摘要免疫细胞亚群检测在多种良恶性疾病的临床诊疗及健康管理中都起着非常重要的作用。为了更好地开展不同功能性免疫细胞亚群的深入研究和建立克隆性相关指标参考区间，建立免疫衰老、个体化动态监测和治疗恢复期特殊参考区间，发现淋巴细胞以外其他免疫细胞的临床意义等，迫切需要精细化分析外周血免疫细胞亚群。多参数流式细胞术是检测免疫细胞精细化亚群、进行免疫功能评价的重要技术方法，为规范外周血免疫细胞亚群的流式细胞术精细化检测方法和方案，进一步促进其在临床疾病诊疗和健康管理中的应用，中国中西医结合学会检验医学专业委员会组织专家制定了此专家共识。

abstractsThe detection of immune cell subsets plays a very important role in the clinical diagnosis and treatment of various benign and malignant diseases and health management. In order to better carry out in-depth research on different functional immune cell subsets, establish reference intervals for clonality related indicators, establish special reference intervals for immune aging, individualized dynamic monitoring and treatment recovery, and discover the clinical significance of immune cells other than lymphocytes, it is urgent to analyze the peripheral blood immune cell subsets in a refined way. Multiparameter flow cytometry is an important technical method to detect immune cell subsets and evaluate immune function. In order to standardize the refined detection methods and protocols of peripheral blood immune cell subsets by flow cytometry, and further promote its application in clinical diagnosis and treatment of diseases and health management, Laboratory Medicine Committee of Chinese Association of Integrative Medicine (LMC-CAIM) organized experts to formulate this expert consensus.
