RESUMO
Objective To study the role of hematology analyzer in the preliminary diagnosis of hematological malignancies. Methods The blood routine results of 121 patients with initial hematological malignancies in the Second Hospital of Shanxi Medical University from October 2016 to February 2017 were analyzed by differential blood count (DIFF) scatter chart and alarm information of hematology analyzer SYSMEX XE-2100. Results Among 121 patients with hematological malignancies, 96 cases (79.3 %) had abnormality of DIFF scatter chart. The DIFF scatter chart of acute lymphoblastic leukemia, chronic lymphocytic leukemia, acute promyelocytic leukemia, and chronic myeloid leukemia had their own distinct characteristics, but the features of other types were not obvious. According to blood smear, blood cells analysis alarmed that the coincidence rates of primitive cells, immature granulocytes, nucleated erythroblasts and atypical lymphocytes were 87.7 % (50/57), 76.3 % (42/55), 33.3 % (19/57), 43.1 % (31/72) respectively. Conclusion The DIFF scatter chart of hematology analyzer and alarm information play very important roles in the diagnosis of hematological malignancies.
