Abstract: Objective　According to an organized survey，to analyze the determination quality of blood routine items among hospitals inferior to Grade 2 Level B. Methods　　The stabilized fresh blood samples with 2 lot numbers were used as the survey materials to investigate the performance of hematology analyzers from 257 medical institutions. The items included white blood cell (WBC)，red blood cell (RBC)，hemoglobin (HGB)，hematocrit (HCT) and platelet (PLT). Meanwhile，the blood smears from patient samples were used to check the ability for WBC differentiation and abnormal cell morphology identification. Results　The 4.7% hematology analyzers failed to pass. There were 1.9% of hospitals not having hematology analyzers. The 25% hospitals can pass the blood smear examination. Conclusions　Since there are still some problems in the hospitals inferior to Grade 2 Level B with respect to blood routine items，it is necessary and urgent to improve their laboratory practice，particularly blood smear identification.
