MIFlowCyt: Can Another Analyst Reconstruct Your Flow Experiment?

The missing detail is often outside the final plot

A percentage can look precise while leaving its origin unclear. Which specimen was processed, what did the reagent measure under those conditions, and which events form the denominator? A reporting audit should connect these questions before treating a result as reconstructable.

What the 2008 standard contributes

Lee and colleagues' MIFlowCyt paper in Cytometry Part A organises minimum reporting information around the experiment overview, samples, instrument and data analysis. It asks for the purpose, preparation and relevant configuration, together with access to list-mode data, compensation details and an unambiguous gating description. The hierarchy should be traceable back to all events, and percentage denominators should be stated.

The article distinguishes required and recommended reporting information. It describes information content rather than prescribing one storage format. This is historical reporting guidance, not a new 2026 clinical validation study.

A practical reconstruction exercise

Choose a completed experiment and give a colleague the report plus its referenced records. Ask them to identify the acquisition file, specimen treatment, reagent identity, relevant instrument settings, compensation and the population used as denominator. Let them record missing or ambiguous links rather than resolve them by asking the original operator.

Keep the exercise small enough to finish. A useful first outcome is a list of questions that the saved evidence cannot answer. For example, the colleague may find a gate name but no account of its parent population, or an acquisition file with no reliable link to the treatment record. These are proposed audit scenarios, not observations from the MIFlowCyt publication.

Documentation and performance answer different questions

Complete records make the measurement easier to inspect; they do not prove that its analytical performance meets an intended clinical use. A perfectly documented unsuitable threshold remains unsuitable. Record the evidence needed for interpretation separately from the studies that support detection, quantification or classification.

Use the reconstruction findings to repair the record system and then repeat the exercise on another experiment. Avoid declaring a whole laboratory compliant from one convenient example. Preserve the date and scope of the check so a later reviewer can tell which version was examined.

A reproducibility checklist is useful when it exposes a missing link. It is not a substitute for assay validation.
