B lymphocyte cell surface markerspasting; Flow cytometry - leukemia/lymphoma immunophenotyping B-cell leukemia/lymphoma panel is a blood test that looks for certain proteins on the surface of white blood cells called B-lymphocytes. The Geisinger flow cytometry group recommends the following utilization guidelines for peripheral blood flow cytometry testing. Leukemia and lymphoma analysis by flow cytometry aids in identifying the tumor lineage, which in most cases is identified as T cell, B cell, or myeloid. In addition to reflexing flow cytometric panels, AML FISH testing for PML-RARA translocation t (15;17) may be added by the Mayo Clinic pathologist to exclude acute promyelocytic leukemia if there is morphologic suspicion or if blasts and promyelocytes are CD34-negative and HLA-DR-negative. B-cell leukemia/lymphoma panel. We provide a complete report, including a pdf of our analysis of the flow cytometric results. The cell count must be >100/μL for optimal analysis.

It is defined as a lymphoma of follicle center B-cells , which has at least a partially follicular pattern. Generally, a 2-10 mm section of fresh tissue is adequate. Immunophenotyping using multiparameter analysis (simultaneous staining with a pan B-cell marker and anti-immunoglobulin light chain antibodies) is a rapid and specific method for detecting and confirming the presence of neoplastic B-cell disorders. BTW, this sounds easier than it is. . Generally, a 2-10 mm section of fresh tissue is adequate.

Submit 1-3 mL if bone marrow in a special bone marrow collection tube, available by calling the NorDx Flow Cytometry Lab (207-396-7912). FC immunophenotyping studies were performed on BM or PB samples from patients with suspected NK-cell malignancies. This test is usually done after abnormal results are seen on a complete blood count or WBC differential. While morphologic assessment of blood smears, bone marrow smears, and tissue sections remains the cornerstone of lymphoma and leukemia diagnosis and classification, immunophenotyping is a very valuable and important complementary tool. The example report is intended to be a basis for further discussion within the flow cytometry cominunity on whether minimum reporting standards for leukemia and/or lymphoma flow cytometry results can and should be developed.

CAS Google Scholar This triage panel also determines if there is an increase in the number of T cells that aberrantly coexpress CD16, an immunophenotypic feature of T-cell granular lymphocytic leukemia. The results may also be used to predict how aggressive the cancer will be and/or whether it will respond to certain treatment. Flow cytometry can detect certain antigens (CD41, CD61) on the blast cells which are typical for AML-M7. This test can look at many more cells than immunohistochemistry. Cases requiring the granular lymphocytic leukemia flow panel will have an interpretation added and performed by a Mayo Clinic pathologist. The Stanford Clinical Flow Cytometry Laboratory offers a comprehensive diagnostic test menu, including leukemia/lymphoma immunophenotyping, minimal residual disease monitoring assays, CD34+ stem cell quantitation, lymphocyte subset analysis, paroxysmal nocturnal hemoglobulinuria (PNH) screen, hereditary spherocytosis, and Sézary syndrome.

Flow cytometry can also be used to test for substances called ZAP-70 and CD38 on the CLL cells. Flow cytometry is rapid and appears to be virtually diagnostic of non-Hodgkin's lymphoma when a majority of cells are B cells with an abnormal kappa/lambda ratio (> 4.0 or < 0.25). Steps in the flow cytometric analysis of acute leukemia. The most important are: Expressing antigens of another cell lineage It is abnormal to find lymphatic markers (like CD19, CD7) or markers like CD56 on myeloid cells. Inversely, it is also abnormal to find myeloid antigens like CD13 or CD33 on lymphatic cells.
