Objective To discuss the reason of blood platelet(PLT)examination result somewhat low in XT-1800i blood analyzer application,choose the correct method to carry on the reexamination and guarantee the PLT examination quality.Methods Five hundred and thirty-two specimens of PLT examination result somewhat low in XT-1800i blood analyzer application were reexamined with manual method,and simultaneously made the circumference blood smear microscopic exam to observe blood platelet shape.Results The results of 219 specimens were still somewhat low and there were not difference between before and after the reexamination(P 0.05).The blood smear blood platelet showed uniform distribution and the shape was approximately normal;The results of 313 specimens reexamination showed the platelet count was normal,on 306 specimens blood smears appeared the giant blood platelet,on 7 specimens blood smears the blood platelet had the varying degree the accumulation.Conclusion The examination blood platelet result somewhat low specimen in blood analyzer application should be carried on the peripheral blood film with microscopy and the manual counting blood platelet.
