What does it mean I have a monoclonal B-cell lymphocytosis - PubMed doi: 10.1371/journal.pone.0158827. Immunophenotyping, a common application in flow cytometry, allows multiple cell surface markers to be simultaneously characterized on a per-cell basis.Immunophenotyping can be difficult by flow cytometry, however, when only a small number of cells are available. Immunophenotyping has become extremely important not only in diagnosis and subclassification of AML but also in the detection of the minimal residual disease. [Flow cytometric analysis of surface phenotypes in B-cell non-Hodgkin's lymphoma].

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. A normal cell will display a pattern of antigens that correlates with the type and maturity of the cell. Accessed April 2011. Additional FISH or molecular testing may be recommended by the Mayo pathologist to facilitate diagnosis. MDS is distinguished from other disease processes by a pattern of multiple myeloid immunophenotypic abnormalities (3-6). Chronic lymphocytic leukemia is an extremely heterogeneous disease and prognostic factors such as chromosomal abnormalities are important predictors of time to first treatment and survival.
