Abstract:
Objective To evaluate the performance of the CellaVisionTM DM96 analyzer during detection of intracellular para-sites of peripheral blood smears.Methods This study compared the detection rates of Plasmodium and Babesia species on peripheral blood smears utilizing the CellaVision DM9 6 with the rates for a routine red blood cell morphology scan.A total of 307 slides were analyzed,consisting of 142 slides positive for Plasmodium or Babesia species and 165 negative controls. Slides were blinded,randomized,and analyzed by CellaVision 9 6 and microscopy for red cell morphology scans.The technolo-gists were blinded to prior identification.Results The examination of common technician and blood professional technician, whether using optical microscope or CellaVision DM9 6 could accurately identify all the negative control,its specificity was 100%.The sensitivity of blood professionals using CellaVision DM96 was not statistically significant in the sensitivity of the laboratory and the use of light microscopy for the detection of Plasmodium parasites (χ2=0.24,0.03,0.43,P>0.05).The higher percentage of Plasmodium in blood smear,the higher detection rate of CellaVision DM9 6 .When the blood smear Plas-modium white rate greater than 1%,only 2 contain Plasmodium falciparum samples were negative for the miscarriage of j us-tice.The blood smear percentage was higher than 2% CellaVision of Plasmodium DM96 will all the blood smear 100% cor-rect interpretation.Conclusion This study demonstrates that CellaVision had the potential to detect intracellular parasites in routine screening of blood smears resource for storing images to be used for educational purposes,including training technol-ogists in the detection of intracellular parasites.
