Flow cytometry. From research to clinical laboratory applications

Flow cytometry has become a widely adopted analytical tool in clinical diagnostics. Prior research has shown that it enables rapid and precise analysis of cell populations in heterogeneous samples. In hematology, it has been used for leukocyte phenotyping and immune cell enumeration. However, the full potential of flow cytometry in characterizing non-leukocyte cell types remains underexplored. This gap motivated researchers to examine how flow cytometry could expand into new clinical areas. No prior work had resolved the extent of clinical utility for erythroid and granulocyte phenotyping. That uncertainty drove this review to assess current and emerging applications. The goal is to clarify how flow cytometry can support more diagnostic and prognostic decisions. This paper focuses on the transition from research to clinical use in specific cell types.

This review aims to evaluate how flow cytometry is being adopted in clinical settings beyond traditional leukocyte analysis. The specific problem is the limited understanding of flow cytometry's utility in non-leukocyte cell types. The motivation is to identify new diagnostic opportunities in hematology. The authors seek to highlight how flow cytometry can improve the characterization of erythroid and granulocyte populations. They also aim to assess the potential for functional analysis of these cells in clinical contexts. The focus is on how flow cytometry can provide diagnostic and prognostic insights. The study does not propose new methodologies but synthesizes existing clinical applications. The goal is to guide future clinical adoption of this technology.

The authors conducted a literature review of clinical applications of flow cytometry. They focused on hematology and immunology studies published in peer-reviewed journals. The approach involved categorizing applications by cell type and clinical use. They analyzed how flow cytometry is used for leukocyte phenotyping and immune cell counting. The review also included studies on erythroid cells and granulocytes. The authors evaluated the clinical relevance of these findings. They synthesized evidence from multiple sources to identify trends. The methodology emphasizes summarizing current clinical practices and potential future directions.

Flow cytometry is widely used in diagnosing leukemias and lymphomas through leukocyte phenotyping. It is also used to count peripheral blood lymphocytes in immune disorders. The review found that erythroid cells, including reticulocytes, are increasingly being studied with flow cytometry. Platelets and megakaryocytes are also being analyzed for clinical utility. Monocytes and granulocytes are being characterized for functional roles in disease processes. These applications suggest potential for improved diagnostic accuracy. The findings indicate that flow cytometry can provide prognostic information. The strongest evidence supports its role in immune disorder diagnostics.

The authors suggest that flow cytometry is expanding beyond traditional leukocyte analysis. They propose that erythroid and granulocyte phenotyping may offer new clinical insights. The review supports the idea that flow cytometry can improve diagnostic and prognostic assessments. The authors suggest that functional characterization of hematopoietic cells is a promising area. They propose that further clinical validation is needed for emerging applications. The synthesis indicates that flow cytometry has untapped potential in hematology. The authors suggest that broader adoption could enhance diagnostic capabilities. They conclude that flow cytometry is a valuable tool in both research and clinical settings.
