CLSI H62 Abstract

Clinical and Laboratory Standards Institute guideline H62–Validation of Assays Performed by Flow Cytometry focuses primarily on analytical method validation. There are currently no official guidance documents for the validation of assays performed by flow cytometry. Existing guidance for the validation of biochemical methods for quantifying soluble analytes found in plasma, serum, and urine is not fully applicable for quantification and characterization of cellular measurands. Validation of flow cytometry is challenging because the data generated are not derived from a calibration curve and true reference standards are lacking. Additional topics covered in this guideline include instrument qualification and standardization and assay optimization. It also covers recommended practices for the examination and postexamination phases. The recommendations presented in H62 are applicable to a wide range of flow cytometry laboratories, including basic research facilities, biopharmaceutical companies, medical laboratories, and manufacturers. This guideline provides specific recommendations for the appropriate analytical method validation approach based on the intended use of the data and regulatory and accreditation requirements, if any, associated with this use. H62 is designed to assist any laboratory using flow cytometry, as well as manufacturers, in developing, validating, verifying, controlling, analyzing, and implementing fluorescence cell-based assays.
