Frequently Asked Questions
What does CD45 flow cytometry test measure?
CD45 is a pan-leukocyte marker expressed on all nucleated blood cells. It helps identify and gate white blood cell populations during flow cytometry analysis for diagnosing blood cancers and immune disorders.
Is fasting required for CD45 flow cytometry?
No, fasting is not required. The test can be performed at any time during lab working hours.
What sample is used for this test?
EDTA whole blood or Heparinized whole blood is collected. Bone marrow aspirate (BMA) may also be used when evaluating marrow-based conditions.
Why is CD45 important in leukemia diagnosis?
CD45 helps distinguish leukemic blasts from non-hematopoietic cells and is used to identify abnormal immunophenotypes in acute leukemias and lymphoproliferative disorders.
How long does it take to get results?
Reports are typically available within 24-48 hours. Verified PDF can be accessed via www.drpatholab.in or WhatsApp/Email.
Can medications affect CD45 flow cytometry results?
Immunosuppressive drugs or recent blood transfusions may alter leukocyte marker expression. Inform your doctor about all current medications before testing.
