Flow Cytometry Principles and Applications

This topic covers the fundamental principles and clinical applications of flow cytometry, a cornerstone technology in immunology and hematology at the tertiary level. Zambian university students in biomedical science and immunology programs will learn how flow cytometry analyzes the physical and chemical characteristics of cells or particles as they flow in a fluid stream past a laser. Key concepts include forward scatter (FSC) for cell size, side scatter (SSC) for cell granularity/internal complexity, and fluorescence detection for specific markers using conjugated antibodies. The topic also addresses critical technical adjustments like compensation to correct for spectral overlap between fluorescent dyes. For Zambian diploma and degree learners, proficiency in flow cytometry is essential for diagnosing hematological malignancies (e.g., leukemias), immunophenotyping, monitoring HIV progression via CD4 counts, and conducting advanced research. This knowledge is vital for passing practical and theoretical examinations and is a highly sought-after skill in clinical laboratories, research institutions, and public health programs across Zambia, directly impacting patient diagnosis and management.
