Two types of blood cell analyzer and microscopic comparison of platelet count

Objective To study the two blood cell analyzer and microscopic comparision of platelet count.Methods Select the PLT 20×109/L,20-50×109/L,50-100×109/L,100-300×109/L,300×109/L retrospectively from the patients in 5 groups,among which 20 cases with PLT 20×109 /L and 300×109/L were made up as a group,and the other three groups were composed of 30 cases respectively,and microscopic platelet was conducted by means of Sysmex XT-2000i,MEK-6318K,and the result was regarded as a reference.Results When the PLT 20×109/L and 300×109/L,the comparison of MEK 6318K and microscopic with the platelet count has a significant difference(P0.01),Sysmex XT-2000i and microscopic platelet count were of no significant difference(P0.05);when PLT at 20-50×109/L,50-100×109/L,100-300×109/L,the difference among the three groups was not significant(P 0.05).Conclusion When the platelet is too small,too much,and when the blood cell analyzer prompted abnormal platelet distribution or abnormal platelet histogram,it is necessary to review the use of hand-counting method in time.
