Objective To study the influence of blood routine test result by reverse mixing the intravenous anticoagulant blood samples for different times.Methods We selected EDTA-K2-anticoagulant blood samples from 46 cases of healthy subjects,then the samples were reversely mixed 3 times,6 times,9 times,12 times separately.Then we used MEK-6318K-automatic blood cell analyzer for whole blood analysis.Results There were significant differences of the percentage of median cells(MXD),platelet count(PLT),platelet distribution width(PDW),mean platelet volume(MPW) between the samples that were reversely mixed more than 9 times and 3 times.Conclusion To ensure the accuracy of blood routine test result,the intravenous anticoagulant blood samples must be reversely mixed for 3-6 times.
