Evaluation of CELL-DYN1700 automated hematologic analyser in clinical application

Objective: To evaluate the function of the CELL DYN1700 automated hematologic analyser in clinical application.Methods: The accuracy,precision,contamination carrying rate and linearity range were measured using clinical samples.Results: The CV with in the group were as follows:white blood cell(WBC) 1.9%,red blood cell(RBC) 1.65%,hemoglobin(Hb) 1.35%,hematocrit(HCT) 2.0%,mean corpuscular volume(MCV) 0.93% and blood platelet counts(BPC) 3.2%.The CV between the groups were as follows: in the high blood value group,WBC 2.7%,RBC 2.21%,Hb 1.86%,HCT 2.8%,MCV 1.9% and BPC 6.0%;in the normal blood value group,WBC 2.1%,RBC 1.9%,Hb 1.7%,HCT 2.3%,MCV1.8% and BPC 3.6%;in the low blood value group,WBC 2.0%,RBC 2.1%,Hb 1.68%,HCT 2.4%,MCV 1.92% and BPC 6.8%.The lineariyt range was wide:WBC(0.5 to 90.0)×10⁹/L,RBC(1.0 to 7.0)×10¹²/L,Hb(25.0 to 200.0)g/L、BPC(10.0 to 999.0)×10⁹/L.The contaimination carrying rate was low:WBC 0.1%,RBC 0%,Hb 0%,BPC 0.5%.The accuracy of this analyzer was high.The results showed no significant difference between the EDTA-K₂ anti freezing vessl blood analyser and conventional detection.Conclusions: This analyzer has the advantages of high accuracy,high repeatability,easy operation,fast detection and little cross pollution.It can test 18 pharaments with vessl blood or finger blood.
