What should you know about imaging flow cytometry?

Cells in a fluid sample pass through the instrument one at a time. Light-based measurements can describe features such as size, internal complexity, and markers attached to the cell surface or inside it. At the same time, the system records an image of each cell. This adds visual context to measurements that standard flow cytometry may report as data patterns without an image for every event.

The sample may come from blood, bone marrow, or another tissue prepared by a laboratory. Specialists choose markers and analysis settings for the clinical question. The report is interpreted alongside symptoms, examination, blood results, pathology, and imaging; the test is one part of an assessment rather than a stand-alone answer.

Usually, the laboratory receives and prepares the sample rather than placing you inside a machine. Ask where the sample will come from, whether a procedure such as a bone marrow biopsy is needed, and how the sample should be handled. Tell the requesting team about medicines and recent treatments that may affect cell findings. Keep the appointment where a clinician explains the report and its next steps.

Imaging flow cytometry does not usually cause symptoms because analysis happens on a collected sample. If a collection procedure was performed, follow its wound-care instructions and report increasing pain, bleeding, redness, fever, or drainage. Seek urgent help for heavy bleeding, severe weakness, breathing difficulty, fainting, or rapidly worsening symptoms.

Ask what sample is being analysed, which cell markers are included, whether the test is replacing or supplementing another examination, when the report will be ready, and how the findings affect the next clinical decision.
