CD79a Flow Cytometry is a laboratory test that detects and measures CD79a, a protein associated with B lymphocytes and their development. Using flow cytometry, it helps identify and characterize B-cell populations in blood, bone marrow, or tissue samples. The test is needed to establish B-cell lineage and support the diagnosis and classification of B-cell leukemias, lymphomas, and other lymphoproliferative disorders by evaluating abnormal cellular marker patterns.
It may be useful when evaluating B-cell acute lymphoblastic leukemia, B-cell lymphomas, chronic lymphocytic leukemia, and other disorders involving abnormal B-cell populations.
No. CD79a is one marker within an immunophenotyping panel. Diagnosis requires correlation with other markers, blood or bone marrow findings, clinical information, and sometimes genetic or molecular testing.
CD79a-positive means that the evaluated cells express CD79a. This finding can support B-cell lineage, but its significance depends on the complete immunophenotyping profile.
CD79a-negative means that significant CD79a expression was not detected in the evaluated cell population. The result should be interpreted alongside other B-cell and lineage markers.
Yes. CD79a can help establish B-cell lineage in suspected leukemia. Additional markers are needed to determine the specific type and characteristics of the leukemia.
