Summary

Immunophenotyping by flow cytometry plays a crucial role in many aspects of medical hematology and has replaced many traditional manual procedures. Many of these procedures are critical to clinical decisions in areas of hematopathology, infectious disease, and transplant medicine. Though more sensitive and accurate, there are many variables that can impact flow cytometry results and must be controlled in a comprehensive quality control and quality assurance program. These variables include: the collection, transportation, and sample handling to maintain optimum sample integrity; the instrument set-up and performance; the reagent performance (specifically monoclonal antibodies); and the acquisition and analysis of the generated data. This chapter will review the initial optimization and validation of clinical flow cytometry assays (both with respect to instrumentation and reagents). In addition, details will be provided for the monitoring and maintenance of the assay specifications (precision and accuracy) to ensure that high quality, reliable, and reproducible results are reported.
