流式细胞学(flow cytometry,FCM)免疫分型是利用流式细胞仪对细胞表面或胞内抗原的表达状况进行检测,从而对细胞的系列、分化程度、表型是否异常等进行分析判断的高通量、高敏感性检测技术,在血液肿瘤诊断、亚型分析以及微小残留病(minimal residual disease,MRD)检测等方面发挥越来越重要的作用。恶性淋巴瘤的诊断难度较大, Flow cytometry (FCM) immunophenotyping is the use of flow cytometry on the cell surface or intracellular antigen expression was detected, and thus the cell line, the degree of differentiation, the phenotype is abnormal analysis and judgment High-throughput, high-sensitivity detection techniques play an increasingly important role in hematological tumor diagnosis, subtype analysis, and minimal residual disease (MRD) detection. Malignant lymphoma diagnosis is more difficult,
