What should you know about immuno flow cytometry?

Cells are mixed with antibodies carrying fluorescent tags. Each antibody attaches to a particular marker, if that marker is present. The sample passes through an instrument one cell at a time. Lasers detect the light from the tags, allowing a specialist to group cells by their features and compare normal-looking populations with unusual ones.

The result is interpreted with your symptoms, examination, blood counts, scans, and other pathology findings. It may help classify abnormal blood cells, support the assessment of a suspected blood disorder, or identify markers relevant to treatment. A result is not interpreted in isolation and does not by itself describe how you will feel.

The sample may be blood, bone marrow, or tissue. A blood sample usually involves a needle in a vein. If a bone marrow sample is needed, the team will explain the procedure, preparation, and local anaesthetic; you can read more about Bone Marrow Biopsy. Ask whether you need to change any medicines before sampling.

Bring details of recent medicines, infections, transfusions, and earlier test results when requested. Ask when the laboratory report is expected and whether additional testing may be needed. The Flow Cytometry technology page gives more detail about the method and its uses.

Follow the instructions given for the sampling site. Contact the clinical team if bleeding does not settle with firm pressure, redness spreads, swelling increases, or pain becomes more intense. After a bone marrow procedure, seek advice for fever, discharge, or worsening tenderness at the site.

Seek urgent care for heavy bleeding, severe weakness, fainting, or difficulty breathing. These symptoms are not expected from a routine sample and need prompt assessment.

Ask what sample will be tested, which cell markers are being examined, whether the test is diagnostic or part of treatment planning, and when results should be discussed. Ask how the findings will be combined with your blood count, tissue examination, or imaging.
