Frequently Asked Questions
What does CD23 flow cytometry test measure?
CD23 is a surface marker expressed on B-cells. In flow cytometry, it helps differentiate Chronic Lymphocytic Leukemia (CLL), which is typically CD23-positive, from other B-cell lymphomas like Mantle Cell Lymphoma, which is usually CD23-negative.
Is fasting required for this test?
No, fasting is not required. The test is performed on whole blood and is not affected by food intake.
How is the sample collected?
A venous blood sample is drawn into an EDTA (purple top) or Heparin (green top) tube. A bone marrow aspirate may also be used in certain cases.
What does a CD23-positive result mean?
CD23 positivity on B-lymphocytes is a hallmark of CLL/SLL and helps confirm the diagnosis when combined with other markers like CD5, weak CD20, and light chain restriction.
How long does it take to get results?
Reports are typically available within 2–3 working days. Verified PDF reports can be accessed via www.drpatholab.in or WhatsApp/Email.
Can medications affect CD23 results?
Immunosuppressive drugs, recent chemotherapy, or blood transfusions may alter immune cell profiles. Inform your doctor about all current medications and recent treatments before testing.
