluate the major performance of Sysmex XE-5000 hematology analyzer. Methods Precision,carry-over rate,total reproducibility, leukocyte differential count reproducibility and linear range of Sysmex XE-5000 hematology analyzer were validated and we compared it with Sysmex XE-2100 hematology analyzer as well.Capillary blood and body fluid function were also evaluated. Results Compared with Sysmex XE-2100,the precision,total reproducibility and linear range of Sysmex XE-5000 hematology analyzer were better.Cross contamination rate of WBC,RBC,HGB,HCT and PLT examination were less than l%;There is no significant difference between capillary and venous blood count measurements using XE-5000.The capillary approach provides reliable blood counts.Cell count and differentiation of cerebrospinal fluid cells using XE-5000 showed good agreement between the automated and manual methods. Conclusion Sysmex XE-5000 hematology analyzer is ideal product for its exact and reliable performance.
