Analysis of three blood collection models of hematology analyzer

Objective:To investigate the difference of three blood collection models that are determined by automatic hematology analyzer. Methods:Venous blood,peripheral blood from finger was treated with anticoagulant (EDTA-K2) to prevent clotting of blood; meanwhile,peripheral blood from finger was diluted by dilute liquid (1 ∶26). The blood samples were analyzed with whole blood model and dilute model respectively. Results:White blood cell (WBC),red blood cell (RBC),hemoglobin(HCG) and hematocrit (HCT) in three models showed no significant difference,but platelet count (PLT) showed significant difference between the peripheral blood of diluted and anticoagulant venous blood or anticoagulant peripheral blood. Conclusion:Under a certain condition,it is feasible that anticoagulant peripheral blood replaces anticoagulant venous blood,the results of peripheral blood been diluted are unsteady,and it is not suggested to put into use.
