Frequently Asked Questions
What does CD7 flow cytometry test measure?
CD7 is a cell surface glycoprotein expressed on all mature T lymphocytes and early myeloid precursor cells. Flow cytometry quantifies CD7-positive cells to assess T-cell lineage and detect abnormal immunophenotypes in lymphoid and myeloid disorders.
Is fasting required for this test?
No, fasting is not required. The test can be performed at any time during lab working hours.
Why is CD7 testing ordered?
CD7 flow cytometry helps diagnose and classify T-cell lymphomas, leukemias, and myeloid neoplasms. Loss or abnormal expression of CD7 is a hallmark of certain T-cell malignancies and helps differentiate reactive from clonal lymphoproliferative conditions.
What sample types are accepted?
EDTA whole blood or Heparin whole blood for peripheral blood samples. Bone Marrow Aspirate (BMA) is accepted for marrow-based evaluation.
How long does it take to get results?
Reports are typically available within 24–48 hours. Verified PDF reports can be accessed at www.drpatholab.in or via WhatsApp/Email.
Can medications affect CD7 results?
Immunosuppressive drugs or recent corticosteroid therapy may alter lymphocyte counts and CD7 expression patterns. Always inform your doctor about current medications before testing.
