Quality control in clinical flow cytometry

Area of Science:

• Hematology
• Immunology
• Clinical Diagnostics

Background:

• Flow cytometry immunophenotyping is a complex technology for analyzing leukocytes.
• It is vital for characterizing normal lymphocyte subsets and hematologic neoplasms.
• Irreplaceable samples like bone marrow and fresh tissue are often used.

Purpose of the Study:

• To highlight the importance of flow cytometry immunophenotyping in hematologic diagnostics.
• To emphasize the critical role of sample handling and analysis in patient treatment decisions.
• To underscore the necessity of standardized procedures and quality control.

Main Methods:

• Enumeration and characterization of leukocytes using flow cytometry.
• Analysis of diverse biological samples including peripheral blood, bone marrow, and fresh tissue.
• Comprehensive review of preanalytic, analytic, and postanalytic processes.

Main Results:

• Accurate immunophenotyping yields critical diagnostic and prognostic information.
• Standardized protocols ensure reliable enumeration and characterization of cell populations.
• Quality assurance programs are essential for reproducible results.

Conclusions:

• Optimized and standardized flow cytometry immunophenotyping is essential for accurate patient diagnosis.
• Rigorous quality control across all process stages is critical for reliable results.
• This technology significantly impacts treatment decisions for hematologic conditions.
