What should you know about nano flow cytometry?

Conventional [Flow Cytometry](/technology/flow-cytometry/) examines cells as they pass through a laser beam. Nano flow cytometry adapts the approach for particles smaller than typical cells, such as vesicles released by cells. The instrument records light scatter and fluorescent signals, helping a laboratory assess particle size, concentration, and selected markers.

This is a laboratory technique, not a scan or a diagnosis on its own. Results depend on the sample, preparation method, instrument settings, and markers selected. In cancer care, a specialist may use the findings alongside pathology, imaging, blood results, or a [Bone Marrow Biopsy](/treatments/diagnostics-and-staging/bone-marrow-biopsy/). A result needs interpretation in the context of your condition and the purpose of the test.

Ask which sample is needed, whether you need to change food or medicines, and when the result will be discussed. If blood is collected, tell staff about medicines that affect bleeding and any previous difficulty with blood tests. Keep the laboratory report with your other records, and ask which findings are confirmed, exploratory, or still being investigated. Do not change treatment from a laboratory result without speaking with the responsible clinician.

The test itself usually involves sample collection rather than a procedure on an organ. Seek help for persistent bleeding, increasing pain, swelling, redness, or fever after a blood draw or other sample procedure. If the sample came from a biopsy, follow the biopsy team's wound-care instructions and use its urgent contact number for heavy bleeding, worsening pain, or signs of infection.

What particles or markers is this test assessing? Which sample will be used? Is the method established for my clinical question, and what could affect the result? When will the findings be reviewed with my other test results?
