Objective To investigate accuracy of the full automatic blood analyzer for the low platelets.Methods The result of platelets in 102 patients with the blood cell analyzer and reference method and counting by microscopy,explore the sensitivity of the blood cell analyzer in low PLT with ROC Curve.Results FOR the blood analyzer,102 patients′ ROC Curve of Area was 0.893.Area was 0.846 if platelets were between 30×109/L-50×109/L,Area was 0.746,if platelet were 10×109/L-30×109/L.Area was 0.650,if platelet were 0×109/L-10×109/L.For the hand counting,102 patients′ Area was 0.759.Area was 0.702 if platelets were between 30×109/L-50×109/L,Area was 0.780 if platelets were between 10×109/L-30×109/L,Area was 0.565 if platelets were between 0×109/L-10×109/L.Conclusions For all the cases,the automatic blood cell analyzer′s accuracy was good,but when PLT was felled more and more,analyzer′s accuracy decreased.The platelet was 10×109/L by the blood cell analyzer,it should be reviewed,but at that time,the hand counting couldn′t make a good help.It should be tested by FCM.
