Flow Cytometry Method Validation Protocols
Bibliographic record
Abstract
Analytical method validation provides a means to ensure that data are credible and reproducible. This unit will provide a brief introduction to analytical method validation as applied to cellular analysis by flow cytometry. In addition, the unit will provide practical procedures for three different types of validation. The first is a limited validation protocol that is applicable for research settings and non-regulated laboratories. The second is validation protocol that presents the minimum validation requirements in regulated laboratories. The third is a transfer validation protocol to be used when methods are transferred between laboratories. The recommendations presented in this unit are consistent with the white papers published by the American Association of Pharmaceutical Scientists and the International Clinical Cytometry Society, as well as with Clinical Laboratory Standards Institute Guideline H62: Validation of Assays Performed by Flow Cytometry (currently in preparation). © 2018 by John Wiley & Sons, Inc.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
